My cold start is 30% of that due to glow plugs and relay . Think dpf out does lot more smoke on cold start. I also get rpm flicker for 5 secs then stable to 700 rpm. Once started and warm rpm flicker isn’t there only on cold start. Maybe this is glow plug issue??
When removing the DPF the car should get a remap or be coded to get rid of the check engine. The smoke on cold starts probably is from bad glow plugs ( or relay or both :D), because it doesnt idle good when it starts and the smoke is a lot.
@@shueibdahir removing the DPF improves the engine response and gets more aggressive, but it needs to be coded because of the dpf regeneration to be stopped. And he definitely needs new glow plugs and relay, because it will always struggle like this in the mornings
@@pepigavazov I'm aware of that. Got my EGR blocked off but i'm thinking about doing this exact same thing. I'm just worried about my health and also about the smell
@@shueibdahir dont worry, you can disable the EGR by software too. I have e91 320d 163 with disabled dpf ( left the dpf body with the cat ) and egr and no worries. It has a little bit of smell but not that bad. You will be safe and the car will become faster 😀
I would absolutely recommend DPF removal for any diesel owner. The pros are huge! I did it on all my cars. I have a new 340D. DPF removed and EGR disabled. Zero smoke. Old M47/57 engine are smokey anyway. ( and btw, it looks like you removed catalytic converter as well as the dpf. General there are 2 sections, cat then dpf. Cat can be left in place. It helps with the smoke. New Common Rail engine’s dont smoke. MPG is increased massively, engine oil is as clean as petrol, my cars all passed MOT without fail. Zero engine issues. DPF are the common reason while new Diesel engines fail, turbos fail, carbon soot blockage, etc. My new M340D with downpipe is an absolute weapon. My old 535D ran for 200,000miles without a single fault. Never had chain issues or anything else. DPF removal ftw!
Hey, maybe you can help me out, hopefully lol. I had an exhaust temperature sensor problem (error code P246E00) so I replaced it, then the car went into limp mode and the coil, engine management, and dpf light came on, tried to get somebody to clean the dpf with this dpf spray cleaner stuff and it didn't work. One day (for a fill 24 hours) the car automatically came out of limp mode and then I accidentally drove through a puddle and I believe water splashed up onto some of the sensors on the underside of the car and it went back into limp mode within 3 minutes of that happening (puddle). I just got the dpf removed, egr delete and a remap but now after like 3 days the coil and engine management lights are back on. I don't know if the dpf sensors still have to be working to prevent the car from trying to do a dpf regen even after removal (I don't know if the map codes these sensors out). Any help would be massively appreciated, I'm taking the car back to the guy on Tuesday but I've been checking on loads of different forums online to no avail. Thanks in advance
Where did you go with yours to have it removed and remapped? Just got a 2015 Audi A6 2.0 TDI ultra estate as a daily( wouldnt mind a a 3 litre diesel from BMW at some point 🤗) and it has 111k miles, runs really nice but has obviously DPF, EGR and Adblue 😭😭 Do I wait till I get issues with it or remove asap? This needs to be done by someone who really know what they re doing including remap after removal. I would appreciate any details of the garage or person doing it. Are you in the UK by any chance?
If everything is working correctly and You change oil on time turbo will outlast the engine. DPF get clogged because some else is faulty like injectors, boost leak or faulty egr. DPF itself it's almost never a reason, only a result of something else working wrong. People don't maitain their cars and later they complain they work wrong. I've seen many 400kkm (250+kmiles) cars with great condition stock turbo everything, just maitained correctly and don't driving around with constantly clogged dpf for a year. If something wrong fix it asap. You can rmove it but it still don't fix your car. Find a true reason and solve it.
@@swiza79 mine was cutted, took everything from inside and weld back. Also soft for dpf removal so it won’t smoke and egr removed only from soft it costed me about 450 euros. Edit: in Romania. Some do it cheaper but I didn’t risked it
If they built DPF's the way you can manually clean them, like take it to workshop on the lift. Just get filter out in 5 minuts, clean it once a year with some chemical designed for this purpose during oil change then this suckers wouldn't be such a problem anymore but they build them so you can't do this. You need to take the whole thing out and clean it under high preassure. The result, cloggd DPF will break your car by damaging turbocharger, EGR, O2 sensors. If you have swirlf flaps or some other ridiculous elements of the exhaust system it will all break or get clogged. Sometimes before you realize you will you will burn so much oil due to a damaged turbocharger, you burn out half of what the filter was supposed to retain. Filters are designed to meet emission standards only for a certain period of time. In my opinion, manufacturers should be obliged to cover the DPF filter with a warranty for 500,000 km, including damage caused by its clogging. Then they would design them completely differently and people wouldn't cut them out, but this whole ecology thing is one big farce and a way to make even more money. Now, finally, imagine how many tortured by hat cars were scrapped and replaced by others that someone had to produce and use raw materials for production, which do not appear out of nowhere and are not transported through magical portals to factories. I am absolutely in favor of reducing emissions, but I am also absolutely against doing it the way we do it now. The consumer should have a warranty for all this that is much longer than for the car itself, because without this, manufacturers will design it the way they do just to meet emission standards and smart ass customers will get rid of it right after warranty expiration probably saving a lot of money.
A friend had the DPF removed from his Euro 5 Ford Transit (130 PS). It had been used as a delivery van, so often driving in just 1st and 2nd gear and stopping every 200 metre s. The engine was remapped at the same time. It now has nearly 150 PS and goes like a rocket. The work was done three years ago and, now with 220,000 miles on the clock, it still passes the emissions element of the annual MOT test.
@@eden4949Emissions requirements are the same for all diesel cars from 1979 to 2008. Any diesel cars newer than this have also had the same emission requirements since 2008. DPFs were only made mandatory in 2009, and removing a DPF generally doesn't bring the car under the emission requirements.

Hey. I tune alot of diesel cars and deleting DPFs is nothing new to me. The smoke you are seeing on cold starts is not a side effect of removing the DPF; that is probably a glow plug (or multiple) that are not working. Secondly I would get a quality remap done where the DPF is also deleted in the software; you would also see quite a nice HP increase. Greetings from Finland!
Hi @isak, I’m from UK, I have vw polo 1.2 Tdi. I could see my turbo doesn’t work most of the time. Showing it to a private garage they say previous owner might have removed the something inside doc (welded part could see). Does this affect my turbo. There is no warning light in my dashboard
@@hariarayakeel not sure what you mean by ”something inside doc” but i suppose youre talking about dpf? If so i suppose the previous owner cut the dpf open, removed all the ”filter” stuff in there and welded it back together. If so, it should not affect your turbo in a bad way at all👍🏻if you werent talking about emptying the dpf then my point isnt relevant
for this model, would you say getting a full straight pipe first and getting it mapped out a day later be ok? or would the dpf need to be mapped out at the same time the car is straight piped? ive been told many different stories. Kiitos :)
@@FahreFilms you need to code out dpf, the ecu after some time does dpf regen itself so after gutting the dpf you need to tell the car not to do dpf regen
@@FahreFilms to add to what others already have said, it also has to do with the air/fuel ratio, since your exhaust is a lot more high flowing now, and the map on the ECU is not made for such exhaust.
