I HAVE NOW FIXED THE ISSUE: ruclips.net/video/Ff60sMnS5z8/видео.html
Change the back pressure sensor always the issue when it won’t regen
I totally agree with you. So the average 10 year old car will end up being scraped because something fitted to it fails and costs too much to fix, now this complete car is going to have to be recycled which is counter productive and will generate pollution getting rid of it and then another car will be built to replace it causing even more damage to the environment. It is far better to keep a good car going until it is truly beyond its usefulness.
Exactly!
Its only bad for the environment when companies cannot make money from it or when government cannot make tax from it
I checked the back pressure before the dpf using ista, maybe try that to see if its blocked. It revs up the engine by itself apart from the last check, great to watch.
I played a drinking game, every time George says regeneration I took a shot.
I currently have liver failure.
😂😂😂
Its a temperature sensor problem mate which is situated on the exhaust close to the motor.
Now to clean your DPF just use DASTY Degreaser, let it sit overnight and it is brand new.I have use this on my dpf of my car and it worked amazingly.Dont need to spend 150£ to let your dpf flush and cleaned.
My 5 series 2.0d is ten years old, done 120,000 miles and I have never had a problem with dpf. I was told that constant around town driving is the main cause of issues.
Correct!!!
I have a bmw e65 730d with 169,000 miles and my dpf its totally fine. Bmw dpfs are usually bomb proof, never had any bother, mine regens when your driving in town even. In the family we have 320d a 335d, 730d, x3 2.0d, 520d, x1 2.0d and a x5 3.0d. I have friends with diesel bmws and no problems.
I've had my 2006 E91 330d for 6 years and never had any major problems or error messages. Only issue I've had is the old quacking EGR valve issue. Replaced with another used part from ebay for £20 and another 2 years in without issue. When taking out the old EGR it wasn't overly mucky either.
Don't know if this is testament to the 6 pot diesel, good servicing or just luck. Do mainly town driving, but do have a 1 or 2 30min drives at 60mph every month. Either way looks like I'm one of the lucky ones 😅
Just did a long 1000km autobahn trip in my 2015 316d touring, after 2 years of mostly short-ish trips because of the pandemic. Car feels a lot better than it did before, consumption went way down.
As others have mentioned you should not keep the revs high... Measure the exhaust gas temp before DPF and you'll see it start steadily climbing once above 50mph, when hot enough should start burning the soot mass.... You should also check to see if coolant temp drops below 60c when driving over 50 over a long period of time. If so it is your thermostats.. i would measure these parameters with ista whilst driving by recording the screen or something... see if the soot mass & ash goes down at all (passive regen)..
Hi George superb video... feel your pain with the dpf system playing up only car I've had with any dpf problem was my 07 c max many years ago... Was never the same and just got rid of it. Want a F10 520d m sport in the near future... I love them! Everyone dreams of super cars! All I want is a F10 520d msport that's my dream car 👍
Similar problem with my 2016 Cx5, tried regen no luck. Actually the warning light came on when I was over 300km from home. I drove back at 120kph in outside temperatures of 35°c. Sweet FA!
Eventually took it to Mazda Dealership, took them a few hours for a computer "burn off" 6 months on now, no problems fingers crossed!!
If it does return I ll either remove it or do a chemical clean. Thankfully they're not mandatory here!! Cheers for the video George.
I had the exact same problem so I replaced the DPF filter and still had the same problem. In the end after around £2000 I replaced the exhaust sensor on the manifold and reset , worked fine but cost me a lot of money !!
Absolutely agree with the dpf. I bought a Mk8 transit it had huge issues with the dpf till I deleted it along with the egr.
Did you pass an mot? I just had my egr and dpf mapped and the guy suggested removing the dpf but won’t this fail on emissions?
I had DPF problems on my Mitsubishi Outlander 2007, as the the car did not have a dedicated dpf icon but used the engine management light, this light commonly came on when the Dpf needed to be regenerated. However as the car had done over 100.000 miles it was a pain with engine fans keep come on and the car becoming quite hesitant at times when driven.
I was advised due to the amount of miles on the clock the dpf woukd require replacing ....£££££
Hi George, 4:32, it says “as soon as the fault no longer occurs, the DDE will perform a normal regeneration” the car may not be able to regenerate because of the fault code. the exhaust pressure might be too high to regen?