LCI 530d 173-> 223kw - 7-8 y without dpf and propery tuned, zero problems, works flawlessly. Bought when it was 178k/ km now its 320k/ km, love it. Amazing engine. Its like tuning the car whenever you add or remove things, you need tune, because its not factory settings anymore, AFR goes out of sweetspot. When you did that and no tune thats why its smokes like that, after tune it will go away. Small buff of blacksmoke is normal and on hard acceleration. Sooth will build up quickly when doing short distances.
The secret to making an M57 engine live longer - regular oil changes, swirl flap blanking, EGR disabled, and DPF "service". I have taken an e90 330d to 215k miles and it was tuned to as far as you can go with stock parts. Similar story for an e90 335d. I have also had an E65 730d but the engine blew up. Why? Swirl flap killed the engine. I also had an early M57 in an e39 530d... it didn't really have any of these systems, the engines were unstressed in their stock tune and just kept going. As for the exhaust smoke... I know that with an emptied DPF, it basically acts as a huge condensation collector. Under certain weather conditions it belches out water vapor and for longer than you'd think. But, I think some people are right - glow plugs or the control module for them are malfunctioning. Especially important as you're in Norway... nice and cold this time of year. I'd imagine the MOT testing is done with a warmed up engine in Norway?
Thank you for your answer! I've changed my glow plugs and the module but still got decent amount of cold start smoke when starting my car at ~0C temps outside. When it is warm outside I am getting almost none cold start smoke. Do you think or know by experience changing empty DPF to a downpipe will solve the cold start smoke? Or at least reduce it to a non existent amount?
ive done my fair share of dpf. You getting white smoke engine is cold on start because your glow plugs arent preheating the cylinders enough. Thats why your DPF was clogged and robbing your power. Getting rid of healthy dpf wont gain you any more. Definitely look into replacing glow plugs
@Fahre Films I'll try to share my experience in regards to emissions systems on diesels. 1st car: 2008 Alfa romeo 159 2.4 liter diesel engine with 210hp. With DPF+CAT+EGR+swirl flaps in the intake the cars fuel consumption city couldn't go below 12.5liters/100km. Car got mechanical removal of DPF+CAT+swirl flaps , egr delete and a software coding to "turn off" those systems. Result : same car, same driver, fuel consumption dropped to 9.5 liters/100km. Smoke problems on newer diesel cars are mainly related to fuel injectors and lugging your engine while driving at lower speeds. 2nd car is 2002 Seat Toledo with the famous 1.9 tdi 110hp. That is my daily car, and without removing anything it used 6.5liters/100km in city driving. Tires were Dunlop Sportbluresponse 2 195/65 r15. I have removed the rear muffler and went with 225/45 r17 wheel setup. Fuel consumption dropped by 0.8liters/100km. It still has egr(turned to minimum with VCDS). DPF contains palladium that is very expensive ore and has a high refund when scrapped. Does it filters particles-yes, but have you ever driven behind car that has one and you feel that "rotten eggs" smell in your cabin? Voila, you have just inhaled the same "nasty" emissions from that car just with reduced size that not even surgical mask can hold, they attach to your bronchioles unlike old diesels that definitely pollute but have larger size particles. You want an efficient diesel? Remove dpf, turn it of, leave the CAT, if EGR is controlled by vaccuum, leave it on, get a catchcan and clean your intake manifold. And most important thing-enjoy wrenching 😁.
Hello You have to cancel dpf from the software because the engine will regenerate dpf. In this case, the injectors will give more fuel that will not be used and will go into the engine oil. Good luck.
JOOOOOOOOOOOOOOOOOOO!!!! Replace those glow plugs my friend! They are done! I did them too last month because it started like that too, with smoke and I have a good DPF. Now that my glowplugs and the distributer thingy is new it starts up really healthy again! And it does not start like a tractor!
Removing DPF, swirl flaps & EGR blanking is always good for these engines as they breathe better. As soon as you remove them the first thing is get it tuned and get coded. And btw always keep your DPF just incase you fail your MOT. Even tho they will 100% sure know that you have gutted the DPF they still have obligation to pass your vehicle.
did you get low bost or poor performance at low rpms after removing the swirl flaps?, im thinking of doing it but i find people saying better not to doit
Well in my 535d m57 i removed all the "eco" stuff from it, and there is no smoke at all. The intake manifold was very dirty, so I cleaned it up and removed flaps from it. The next thing I've done is decoded egr and dpf from the ECU, because even if you have empty dpf, it will still try to burn it off. I've also give a big IC to be sure twin turbo system was fine. The last step i need to do is to make new engine map, so there were no smoke and the combustion is as efficient as it could be. So if you want your exhaust are clean in m57: 1) remove egr and dpf, and decode them from ECU 2) check the IC if its working well and check the turbos for oil leak 3) clean the intake manifold and check/clean Crankcase ventilation 4) if you have no problem with a money - check/repair injectorst 5) do proper engine mapping Enjoy pure efficiency and no smoke!
Got my dpf removed on f10 520d 135kw and car doesn't smoke on startup or acceleration. It passed MOT without any problems and fuel consumption is better. It has 297000k kilometers on clock and I would recommend it to everyone. Just make sure your injectors are good!
in latvia slooowly start checking MOT diesel particles if they have suspect about removed DPF or client is too agresive in MOT time . i have DPF and have no plans to remove it .
If you have get a remap you don't need a "chip" tune. The former is the way to go, chip tunes are plug and play devices you can remove BUT they're visible and are generalized, so they're not tailored for your build
After DPF removal do remap to your engine ECU it would not smoke so bad on cold start. My cousin has E61 530d also with DPF removed. on cold start ir spreads just a little blue smoke. but you can turn engine off and start again on cold engine it wont smoke.. and car runs much better without that DPF.
I’ve got a tuned 330d. Dpf is still active and has caused me no problems while regenerating perfectly. I put this down to only using high quality super fuel and maintenance. Shiny exhaust tips and never seen a single puff of smoke!!
Anything prior to Euro 4 may not be a problem. From Euro 5 onwards, it could likely cause engine damage & send your car into Limp mode if the DPF is removed . There are sensors linked into the cars ECU etc . Probably not a good idea . But in countries with pretty lax emissions standards, you'd probably easily get away with it. Anywhere on Euro 6 or 7, wouldn't be worth the risk
I took the DPF out of my mk3 Mondeo 10 years ago never had any sort of problem, there a puff of smoke on start up ands that's it, the benefits of removing the DPF massively out number the negatives.
Removing yields less back pressure, less strain on turbo, this also results in less soot getting pushed by the piston rings and you will not need to run low ash oil. and you will get better sound. If you delete dpf heating and regen from ecu you will gain some economy. Engine will have to do marginally less work and produce less heat. Using less diesel. (Marginal). You will let tiny diesel particulets and nox out into atmosphere, theese are very dangerous, especially if you also remove cat. On newer common rail diesel, unburnt diesel mist is so microscopical that the hairs in your nose and lungs will not be able to stop it, and you will get the toxins directly into the bloodstream when breathing in the smoke.
I saw a video testing what hp gains you could get from removing a catalytic converter which is pretty close to the restriction from a dpf. He gained like 40-50hp at redline because the exhaust now moves faster and the turbo spools faster and higher rpms. The wastegate wasn't enough to control the boost after cat removal.
@@samp6162 actually it was a miata, but still. why should any car manufacturer design the wastegate any better than they need to? it is designed to work with cat or dpf
@@simenskaar5843 Miata and MX5 is the same, different names for different areas in the world (I'm UK). The wastegate is part of the crappy eBay turbo, not the car manufacturer (Mazda). The car did not have a turbo from factory.
Problem with people today is that they take the car for small trips and the engine don't have the chance to get to its working temp and the dpf/catalytic won't work when they are cold. And it results in blocked dpf and cats, not good for the engines etc.
Its a euro 3. No problems with mot. I had a bmw 116d from 2009 and removed the dpf and had a custom tune. It runs 194 hp without smoke. Only the smell of the exhaust was a pain in the ass. If i was you i did a custom remap.
🫣If you want my advice for working on a 535d.. Check temps.. Get a good quality swirl flap delete kit with new intake gaskets. All new glow plugs and check module…. CLEAN the EGR. (don’t delete it.. It’s illegal + it only operates/restricts on start up) Replace vacuum pipers and pressure converters.. Change engine oil and filter and if you have the money, especially on an old car if it hasn’t been done before, change the transmission fluid along with the diff. Now while doing that take off the dpf and soak it in hand hot water before popping in a dishwasher table. (This will break down the greasy stuff) Let it soak then rinse with a hose pipe. Next buy some brick cleaner or pool acid HCI and mix it with water 1/4 or 1/3 parts water and pour it in, soak and keep rinsing it through. I.e. Filthy EGR’s and DPF’s cause the restrictions..clean ones don’t really.. New panel air filter and a proper dyno tuned remap and you’re at 340+ hp with a MOT passing car. 🤷
Damnnnn that cold start, the car surely has 2-3 glowplugs shot, it sounds like it struggles to keep idle when cold starts. Maybe that's why it smokes that bad, it'll surely smoke with dpf off but it's way too much :D
Yeah lol i cant believe this guy didnt realise this, i was shocked when mine did the same in winter after i bought it, new glowplug controller and its alot better along with new thermostat so that it reaches operating temp alot quicker which the glowplugs also help with
My experience with dpf removal....My first dpf car (I had petrol cars or pre dpf diesel cars before this) was a mk5 2007 golf gt sport mapped to 220bhp...the car was incredible and I loved it but the stupid dpf broke the car by blocking the air flow and destroying the engine after 26 days of owning the car!!! (no warning lights nothing just bang, smoke, dead car and the aa garage mechanic said "the dpf strikes another nice car down"), I then got a 2012 mk7 golf gt 150bhp which I ran for around 6 months before dpf messages so I ran it on the motoway (im uk) for a good hour or so and they went off, a week or so later they are back so I have to do it again only this time they don't go off so I pay £500 for a dpf cleaning and carry on.....3 months later dpf light comes on so at this point im not happy so I take it back they clean it again (for free this time) and I leave......2 weeks later and BOOM the car is crying about the dpf again only this time the people won't clean it and say it must be an issue go to vw to let them have a look and refuse to refund me (fair enough I guess) so vw tell me it will be 2k for them to sort this issue it needs a new dpf so I said fk that and sold it on as a car that needs to have a new dpf......I then get a 1.6 tsi golf 160bhp (if you cant tell I love a golf haha) and you all know where this is going (anyone in the car game will know anyway) that 1.6 engines creator has a special place in hell for what he did with that engine so after that car broke I talked to a mate who is a car guy and he said get a diesel gt again but get the dpf removed I said it wont pass mot tho he said yea it will he knows a guy who does a good job with them where the mot guy will never know.....I now have a dpfless mapped 200bhp mk7 2013 gt golf with 0 issues and have been driving it for 3 years all with no issues and the best bit is it sails through mot's everytime and drives perfect (also no black smoke unless I hit like 4k revs which yes I do all the time lol but idle there is no smoke so I don't think it's the dpf delete doing that with your car as my dpf remover told me cars with black smoke are normally running bad glow plugs or have bad maps and whats worse is the dpf hides the fact you have issues by removing the smoke).
Basically don’t do a DPF delete without programming the ecu to map out the dpf function other wise you will have some kind of negative effect example more smoke or constantly trying to regenerate which will either fill the sump with diesel as it injects more fuel in regen mode and escapes past the piston rings and worst case destroy the engine because of this
i had removed DPF on my scirocco for 4 years without any problems seriously, and 3 days ago i sold the car and the new owner keep it without dpf, ofc i give him the original dpf but nobody likes dpf even its illegal :D + also on 4:20 in the video, its common rail fuel injections and when you took out the DPF you probably didn't disable the DPF regeneration in ECU, thats why you have visible smoke
Removing DPF in NO??!! You’re courageous 😂😂 In many places MOT is a joke on what concerns emissions, but the amount of smoke the car does may get you in trouble sooner than later!
Your engine needs maintenance, that cold start is not normal even for a DPF removal... Check your injectors and your glow plugs, they are without a doubt in need of maintenance.
So much black smoke during a cold start, the reason lies in a bad engine or just in the injection system, nozzles, etc. On the 535d, I removed the dpf and closed the egr, while doing the obligatory remap of the software. A little smoke will appear when the weather is cold and the engine is cold, then when you suddenly add gas, then the fuel cools the pistons suddenly and does not burn fuel well, but it is nowhere near as much as in the video.
I have a e280 cdi stage 1 ecu remap, very hard stage 1 increased from 190hp to 252-254hp, but it was done 3 years ago, one month ago i removed the dpf and it doesnt smoke at all, like not at all, neither white or black smoke, and never turns on the check engine light, maybe cars can produce smoke in cold starts because of bad injectors or bad glow plugs, mine with dpf in 2023 would struggle to start or wouldnt start at first just the second time because of my glow plug, and embarrased us in the city with all that white smoke
I have a 2007 Volvo c30 1.6 diesel. My dpf stopped regenerating even if I added Eolys, so I chose to delete it. It was a service special for tunning. The guys from there cut the dpf, took what's inside it and weld it back as an empty case. They deleted both dpf and egr from soft. It only made a little smoke on a winter cold start but nothing in comparison to your bmw. It was only about 2 seconds and barely visible. Though it doesn't feel faster, maybe it just moves better at low torque. Also my car stopped shaking
If you want your turbo to live rip out the DPF and straight pipe it, egr delete, and performance map. Like you mention in this video the entire engine feels as if it can actually breath properly, hardly surprising when you look at the DPF and see what a horrible restrictive piece of junk it is in terms of airflow. This plus change the oil every 10k and these straight six engines will run forever.
as a Diesel Mechanic that works on semis/box trucks and pickup trucks i can say, with every fiber in my body, that EVERY single Diesel engine is better WITHOUT dpf and EGR than WITH. emissions are the only reason for both of these features and i assure you, they do not help with longevity. it is not even up for debate. though, with that, requires a complete remap and if you have a VGT you will need someone that REALLY knows their shit. there should barely be any soot out of the exhaust at full load/boost. if there is, its too much fuel. if its coming out blue, thats straight unburnt fuel. raw diesel. common rail fuel injection with their unreal high pressure allows for A REAL efficient burn in the cylinder. hell.. my old 1998 12.7 S60 detroit engine with a 550hp remap at 1850tq doesnt blow a puff of black out of the exhaust. 1.3 million miles. 6.5-7.2.mpg 63mph cruising speed.