I had same problem. The other condition required is engine coolant temp above 75°. I checked the thermostat in a saucepan and thermometer and it was opening at 68° changed for a new one and bingo, finally regenerated.
Hi George. I can see your problem on the ISTA while you are driving very clearly. Your back pressure reading is way too high. The ecu won’t start a regeneration unless the back pressure according the ISTA SHOULD BE WITHIN THESE RANGES: less than 35 mbar at idle, less than 75 mbar at 2000 RPM and less than 200 mbar at cut off engine RPM which is about 4000 RPM. The ISTA will do that test for you. It will rev the engine automatically during the test and the end will tell you the 3 readings and the maximum permissible values as I mentioned above. It is a safety feature because a regen with a heavily blocked dpf might set a fire. Of course you know your both egr and main engines thermostat should be working fine, the diesel in the tank as you mentioned shouldn’t be low, of course your glow plugs and the control unit should be working, good working egr and no fault code stored in the ecu. Another reason for such high back pressure reading is a a faulty back pressure sensor which is about £30. I had the same problem. I had an on car dpf cleaning twice. It doesn’t work. What I did I took the dpf to a place near Blackpool, I live in northwest, they pump flush cleaned the dpf in about an hour for £150 just then BINGO, the pressure readings came down hugely just like what you get from a brand new dpf. Of course there is a very important thing which most of people don’t know. In the ecu software if the mileage of the car is 150 000 miles then even if the dpf is not blocked and other parameters are normal, still the dpf won’t regenerate until you go through a dpf replacement procedure in the ISTA, even if you physically installed a brand new OME DPF. By the way my car is 520d, M47 engine, 57 registration plate. Hope that will help you. Again please don’t spend any money on ON CAR DPF cleaning, specially you can take out the dpf out of the car your self. Good luck
Hello, are you suggesting to reset the Dpf counter?
@@kirwanjohn101 if the DPF cleaned professionally and the back pressure is reading really low, something like less than 10 mbar at idle, then sure you need to reset the DPF which I think it will give you another 250000 km.
This happened to my sister's 1 series, told it the dpf had been changed and it fixed it
It will regenerate, you just need to keep clearing the errors. While on the motorway it slowly regens passively and it increases exhaust temperature regardless of the backpressure. Mine used to get to about 400-450C for about 10 minutes before chucking an error and failing. You need to clear the error while driving and carry on until eventually it will passively unblock itself enough to blast the temps to 600-650C. Once it hits that it usually clears the soot all the way through.
I have a Peugeot 3008 Diesel Hybrid (2014) and it performs a Re-Gen automatically and tells me that it is doing it.
I have never had an issue with the DPF on any car which I have had, and I don't do huge miles. Removing it makes your car illegal and uninsurable, so if it is working fine then leave it in place. Most failures seem to stem from other issues anyway which cause it not to regen properly. Failed thermostats being a common one.
EGR is a major headache too!!!
@@paulmcdonald8055 They can be, I haven't had major issues on any of my diesel cars but the one on my N57 is mapped out. (but still in place if anyone tries to look at it)
If you understand how the car works they can be managed quite well. My new petrol car has a ppf
Totally agree, nanocarbon molecules are filtered for a reason as they cause cancer.
Thermostat.
Glow plugs.
Glow plug module.
Driving around on an empty tank all the time.
Short journeys.
Crapy diesel.
Crapy fuel filter.
Crapy engine oil.
The list is absolutely endless.
Great video, very helpful. Waiting for the resolution !
I had the DPF light on mine and on inspection it was just the o2 sensor. Changed that and has been fine since.
It is only there to make governments feel better
I don't know about that because they said downtown London air smells like diesel.
I agree with the DPF removal from the 10th year onwards. I bought an used E81, 14 years old. Soon the DPF light went on, but as a new car owner, I talked to a friend and by his advice tried to fix it by regen, long drive at 2000rpm. My fault. The result was the turbine broke it's axis after a highway drive. Everything's ok now, but the high pressure from a blocked DPF is not something to be neglected, no matter the extent of blockage.
I had the same issues.. until I started using premium diesel and keeping the tank over half full. You will get a shock at MOT time when they see you removed the DPF... Its an automatic fail and there is a large fine for the driver... Replace the DPF pressure sensor I guarantee thats why you are unable to get the regen done...