I’ve had an E34 524td, an E39 525tds and 530d, and an E61 525d (2.5). None of them had a dpf and none of them smoked on cold start. You want to start checking resistance on your glow plugs (iirc around 1 Ohm and all within 0,2 Ohm of each other). Very common failure point on these engines are the plugs and the relay, but you want to check the wiring too. If all that checks out, I’d suspect a leaking injector.
@@adamsmv2512 if you’re going for a 530d, go with a manual. BMW used an automatic transmission barely strong enough for a completely standard engine, if you want a remap or more… it’s going to fail. It’s a GM box iirc, not a 5hp from ZF
DPF delete (DPF not catalytic converter) is the best option for high mileage engines or worn engines that burn oil or have worn/bad injectors. New DPF would be garbage in less than 10k miles. If your engine does not burn oil and injectors are ok then a new DPF would be better
Removing DPF and EGR is a bad idea and a crime in many states. By removing DPF and EGR you gain like 7 extra horsepower, which is nothing. Of course, the tunning capability of the car increases, but it is such a bad idea to mess with the exhaust system of the car. Just remove the intake and clean it every 5 - 6 years and you are good to go. My car has soot free exhaust system, and it has 176.000 km, an E90 N47 from 2010. And it doesn't smell bad behind the car, unlike cars without DPF.
The cold start will improve dramatically when remapped to suit. I had a straight piped 330cd that smoked badly until mapped and then there was next to no smoke afterwards.
Best reaction is 2400rpm, but some problems can cause because of the fail it is going to give you on the dashboard because of the sensors in the car, but it is not a big deal. But you engine is more healthier than before bro👍 (check engine remap)
I have always thought dpf and egr Are The engine killers when engines get older. If the engine has some small "problem" wich may not even be much, other of those two Will make it more worse. Old Mercedes engines with no those dpf and egr. Million km on board? No broplems other than those small witch dont bother at all.
Just cut the DPF and get a second stage tune at least. World of difference and no negatives imo. Your smoking issues are excessive, run some additives to clean up injectors and your crank case. As far as emissions go.... Think about your mileage compared to the rest of the guzzlers on the road!
in Arizona (USA) removing DPF is sort of like pot, illegal on the Federal level but legal on the state level 😁 this year our EPA (environmental protection agency) made it illegal for any shop to remove cats of dpfs, that means we have to do it ourselves or go to a un-registered shop that will do it for us. BTW a 200 cell high-flow cat on your mid pipe will get rid of the smoke and odor (for the most part)
You need to remove the DPF form the software and EGR too! Now easily you can get on stage 2. Have a nice remap and even your smoke should reduce. If you blank your EGR too smoke will be minimized… if you need a software for it hit me up
My Saab 9-3 TTID 08 has had the pre-cat delete, dpf delete, egr blanked, flapless intake manifold installed but really wasn’t happy till it was mapped to disable the dpf. It kept trying to regen a hollow box basically because the pressure was wrong in the dpf and engine computer assumed it was blocked and sometime about 800km I experienced limp mode a couple times
Have you had a visit by local police by now? In Germany, removing a DPF would land you in serious trouble - and most MOT engineers are well capable of spotting the welding of DPF casing that has been opened and welded shut again...
@vikingsmb hello mate iv very recently had my dpf removed, I can smell fumes but doesn't smoke badly iv had it mapped out done right but it now has nothing between the engine and talepipe. do you think I will pass mot its it's a 2 series 2014 euro 5. in good condition and 77000on the clock. iv just ordered that emissions reducer you recommend. but because I call smell fumes I'm very concerned about the mot in march
If you want a faster car, get a petrol, engineers spent years researching and designing modern engines and working to keep the emissions down. Then you clme along and think you know best by removing the dpf, the correct thing to do is get the dpf professionally cleaned.
Cold start smoke is from dpf didn't deleted from ecu and 2nd your car has some issues with injector quantities. Check injectors and good to go 👍 p.s I do lot of these every week 😉
Unfortunately without that procedure a diesel car will end up costing you more in maintenance (new injectors, turbo and dpf cleaning procedures) compared to gasoline gars. Which on its own makes no longer sense of owning a diesel car. There could be two reasons: bad fuel or not pushing the car enough - yes new diesels must be driven a bit harder. Where I live the bad quality diesel fuel is enemy number one.
How about that cold start haha! Smash the notification bell and like the video :)
My cold start is 30% of that due to glow plugs and relay . Think dpf out does lot more smoke on cold start. I also get rpm flicker for 5 secs then stable to 700 rpm. Once started and warm rpm flicker isn’t there only on cold start. Maybe this is glow plug issue??
Remap and you will see different car
In bulgaria we haven't got controls and everything is legal
dude check the glow plugs and module or fuel injectors because you can hear the engine running badly cold dpf removal is not related to smoke
@@zilve5546 dpf removal leads to more smoke but not that bad.
What’s rpm flickering due to EGR or glow plugs
Does never happen when it’s warmer though
When removing the DPF the car should get a remap or be coded to get rid of the check engine. The smoke on cold starts probably is from bad glow plugs ( or relay or both :D), because it doesnt idle good when it starts and the smoke is a lot.
Exactly.
I was just about to say the same. I think the reason it got clogged in the first place is because of those glow plugs. They can ruin a DPF pretty fast
@@shueibdahir removing the DPF improves the engine response and gets more aggressive, but it needs to be coded because of the dpf regeneration to be stopped. And he definitely needs new glow plugs and relay, because it will always struggle like this in the mornings

@@shueibdahir dont worry, you can disable the EGR by software too. I have e91 320d 163 with disabled dpf ( left the dpf body with the cat ) and egr and no worries. It has a little bit of smell but not that bad. You will be safe and the car will become faster 😀
I would absolutely recommend DPF removal for any diesel owner. The pros are huge! I did it on all my cars. I have a new 340D. DPF removed and EGR disabled. Zero smoke. Old M47/57 engine are smokey anyway. ( and btw, it looks like you removed catalytic converter as well as the dpf. General there are 2 sections, cat then dpf. Cat can be left in place. It helps with the smoke. New Common Rail engine’s dont smoke. MPG is increased massively, engine oil is as clean as petrol, my cars all passed MOT without fail. Zero engine issues. DPF are the common reason while new Diesel engines fail, turbos fail, carbon soot blockage, etc. My new M340D with downpipe is an absolute weapon. My old 535D ran for 200,000miles without a single fault. Never had chain issues or anything else. DPF removal ftw!
Hey, maybe you can help me out, hopefully lol.
I had an exhaust temperature sensor problem (error code P246E00) so I replaced it, then the car went into limp mode and the coil, engine management, and dpf light came on, tried to get somebody to clean the dpf with this dpf spray cleaner stuff and it didn't work.
One day (for a fill 24 hours) the car automatically came out of limp mode and then I accidentally drove through a puddle and I believe water splashed up onto some of the sensors on the underside of the car and it went back into limp mode within 3 minutes of that happening (puddle).
I just got the dpf removed, egr delete and a remap but now after like 3 days the coil and engine management lights are back on. I don't know if the dpf sensors still have to be working to prevent the car from trying to do a dpf regen even after removal (I don't know if the map codes these sensors out).
Any help would be massively appreciated, I'm taking the car back to the guy on Tuesday but I've been checking on loads of different forums online to no avail.
Thanks in advance
Where did you go with yours to have it removed and remapped? Just got a 2015 Audi A6 2.0 TDI ultra estate as a daily( wouldnt mind a a 3 litre diesel from BMW at some point 🤗) and it has 111k miles, runs really nice but has obviously DPF, EGR and Adblue 😭😭 Do I wait till I get issues with it or remove asap? This needs to be done by someone who really know what they re doing including remap after removal. I would appreciate any details of the garage or person doing it. Are you in the UK by any chance?

@@liamsxa I'm thinking to cut mine,u have any ideas how much it costs?
If everything is working correctly and You change oil on time turbo will outlast the engine. DPF get clogged because some else is faulty like injectors, boost leak or faulty egr. DPF itself it's almost never a reason, only a result of something else working wrong. People don't maitain their cars and later they complain they work wrong. I've seen many 400kkm (250+kmiles) cars with great condition stock turbo everything, just maitained correctly and don't driving around with constantly clogged dpf for a year. If something wrong fix it asap. You can rmove it but it still don't fix your car. Find a true reason and solve it.

@@eriktenhag2022 It's more a culture thing.
@@Jin-Ropolitics does stem from culture
If they built DPF's the way you can manually clean them, like take it to workshop on the lift. Just get filter out in 5 minuts, clean it once a year with some chemical designed for this purpose during oil change then this suckers wouldn't be such a problem anymore but they build them so you can't do this. You need to take the whole thing out and clean it under high preassure. The result, cloggd DPF will break your car by damaging turbocharger, EGR, O2 sensors. If you have swirlf flaps or some other ridiculous elements of the exhaust system it will all break or get clogged. Sometimes before you realize you will you will burn so much oil due to a damaged turbocharger, you burn out half of what the filter was supposed to retain. Filters are designed to meet emission standards only for a certain period of time. In my opinion, manufacturers should be obliged to cover the DPF filter with a warranty for 500,000 km, including damage caused by its clogging. Then they would design them completely differently and people wouldn't cut them out, but this whole ecology thing is one big farce and a way to make even more money. Now, finally, imagine how many tortured by hat cars were scrapped and replaced by others that someone had to produce and use raw materials for production, which do not appear out of nowhere and are not transported through magical portals to factories. I am absolutely in favor of reducing emissions, but I am also absolutely against doing it the way we do it now. The consumer should have a warranty for all this that is much longer than for the car itself, because without this, manufacturers will design it the way they do just to meet emission standards and smart ass customers will get rid of it right after warranty expiration probably saving a lot of money.
I agree the technology wasn’t fully ready for it to get clogged so easily I’ve always had diesels they have ruined them witn this filter
A friend had the DPF removed from his Euro 5 Ford Transit (130 PS). It had been used as a delivery van, so often driving in just 1st and 2nd gear and stopping every 200 metre s. The engine was remapped at the same time. It now has nearly 150 PS and goes like a rocket. The work was done three years ago and, now with 220,000 miles on the clock, it still passes the emissions element of the annual MOT test.
How comes they pass MOT without a DPF?
@@eden4949Emissions requirements are the same for all diesel cars from 1979 to 2008. Any diesel cars newer than this have also had the same emission requirements since 2008.
DPFs were only made mandatory in 2009, and removing a DPF generally doesn't bring the car under the emission requirements.
Hey. I tune alot of diesel cars and deleting DPFs is nothing new to me. The smoke you are seeing on cold starts is not a side effect of removing the DPF; that is probably a glow plug (or multiple) that are not working. Secondly I would get a quality remap done where the DPF is also deleted in the software; you would also see quite a nice HP increase.
Greetings from Finland!
Hi @isak, I’m from UK, I have vw polo 1.2 Tdi. I could see my turbo doesn’t work most of the time. Showing it to a private garage they say previous owner might have removed the something inside doc (welded part could see). Does this affect my turbo. There is no warning light in my dashboard
@@hariarayakeel not sure what you mean by ”something inside doc” but i suppose youre talking about dpf? If so i suppose the previous owner cut the dpf open, removed all the ”filter” stuff in there and welded it back together. If so, it should not affect your turbo in a bad way at all👍🏻if you werent talking about emptying the dpf then my point isnt relevant
Hii there uu mention that u tune alot of diesels i wanted a adwice from uu for my bmw 320d f30 how much hp can i get with dpf remove and a remap plz?
Great, I was mentioning dpf. Your comment really helps.
for this model, would you say getting a full straight pipe first and getting it mapped out a day later be ok? or would the dpf need to be mapped out at the same time the car is straight piped? ive been told many different stories. Kiitos :)
You need a remap after DPF removal, it should not smoke like that even on cold starts
Or it has bad glow plugs that's why its missfiring and smoking on cold start ;)))
I have heard about the remap after delete, but why ? 🤷🏼♂️ Feel like I don’t know enough about this
@@FahreFilms you need to code out dpf, the ecu after some time does dpf regen itself so after gutting the dpf you need to tell the car not to do dpf regen
And the car still believe it has backpressure from the dpf
@@FahreFilms to add to what others already have said, it also has to do with the air/fuel ratio, since your exhaust is a lot more high flowing now, and the map on the ECU is not made for such exhaust.
LCI 530d 173-> 223kw - 7-8 y without dpf and propery tuned, zero problems, works flawlessly. Bought when it was 178k/ km now its 320k/ km, love it. Amazing engine.
Its like tuning the car whenever you add or remove things, you need tune, because its not factory settings anymore, AFR goes out of sweetspot. When you did that and no tune thats why its smokes like that, after tune it will go away. Small buff of blacksmoke is normal and on hard acceleration. Sooth will build up quickly when doing short distances.
The secret to making an M57 engine live longer - regular oil changes, swirl flap blanking, EGR disabled, and DPF "service". I have taken an e90 330d to 215k miles and it was tuned to as far as you can go with stock parts. Similar story for an e90 335d. I have also had an E65 730d but the engine blew up. Why? Swirl flap killed the engine. I also had an early M57 in an e39 530d... it didn't really have any of these systems, the engines were unstressed in their stock tune and just kept going.
As for the exhaust smoke... I know that with an emptied DPF, it basically acts as a huge condensation collector. Under certain weather conditions it belches out water vapor and for longer than you'd think. But, I think some people are right - glow plugs or the control module for them are malfunctioning. Especially important as you're in Norway... nice and cold this time of year. I'd imagine the MOT testing is done with a warmed up engine in Norway?
Thank you for your answer! I've changed my glow plugs and the module but still got decent amount of cold start smoke when starting my car at ~0C temps outside. When it is warm outside I am getting almost none cold start smoke. Do you think or know by experience changing empty DPF to a downpipe will solve the cold start smoke? Or at least reduce it to a non existent amount?
@@LeoNofcourseno it won't. The flow of the downpipe has nothing to down with smoke.
4:13 - there is something broken man. There is no way car smoke like this on cold start. Injectors or glow plugs to check. ;)
always liked how e60 looks I think it aged good
It looks way more new than 2004
ive done my fair share of dpf. You getting white smoke engine is cold on start because your glow plugs arent preheating the cylinders enough. Thats why your DPF was clogged and robbing your power. Getting rid of healthy dpf wont gain you any more. Definitely look into replacing glow plugs
True!