Premium fuel - - agree. I have had issues in the past using supermarket fuel.
Hi George great vid. I have a audi a3 2015 keep having the glow light flashing and goes into limp mode especially when the engines cold revs at 1000 rpm all the time switch engine off and back on again light stops flashing and it goes out of limp mode no dpf light though and no fault codes on diagnostics I'm just wondering if I have the same problem?
From what I know, the regen starts when driving at over 60 kph, but the engine should not be revved over 2500rpm. It should work somewhere between 2000 and 2500 rpm. I have an E90 320d as well, and had no issues with my dpf until now. Hope that helps 👍
Learnt a lot from this one Bud thank you
Best thing I ever did .. cut along welds clean out ceramic muck ..re weld then remapped
Job done ✔️
Did pass mot
Just a note of support. To tackle such issues in real time is impressive. I agree with you on DPF. I have 13 year old 520D with 72k which has had a very easy life. It is only used on journeys over over 100 miles no short journeys. The car is immaculate but will I get another 7 yrs out of it. Its electric and high tech issues which will condemn it to the scrap heap which in a holistic view is not good. I will only buy Toyota from now on
Your a poes
I had the same problem, in the end it was down to the Sensors and that was with a new DPF
Hi George I suspect it wont re-gen because the dpf is blocked at the back with ash. Dpf's do have a limited lifespan & will only re-gen so many times before they need replacing because when it re-gens whilst it burns the soot out this process produces ash which can't be removed/burnt out of the dpf, & the ash builds up at the back of the dpf causing the differential pressures from the front to the back of the dpf become too large (implausible) giving you the trouble codes I think you've got. I had a problem with a ford galaxy that wouldn't re-gen. It had similar trouble codes & would go through the motions but would not re-gen. It turned out that the differential pressures form the front of the dpf to the rear of the dpf were too great which think is what your diagnostics are suggesting. There are companies that clean dpf's & they always clean them back to front to force the ash out of the front of the dpf. In my case the dpf was too far gone & had to be replaced because the diesel catalytic converter had broken up & also blocked the dpf. once I replaced the catalytic converter & dpf the car did a re-gen straight away without me having to request one because it was happy with the differential pressures. I also found out that some dpf's re-gen much more frequently than most people think as watching it on live data after I had done the repair it regenerated several times on a 60 minute journey & that was with all new parts. I hope this help you.
BMW cars have backpressure sensor not differential pressure sensor. It uses only one hose plugged from the DPF
@Antonio Carsa what I meant was there are two pressure sensors one at the front & one at the back of the dpf & the ecu measures the difference between the two sensors, hence differential pressure
@@simonkeable391 BMW does not have a pressure sensor after DPF. There are two sensors. One mounted before the turbocharger in the exhaust manifold and one before the DPF/OxyCat. The backpressure measurement is based on the difference between the pressure read with engine off and with engine running.
My Alfa 159 tells me when it needs a dpf regeneration on the dashboard - mine is the later 2.0 jtdm. Alfa placed the dpf nearer to the exhaust manifold in the 2.0 models, which makes the regen far more efficient.
Had similar on my e60 530d, turned out to be an injector issue which failed attempts to regen
Had exactly the same codes with my e91 320d. Removed the DPF twice and cleaned thru after failing to start a regen. In the end I gutted it, refitted and blanked off the EGR and had a simple plug a pray map to remove them. Absolutely no faults since, car went from around 50mpg to 60+mpg (872 miles to the tank the best). Also no smoke other than the small amount you would expect from any diesel under load
And your car is polluting like hell. Nitrous oxides are invisible, but toxic, carcinogenic. If you do not have money for spare parts use a petrol car.
Gotta love a dirty diesel 😀
You can only regen with the engine management system... my brother in law sorted mine after I had done what you did... plugged in the engine code thingy, looked for it, did what was needed then it was perfect again...
This issue depends on the make of diesel engine. I have a nine year old KIA 1.6 diesel that has spent its life doing very short runs interleaved with motorway runs every few months, the DPF copes with this. It helps when the filter is clamped to the exhaust manifold (quick to get to working temperature).
You had any EGR issues with your Kia? I got a 1.6 Proceed and it throws a pending code P0404 roughly once a week. Heard lots of people replacing EGR but the problem persists.
@@jamiewright3901 I feel like the Germans do a better job of the diesels, though Japanese and Korean petrol cars are rock solid.