Usually its glow plug controller that goes bad
@Fahre Films
I'll try to share my experience in regards to emissions systems on diesels. 1st car: 2008 Alfa romeo 159 2.4 liter diesel engine with 210hp. With DPF+CAT+EGR+swirl flaps in the intake the cars fuel consumption city couldn't go below 12.5liters/100km. Car got mechanical removal of DPF+CAT+swirl flaps , egr delete and a software coding to "turn off" those systems. Result : same car, same driver, fuel consumption dropped to 9.5 liters/100km. Smoke problems on newer diesel cars are mainly related to fuel injectors and lugging your engine while driving at lower speeds.
2nd car is 2002 Seat Toledo with the famous 1.9 tdi 110hp. That is my daily car, and without removing anything it used 6.5liters/100km in city driving. Tires were Dunlop Sportbluresponse 2 195/65 r15. I have removed the rear muffler and went with 225/45 r17 wheel setup. Fuel consumption dropped by 0.8liters/100km. It still has egr(turned to minimum with VCDS). DPF contains palladium that is very expensive ore and has a high refund when scrapped. Does it filters particles-yes, but have you ever driven behind car that has one and you feel that "rotten eggs" smell in your cabin? Voila, you have just inhaled the same "nasty" emissions from that car just with reduced size that not even surgical mask can hold, they attach to your bronchioles unlike old diesels that definitely pollute but have larger size particles. You want an efficient diesel? Remove dpf, turn it of, leave the CAT, if EGR is controlled by vaccuum, leave it on, get a catchcan and clean your intake manifold. And most important thing-enjoy wrenching 😁.
Hello You have to cancel dpf from the software because the engine will regenerate dpf. In this case, the injectors will give more fuel that will not be used and will go into the engine oil. Good luck.
Best thing for diesel engines is dpf off and AGR off ,swirl flaps off and the engine will thank you every time you drive it.
JOOOOOOOOOOOOOOOOOOO!!!! Replace those glow plugs my friend! They are done! I did them too last month because it started like that too, with smoke and I have a good DPF. Now that my glowplugs and the distributer thingy is new it starts up really healthy again! And it does not start like a tractor!
Removing DPF, swirl flaps & EGR blanking is always good for these engines as they breathe better. As soon as you remove them the first thing is get it tuned and get coded. And btw always keep your DPF just incase you fail your MOT. Even tho they will 100% sure know that you have gutted the DPF they still have obligation to pass your vehicle.
did you get low bost or poor performance at low rpms after removing the swirl flaps?, im thinking of doing it but i find people saying better not to doit
@low boost or poor performance are caused by poor tune. First thing you do after DPF removal is tune.
@@grgrider8642 ok thanks ill try to find a good tuner for my car
Tell me about it, mine didn't pass mot with gutted dpf so now I'm temporary fitting one so I can pass, hopefully no engine lights go on
Well in my 535d m57 i removed all the "eco" stuff from it, and there is no smoke at all. The intake manifold was very dirty, so I cleaned it up and removed flaps from it. The next thing I've done is decoded egr and dpf from the ECU, because even if you have empty dpf, it will still try to burn it off. I've also give a big IC to be sure twin turbo system was fine. The last step i need to do is to make new engine map, so there were no smoke and the combustion is as efficient as it could be.
So if you want your exhaust are clean in m57:
1) remove egr and dpf, and decode them from ECU
2) check the IC if its working well and check the turbos for oil leak
3) clean the intake manifold and check/clean Crankcase ventilation
4) if you have no problem with a money - check/repair injectorst
5) do proper engine mapping
Enjoy pure efficiency and no smoke!
Thank you for your comment 🙏 very helpful 👍🏼 😊 ❤
The smoke on cold start is becuse of the glowplugs or the module! You can hear that it struggles to stay on in idle
Great vid man, helped .I've just had mine gutted tonight and dropped it off for remap. See what it's like tomorrow. 👍
Got my dpf removed on f10 520d 135kw and car doesn't smoke on startup or acceleration. It passed MOT without any problems and fuel consumption is better. It has 297000k kilometers on clock and I would recommend it to everyone. Just make sure your injectors are good!
Chain ok?
@@victor_h9925 yeah, replaced at 200k
in latvia slooowly start checking MOT diesel particles if they have suspect about removed DPF or client is too agresive in MOT time . i have DPF and have no plans to remove it .
If you have get a remap you don't need a "chip" tune. The former is the way to go, chip tunes are plug and play devices you can remove BUT they're visible and are generalized, so they're not tailored for your build
After DPF removal do remap to your engine ECU it would not smoke so bad on cold start. My cousin has E61 530d also with DPF removed. on cold start ir spreads just a little blue smoke. but you can turn engine off and start again on cold engine it wont smoke.. and car runs much better without that DPF.
I’ve got a tuned 330d. Dpf is still active and has caused me no problems while regenerating perfectly. I put this down to only using high quality super fuel and maintenance. Shiny exhaust tips and never seen a single puff of smoke!!
Anything prior to Euro 4 may not be a problem. From Euro 5 onwards, it could likely cause engine damage & send your car into Limp mode if the DPF is removed . There are sensors linked into the cars ECU etc . Probably not a good idea . But in countries with pretty lax emissions standards, you'd probably easily get away with it. Anywhere on Euro 6 or 7, wouldn't be worth the risk
Yeah, my E60 is euro 4 :)
I took the DPF out of my mk3 Mondeo 10 years ago never had any sort of problem, there a puff of smoke on start up ands that's it, the benefits of removing the DPF massively out number the negatives.
Removing yields less back pressure, less strain on turbo, this also results in less soot getting pushed by the piston rings and you will not need to run low ash oil. and you will get better sound.
If you delete dpf heating and regen from ecu you will gain some economy. Engine will have to do marginally less work and produce less heat. Using less diesel. (Marginal).
You will let tiny diesel particulets and nox out into atmosphere, theese are very dangerous, especially if you also remove cat. On newer common rail diesel, unburnt diesel mist is so microscopical that the hairs in your nose and lungs will not be able to stop it, and you will get the toxins directly into the bloodstream when breathing in the smoke.
Imagine running hvo100 how clean it would be 😀
I saw a video testing what hp gains you could get from removing a catalytic converter which is pretty close to the restriction from a dpf. He gained like 40-50hp at redline because the exhaust now moves faster and the turbo spools faster and higher rpms. The wastegate wasn't enough to control the boost after cat removal.
The turbo mx5 video. Yeah he had an eBay turbo and the crappy wastegate didn't work properly so he had boost creep.
@@samp6162 actually it was a miata, but still. why should any car manufacturer design the wastegate any better than they need to? it is designed to work with cat or dpf
@@simenskaar5843 Miata and MX5 is the same, different names for different areas in the world (I'm UK). The wastegate is part of the crappy eBay turbo, not the car manufacturer (Mazda). The car did not have a turbo from factory.
I did it and its great! Fuel consumption lowered by 0,7L. 535D (chip remapped ofc)
Problem with people today is that they take the car for small trips and the engine don't have the chance to get to its working temp and the dpf/catalytic won't work when they are cold. And it results in blocked dpf and cats, not good for the engines etc.
You should do what I think you should do with your car because I’m a person on the iternet
Its a euro 3. No problems with mot. I had a bmw 116d from 2009 and removed the dpf and had a custom tune. It runs 194 hp without smoke. Only the smell of the exhaust was a pain in the ass. If i was you i did a custom remap.
Dpf and egr remove is best thing that can diesel engine get in their entire exploitation time. Engine will be clean and healthy.