@@elijahcarr4137 Definitely, I got the Kia as they were going for not much more than half the price of Audi/VW at the time, to add I fixed the EGR fault by simply taking the solenoid off the top and cleaning around the pin and stuck half a can of brake cleaner through the top of the valve. Sorted.
It is illegal to remove a DPF filter on a vehicle that is 2009 or later that has it fitted as standard.
This is a 2008
There is a lot of things illegal in this country like motor garages and politics
Not illegal to remove one, but an mot fail.
@@spudhead1161 actually it IS illegal because it changes the emissions levels of the vehicle and so would leave you liable to tax evasion.
@@petelattimer6808 NOT ILLEGAL TO REMOVE FROM A CAR, YOU CAN REMOVE ANYTHING FROM YOUR CAR. BUT AN MOT FAIL. Tax evasion ? haha ffs.
Never had any issues with regens. I was told if you use the wrong oil it can cause issues with regen process
It is illegal to drive your diesel vehicle without the dpf if one should be fitted in the UK . I put a dpf cleaner through the dpf to clean it and it passes MOT every time. You have to drive it afterwards but be warned to do it on a private road because it smokes for a while. It looks as if the mist came up from the ocean behind you but after that the dpf is clean and emissions are within limits.
Do you have your own private road?
It is a catch 22 as you can't remove a DPF as it is an instant MOT failure. If you have someone in the know, great but it still seriously impacts resale if you remove the system. It is worth noting that in most modern diesels the DPF won't regenerate if other error codes are present so make sure you have deleted all codes via a scanning tool before trying a regen. I have had a fair few issues with the DPF on my Jag XF. There are DPF cleaning services now at most garages, even Halfords do it, so it doesn't have to be too expensive. Also worth noting for the more environmentally and health minded people out there that if you delete the DPF there will be much more of the black stuff with pm10s being emitted.
Just get a Euro3 diesel mate and you can forget about crappy DPF's! Euro4 onwards with DPF's and swirl flaps etc are a frikkin pain.
Removal of the DPF is illegal as it comes under emissions control systems. Without a DPF and without EGR valves a large volume of NoX gases are emitted which are the gases that contribute to lung diseases and respiratory illnesses. DPFs are a serviceable item and convert soot that is collected by the particulate filter by into ash by high temperature burning. The ash is retained in the filter and eventually reaches a "full" level which no regeneration will reduce. Then it is time to clean or replace the filter. I have done this on my TDI Passat at 150k as it was used for a daily 35 mile commute so passive regeneration occurred due to constant high DPF temperature. Have never had a DPF light or fault code and replaced when regenerations became very frequent. Shorter journeys would have invoked active regenerations which the ECU controls by increasing fuelling and the ash content accumulates more quickly. There is no issue with having DPFs if you understand what they are, how they work and that they will need to be cleaned or replaced every 100 to 150k on average. My Passat is at 230k now - still no DPF issues.
@@MiracleMitch Not illegal, just an mot fail.
@@spudhead1161 You will find that in the UK removal of any emissions controlling parts on a motor vehicle is not illegal, but by law, DRIVING a vehicle whereby factory fitted emissions parts have been removed IS illegal. So basically you can remove a DPF and thereafter, if it does not fail the next MOT test, and you can get the car to the test station without driving it, you can look at your DPF removed car for ever more but just can't DRIVE it LEGALLY! 😂😂 Same thing then really isn't it? Shame it is so badly policed as I'm sure it would prevent small children from getting lung disorders from nearby diesel traffic fumes, particularly NoX gases.
How do I know this apart from having researched this to death? Brother's partner is a lawyer, sister is a police officer, brother is a police officer, father is a mechanic. Want the piece of legislation - I can get this for you too!? Or you can just Google it for yourself 🤔
@@MiracleMitch Certainly not the same thing is it? I don't care you have police in the family, is that supposed to make you right? haha. Do police check if cars have DPFs? certainly not.
Completely agree with your summary at the end mate.
Hey George, enjoying the content.
My previous car (Octavia VRS CR TDI), would regen fairly regulary, probably every other month. I would know it was doing it because the idle speed would sit at 1000rpm rather than 750rpm as normal. If I finished my journey and it was idling high, I'd know it was doing it's regen and carry on driving for a little while. Do BMWs not do this? Seems a bit rubbish to not know when it's doing a regen!
Not that I’ve noticed mate
I’ve got a 2005 e90 330d manual and the few ways I can tell it’s in regen mode is that it wants to hold a high rev range feels like it wants to push a bit more than what your holding on the accelerator.
also a sharp little push on accelerator and you get a sound like it’s puffing out steam and a slight bit of movement but this I’m sure you’d only be able to do in a manual.
I’ve have my 330d for 6yrs and it regularly does a 200 mile regen so I click the mileage reset bottom so I know it’s soon going to happen. Got the car on 85k and it’s now on 116k.
@@terrybooya6132 6 years and you’ve done about 30k?
@@piovo5222 yeah about 30k. And I’ve had my fair share of the DPF getting blocked. Never experienced limp mode tho
@@terrybooya6132 I’m surprised everything’s not blocked to be honest.
Removing that would be a guaranteed MOT fail.
Not if you know a guy that knows a guy 😏
My BMW E91 320d LCI has 186k miles on it and it has the original DPF. The exhaust backpressure sensor should be changed every 60-70k miles (it`s a piezzo part and exhaust temperature along with soot will make it give wrong info to ecu). Also you should check your entire engine (worn injectors/turbo/piston rings will cause building up more soot in your dpf). Removing your dpf should be the last option and I would not recomend removing it unless your engine is pretty much worn out
I have had my 7 year old C4 115 bhp diesel for six years now and it has passed every MOT (4) with no advisories and I only do local urban driving. I have only replaced discs and pads on it so I hope I have it for another six.
Had the dpf removed from my vw van and it feels like it’s been racing tuned, I’m all for the dpf purge
Normally you have to clear codes before it will allow a regen.
Had same issue once on my C30 but cleared codes and it allowed the regen then.
I also ended up removing it a month later and washed it out snd fitted a hybrid turbo not had one issue since.
Dpfs on this generation of BMW’s are sensitive to the following components functioning properly:
- glow plugs & module
- main & egr thermostats
- throttle control actuator connected egr
Not sure if you’ve already trouble-shooted those areas?
Yep all working fine. It’s sorted now so will have an update video coming soon👍🏻
@@GeorgeAusters Nice one George, enjoying all your videos bud! We love our BMWs
I have a glow plug module fault on my 330 M57 and it still regenerates. It wouldn’t though until I changed stuck open thermostat
Just to add George I also had the back pressure sensor signal warning as well .. my hunch is that it's not the sensor itself that's faulty (I bought another one and swapped it.. no difference!) but rather it's reading a high pressure value due to the blocked DPF and is therefore raising the fault code. It also seems the system is self defeating.. like it can't run a regen because it has a fault code.. but as you can't GET it to regen what the hell are you supposed to do? Ultimately as mentioned in another post I just replaced mine and it's been fine since... Verified that regenerations were happening since r replacement successfully. Though I haven't checked it in a while so maybe I should.. 😆
I didn't take the route of DPF deletion due to the prospect of trouble at the MOT.
I have another video coming with a resolution👌🏼
they can't tell if done properly
@@doctord8589 That's what I would have thought.
Don't know about diesels, is a DPF just for emissions? is there and performance difference with or without it?
I had a 520d e60 m47 engine with the same dpf problem and same fault codes, I cleared the codes then requested a regeneration and then changed from ista to inpa started the car and drove it while someone kept pressing the erase fault codes button on the laptop as inpa erased the codes continuously and quicker than ista, this worked for me
I believe the n47 dpf service light comes on at 150k saying to change it ,I reset mine using diagnostics ,and cleaned it with using sol x cleaner.i have not had any problems since.The Nct test (national car test in Ireland) similar to mot in uk,are now starting to check cars soon to see if the dpf has been removed by using diagnostics and this will be a fail if no live data is seen for dpf.
Volvo v50 245000 miles no dpf issues though the front struts needs replacing worn out now and 1 top bearing cranking noise when I turn full lock towards the right .
Hi George, great video . I've seen someone a while ago showing how the dpf is not regenerating if the rev is over 2000 RPM even if is up to temperature, unfortunately I can'tfind the video again . Try to do a trip at a normal RPM 1800 - 2000 . Hope it helps !