🫣If you want my advice for working on a 535d.. Check temps.. Get a good quality swirl flap delete kit with new intake gaskets. All new glow plugs and check module…. CLEAN the EGR. (don’t delete it.. It’s illegal + it only operates/restricts on start up)
Replace vacuum pipers and pressure converters.. Change engine oil and filter and if you have the money, especially on an old car if it hasn’t been done before, change the transmission fluid along with the diff.
Now while doing that take off the dpf and soak it in hand hot water before popping in a dishwasher table. (This will break down the greasy stuff)
Let it soak then rinse with a hose pipe.
Next buy some brick cleaner or pool acid HCI and mix it with water 1/4 or 1/3 parts water and pour it in, soak and keep rinsing it through.
I.e. Filthy EGR’s and DPF’s cause the restrictions..clean ones don’t really..
New panel air filter and a proper dyno tuned remap and you’re at 340+ hp with a MOT passing car. 🤷
I drive a Golf IV TDI. No need for a delete if it never had a DPF in the first place ❤
So good looking car🤩
You should do it and do remap because:
More power
More Torque
More fast
More sound
Better fuel economy
Damnnnn that cold start, the car surely has 2-3 glowplugs shot, it sounds like it struggles to keep idle when cold starts. Maybe that's why it smokes that bad, it'll surely smoke with dpf off but it's way too much :D
Yeah lol i cant believe this guy didnt realise this, i was shocked when mine did the same in winter after i bought it, new glowplug controller and its alot better along with new thermostat so that it reaches operating temp alot quicker which the glowplugs also help with
Little tip, If you put premiums diesel or use a product to raise the octane you will easily pass the emissions test
Oh then hvo100 should be perfect
@@drivingbro Would leave your MOT center scratching their heads lol
fortes emission treatment is the best, and change the air and fuel filters, also use shell v power as well
I don't have the dpf and egr and it never smokes. You have to check the glow plugs or/and injectors
My experience with dpf removal....My first dpf car (I had petrol cars or pre dpf diesel cars before this) was a mk5 2007 golf gt sport mapped to 220bhp...the car was incredible and I loved it but the stupid dpf broke the car by blocking the air flow and destroying the engine after 26 days of owning the car!!! (no warning lights nothing just bang, smoke, dead car and the aa garage mechanic said "the dpf strikes another nice car down"), I then got a 2012 mk7 golf gt 150bhp which I ran for around 6 months before dpf messages so I ran it on the motoway (im uk) for a good hour or so and they went off, a week or so later they are back so I have to do it again only this time they don't go off so I pay £500 for a dpf cleaning and carry on.....3 months later dpf light comes on so at this point im not happy so I take it back they clean it again (for free this time) and I leave......2 weeks later and BOOM the car is crying about the dpf again only this time the people won't clean it and say it must be an issue go to vw to let them have a look and refuse to refund me (fair enough I guess) so vw tell me it will be 2k for them to sort this issue it needs a new dpf so I said fk that and sold it on as a car that needs to have a new dpf......I then get a 1.6 tsi golf 160bhp (if you cant tell I love a golf haha) and you all know where this is going (anyone in the car game will know anyway) that 1.6 engines creator has a special place in hell for what he did with that engine so after that car broke I talked to a mate who is a car guy and he said get a diesel gt again but get the dpf removed I said it wont pass mot tho he said yea it will he knows a guy who does a good job with them where the mot guy will never know.....I now have a dpfless mapped 200bhp mk7 2013 gt golf with 0 issues and have been driving it for 3 years all with no issues and the best bit is it sails through mot's everytime and drives perfect (also no black smoke unless I hit like 4k revs which yes I do all the time lol but idle there is no smoke so I don't think it's the dpf delete doing that with your car as my dpf remover told me cars with black smoke are normally running bad glow plugs or have bad maps and whats worse is the dpf hides the fact you have issues by removing the smoke).
Definitely worth doing it with egr and swirl flaps delete plus tune
Basically don’t do a DPF delete without programming the ecu to map out the dpf function other wise you will have some kind of negative effect example more smoke or constantly trying to regenerate which will either fill the sump with diesel as it injects more fuel in regen mode and escapes past the piston rings and worst case destroy the engine because of this
i have a F21 116d with egr off and dpf removed. got remaped and runs 183 hp. 205.000 km on it, no issues.
i had removed DPF on my scirocco for 4 years without any problems seriously, and 3 days ago i sold the car and the new owner keep it without dpf, ofc i give him the original dpf but nobody likes dpf even its illegal :D
+ also on 4:20 in the video, its common rail fuel injections and when you took out the DPF you probably didn't disable the DPF regeneration in ECU, thats why you have visible smoke
did you ever have any issues with the police with it deleted?
@@tylerclanfield5429 i never got pulled over so ya, i know im lucky :D
Removing DPF in NO??!!
You’re courageous 😂😂
In many places MOT is a joke on what concerns emissions, but the amount of smoke the car does may get you in trouble sooner than later!
not a chiptune but optimization. chiptune was somthing we did a long time ago. soldering in a chip in the ecu. :)
I bet this guy is a blast at the party's
you still need to delete the dpf in the ecu, worth to get a stage 1 remap as well
Your engine needs maintenance, that cold start is not normal even for a DPF removal... Check your injectors and your glow plugs, they are without a doubt in need of maintenance.
Man... Check your glowplug module and glowplugs... That cold start so lumpy is because of that (most of smoke too) E61 530d owner here from Copenhagen
So much black smoke during a cold start, the reason lies in a bad engine or just in the injection system, nozzles, etc.
On the 535d, I removed the dpf and closed the egr, while doing the obligatory remap of the software.
A little smoke will appear when the weather is cold and the engine is cold, then when you suddenly add gas, then the fuel cools the pistons suddenly and does not burn fuel well, but it is nowhere near as much as in the video.
I had e60 30xd at 270kkm dpf removed stage 1 soft and ran as good as before sold it at 450kkm in the clock
White smoke is a sign of burning oil , id get a compression test done , also get a catch can especially if you get a remap.
Guys if you have a Van, remove your DPF as it will get rid of all the problems, I done it 4 years ago and it’s perfect !
if u remove dpf filter u need 1 stage remap to sort smoking problem
That smoke is not normal on cold start.. I'd say you need new glow plugs
I have a e280 cdi stage 1 ecu remap, very hard stage 1 increased from 190hp to 252-254hp, but it was done 3 years ago, one month ago i removed the dpf and it doesnt smoke at all, like not at all, neither white or black smoke, and never turns on the check engine light, maybe cars can produce smoke in cold starts because of bad injectors or bad glow plugs, mine with dpf in 2023 would struggle to start or wouldnt start at first just the second time because of my glow plug, and embarrased us in the city with all that white smoke
I have a 2007 Volvo c30 1.6 diesel. My dpf stopped regenerating even if I added Eolys, so I chose to delete it. It was a service special for tunning. The guys from there cut the dpf, took what's inside it and weld it back as an empty case. They deleted both dpf and egr from soft. It only made a little smoke on a winter cold start but nothing in comparison to your bmw. It was only about 2 seconds and barely visible. Though it doesn't feel faster, maybe it just moves better at low torque. Also my car stopped shaking
If you want your turbo to live rip out the DPF and straight pipe it, egr delete, and performance map. Like you mention in this video the entire engine feels as if it can actually breath properly, hardly surprising when you look at the DPF and see what a horrible restrictive piece of junk it is in terms of airflow. This plus change the oil every 10k and these straight six engines will run forever.
as a Diesel Mechanic that works on semis/box trucks and pickup trucks i can say, with every fiber in my body, that EVERY single Diesel engine is better WITHOUT dpf and EGR than WITH. emissions are the only reason for both of these features and i assure you, they do not help with longevity. it is not even up for debate.
though, with that, requires a complete remap and if you have a VGT you will need someone that REALLY knows their shit. there should barely be any soot out of the exhaust at full load/boost. if there is, its too much fuel. if its coming out blue, thats straight unburnt fuel. raw diesel. common rail fuel injection with their unreal high pressure allows for A REAL efficient burn in the cylinder. hell.. my old 1998 12.7 S60 detroit engine with a 550hp remap at 1850tq doesnt blow a puff of black out of the exhaust. 1.3 million miles. 6.5-7.2.mpg 63mph cruising speed.