Nothing to do with rev range mate. I have sorted it though, a video will be out in the near future👍🏻
@@GeorgeAusters hurry up lol im having the same problem right now on a 520d m sport lol
keep up the good work mate well done
There is only one problem or perhaps two. One, after a certain date, if your vehicle was fitted with a dpf and it is missing at time of mot test this vehicle will fail the test and that also includes if there is evidence of tampering of the dpf ie the internals being removed.
Two doing this contravenes the construction and use regulations of the vehicle and VOSA will if you have been found to have tampered with your in such a way, will hit you hard with nasty legal stuff.
To a certain extent I have sympathy with the people who own vehicles with dpf problems, because they are a pain in the arse.
You are 100% correct to do a registration you need to keep the revs within normal driving range around 2000 rpm or just under. If you over rev it like in this video it wont regenerate.
Took my 3.5 year old Vauxhall Astra 2.0 Cd SRi into lookers (main dealer) in Oct 2015 with low oil pressure warning after the engine would crank as too much oil in system. Turned out the extra diesel that is pumped in to burn the exhaust gases is designed to be dumped into oil sump! - that was the last I saw of the car, Lookers tried regen and couldn’t after trying several things they told me the next thing to “try” was new injectors @ £2000 but could not guarantee that would work - told them I wanted Vauxhall involved but vauxhall point blank refused to do so - would never buy another Vauxhall on that basis again
I had an issue on my e250. The temperature sensor was faulty so the regeneration was not happening. Even when I was on the motorway for 2 hours.
My brakes are squealing. I know I'll remove them. Sorted!
In Germany is illegal, if they caught you with dpf delete then you have big problems.
Yep German Tuv inspection is tough!
It’s also illegal to remove in uk will fail an mot if removed or visibly tampered with.
@@GeorgeAusters I bought a new dpf from Bosal and I was thinking to put in on only when I go to TÜV but if police stops me in traffic without dpf then It's bad, it is like my car is euro 0 and I prefer to make every 1-2 year a dpf and egr cleaning rather than risking to be caught, it's cheaper..
You need someone sitting next to you deleting both of the dpf codes, that was the only way I managed to get mine to regen, but yes the DPF are the cause of a lot of trouble
Yes I have a video coming on this👌🏼
i had a problem with mine, car wouldnt pull you out of bed, took it out profiessionaly cleaned and still running but you're right about them
before you want to remove egr now dpf what next to remove in your car
In some countries, a dpf delete will render your vehicle unroadworthy, therefore also not insurable. The legal issues could easily escalate. Replacing a dpf is cheaper.
Another great video bro!
Cheers mate
Hi pal I’ve got a 2010 Audi A3 2.0tdi. I get this dpf issue your getting but a motorway spin at 2.5k rpms & 20-30 mins tend to clear it
Hello bro great video, can removing dpf cause problems with the engine
Also it could be an underlying issue other than dpf filter it could be a leak from your turbo intercooler hose pipe (split pipe) or it could be a dirty maf sensor.
I made an update video how I fixed the issue
Check the hose that connects to the back pressure sensor, I believe its called the manifold pressure sensor hose. Did you or I should ask would you consider using additives to the fuel like Wynns DPF cleaner?
All additives essentially do is help the combustion temps thus the exhaust temps reach a little higher
I see from your responses that you have rectified the problem. Looking forward to your update. Im assuming you removed and cleaned the DPF? To be honest I'm thinking of doing the same but I guess we will soon find out what you done 😉
Is a red hot exhaust tip a sign car is in the middle of a regen?
Have a 520d and noticed one day while standing behind it after a drive that the exhaust was making a tinkling sound and was red hot to touch.
Not necessarily
When the car reaches approx 250k km approx 150k miles the dpf fault code will come up even if the dpf is still good because from factory the max usage of the dpf is 250k km. What you need to do is reset the dpf by telling the system that you have changed the dpf without really changing it. There are a couple of videos on RUclips about this issue and on how to program this.
Hi. I work in the filtration industry and wondered why people don’t change out the DPF for a new one if the filter is clearly clogged and issues persist? Is it particularly costly? Thanks.
Very costly - Over $7,000 on my Mazda 6
ive got a 2.0ltr citroen C5 the ECU remembers old faults no matter what. so it may be that your old faults are still showing up after a regen? try deleting the old faults and running the car again and doing another diagnostic to see if they return.