I’ve had an E34 524td, an E39 525tds and 530d, and an E61 525d (2.5). None of them had a dpf and none of them smoked on cold start. You want to start checking resistance on your glow plugs (iirc around 1 Ohm and all within 0,2 Ohm of each other). Very common failure point on these engines are the plugs and the relay, but you want to check the wiring too. If all that checks out, I’d suspect a leaking injector.
Wanting to buy either e39 or e60 3 liter, which one you liked more?
@@adamsmv2512 hmmmm, E60 better power and transmission, E39 is a better car. Handling is very similar, E60 has a bit more room inside.
@@stefan2meteryeah I’m leaning towards the e39, was considering the petrol variant as well but not too sure
@@adamsmv2512 if you’re going for a 530d, go with a manual. BMW used an automatic transmission barely strong enough for a completely standard engine, if you want a remap or more… it’s going to fail. It’s a GM box iirc, not a 5hp from ZF
@@stefan2meter will do, I now drive 520i e39 manual but it has insane lack of power, besides that I love the car
DPF delete (DPF not catalytic converter) is the best option for high mileage engines or worn engines that burn oil or have worn/bad injectors. New DPF would be garbage in less than 10k miles. If your engine does not burn oil and injectors are ok then a new DPF would be better
with the remap it wont smoke that much on cold start but if you are looking for HP its going to smoke...
Removing DPF and EGR is a bad idea and a crime in many states. By removing DPF and EGR you gain like 7 extra horsepower, which is nothing. Of course, the tunning capability of the car increases, but it is such a bad idea to mess with the exhaust system of the car. Just remove the intake and clean it every 5 - 6 years and you are good to go. My car has soot free exhaust system, and it has 176.000 km, an E90 N47 from 2010. And it doesn't smell bad behind the car, unlike cars without DPF.
The cold start will improve dramatically when remapped to suit. I had a straight piped 330cd that smoked badly until mapped and then there was next to no smoke afterwards.
Best reaction is 2400rpm, but some problems can cause because of the fail it is going to give you on the dashboard because of the sensors in the car, but it is not a big deal. But you engine is more healthier than before bro👍 (check engine remap)
I have always thought dpf and egr Are The engine killers when engines get older. If the engine has some small "problem" wich may not even be much, other of those two Will make it more worse. Old Mercedes engines with no those dpf and egr. Million km on board? No broplems other than those small witch dont bother at all.
My DPF in my 320d E91 was clogged and got so hot, that my car removed the cat and DPF on the Autobahn by itself. My car nearly caught fire 😅
The issues maybe, after a few months , smoke will come out exhaust, i believe u have to maintain motorway drives after its removed
To All diesel owners... Is the best to delete dpf. All works fine. More power more torque more responsive
Put your headseat to your head my friend. You don’t wanna have a whiplash in an accident.
Very few disadvantages to removing DPF, same goes for EGR's.
Just more cancer for everyone 👍
Just cut the DPF and get a second stage tune at least. World of difference and no negatives imo. Your smoking issues are excessive, run some additives to clean up injectors and your crank case. As far as emissions go.... Think about your mileage compared to the rest of the guzzlers on the road!
in Arizona (USA) removing DPF is sort of like pot, illegal on the Federal level but legal on the state level 😁 this year our EPA (environmental protection agency) made it illegal for any shop to remove cats of dpfs, that means we have to do it ourselves or go to a un-registered shop that will do it for us. BTW a 200 cell high-flow cat on your mid pipe will get rid of the smoke and odor (for the most part)
You need to remove the DPF form the software and EGR too! Now easily you can get on stage 2. Have a nice remap and even your smoke should reduce. If you blank your EGR too smoke will be minimized… if you need a software for it hit me up
I’ve removed the dpf and I need the the file to code it out I have a engine light from it
My Saab 9-3 TTID 08 has had the pre-cat delete, dpf delete, egr blanked, flapless intake manifold installed but really wasn’t happy till it was mapped to disable the dpf. It kept trying to regen a hollow box basically because the pressure was wrong in the dpf and engine computer assumed it was blocked and sometime about 800km I experienced limp mode a couple times
what destroys engines prematurely is the egr. not removing the catalist.
Have you had a visit by local police by now?
In Germany, removing a DPF would land you in serious trouble - and most MOT engineers are well capable of spotting the welding of DPF casing that has been opened and welded shut again...
In Holland you can remove it if the car is from 2011 or older.
@@Zuudloarn dont know why they dont do that here in the uk
@vikingsmb hello mate iv very recently had my dpf removed, I can smell fumes but doesn't smoke badly iv had it mapped out done right but it now has nothing between the engine and talepipe. do you think I will pass mot its it's a 2 series 2014 euro 5. in good condition and 77000on the clock. iv just ordered that emissions reducer you recommend. but because I call smell fumes I'm very concerned about the mot in march
Yes defo get your remap done asap👍
Great video thank you man
If you want a faster car, get a petrol, engineers spent years researching and designing modern engines and working to keep the emissions down.
Then you clme along and think you know best by removing the dpf, the correct thing to do is get the dpf professionally cleaned.
I have f31 330d 2012 without dpf egr and swirl flap and does not smoke at all
Change your glow plugs and that should get rid of the smoke
That cold start, i think there's other problems there like a duff injector.

You should put the sound loudness to the negative side. Why people like loud crappy cars? I could never understood that.
Cold start smoke is from dpf didn't deleted from ecu and 2nd your car has some issues with injector quantities. Check injectors and good to go 👍 p.s I do lot of these every week 😉
Unfortunately without that procedure a diesel car will end up costing you more in maintenance (new injectors, turbo and dpf cleaning procedures) compared to gasoline gars. Which on its own makes no longer sense of owning a diesel car. There could be two reasons: bad fuel or not pushing the car enough - yes new diesels must be driven a bit harder.
Where I live the bad quality diesel fuel is enemy number one.
Not necessarily, ive seen some cars for sale that gone almost 400k km with original dpf
Can this process be reveresed? And if so, how much would it cost?
I don't think my passat b5 has filters because it is euro3, 1.9 TDI 116 HP
Only Cat
yours will only have cat, same as mine, as mines euro 4 57 plate 2.0 tdi 138 BKP engine, so glad I dont have a DPF on mine
removed it on my bmw e90 2012 went through eu controll no problem
Can you do the remap and see how it runs? want to remove mine!

There are no negatives. Just get the car mapped correctly. The bad cold start and smoke is glow plugs