Hey George, nice video, recently been doing the same with dpf issues. Can i ask you about other think tho, my N47 when i turn it off it does not turn imidiately like a friend's e82, his engine shuts off normaly but mine takes a bit more revolutions and shudders a bit. What can cause that? I have already replaced the anti shudder valve.
Any fault codes?
@@GeorgeAusters no fault codes
Scotty Kilmer say's, give yourself a fancy scantool :-)
The problem started when car manufacturers stated in the late 90's the new commonrail diesel injection engine's would never need the glow plugs replaced.
That's why dpf/egr exists today but just to replace glow plugs every 30k was all that was required.
I have a 2008 diesel. New enough for common rail old enough to not have a DPF. It goes like stink and if you rev it you almost always get black smoke. Its always serviced and runs perfectly.
My US spec 2014 VW Sportwagen was modded to remove the emissions cheat software after being sold back. I have not noticed the regen ever taking place. Will it show in the OBD2 codes with a basic code reader?
I doubt it, you likely need proper VAG software
Have you try Forte products?
I'd managed to fix blocked DPF in Volvo V50 with Forte additative 😊. Engine oli had to change after this procedure...
Would you have a link to where you bought your ista+ from mate ?
I thought it was illegal to remove the DPF.
You cant remove the dpf it an mot fail now if it is missing,,you need to getca garage rhat knows what they are doing removing dpf and reinstalling the dpf casing and remap the car,,,but you just cant do away with it physically altogether.,,also removing dpf often make car smoke a little and that may be a mot issue depending where you take it for mot.
The problems with Dpfs regenerations can be caused by multiple situations, one of the most important is the turbo system not working properly. I had problems with my diesel car, during several years, just because there was a very small hole in the solenoid vacuum hose of the turbo, that no mechanic noticed and that no error code diagnostic! I discovered the problem by myself.
If you remove the inside filters of the dpf and just put the part back on, how will they be able to check on MOT that the filter is not there?
They won’t
The trouble is if past owner have not looked after dpf then no amount of regen will work its either a clean hoping the surface are notvdamage or a new one
Under the new mot the have to visually check for different and next year there will be a computer check if it missing then your car fails mot.
Great vid info. Can you tell me the legalities of removing be the dpf and egr...for mot etc...thanks.
Technically illegal and should fail MOT. Don't actually remove the DPF, have it gutted (insides removed) then put back on and mapped out. The MOT check is simply to check the DPF is installed.
I have 280,000 km on the original dpf. Its good to take it on long trips. I also use cetane booster in the fuel.
The problem with DPF's on BMW's is that they fill up with ash created by the soot being burned during re-gens. Eventually no amount of re-gens will work because the DPF is actually blocked with ash, not soot. I had a 530d and went through this process countless times. Nothing I did made any difference. Tried countless re-gens, passive and active. It drove me insane in the end.
Watch my other video, it’s sorted now
Great video thnx. What do you think about remove the catalitıc convector from e46 320d? Someone says pressure is down in low rpm so low torq?
I wouldn’t bother personally, unless you want more noise
If you delete your cat you’ll gain quicker spool on the turbo
Hello, the Ista D link that you have there doesn't work, can you please put a new link?
Thank you, keep up the good work
Unfortunately all sellers have been taken down from BMW😢
Hi George ,another great vid DPF,, What a pain in the arse ,,,never had any problems with my F30 m sport ,,,,upto date ,,watch it play up now ,,lol ,,,,but i had Insignia 2ltr cdti,,once what a peice of 💩 ,that was always in the garage,,,anyway keep em coming mate, stay safe all 👍
bmw s dpf have a life mileage in the ecu normally 250,000km , i have had it before where you need to reset this mileage and it functions correctly
I think the ECU counts the amount of regeneration and once it reaches a pre determined amount it won't regenerate until you replace the filter.
Fixed the issue now: ruclips.net/video/Ff60sMnS5z8/видео.html
You can reset your DPF mileage very easy if that woud be a problem but i don`t think it was.
Great advice. Where can I get an mot with no dpf fitted please because every test station here said they would fail It if removed 👍👍
If I remember correctly the dpf is a serviceable item in this year of bmw.
I think it is mileage/age related.
The software is designed to give a fault even if the dpf is ok or repairable.
Hi George. I've done a DPF gut and a EGR electronic delete on a BMW N47,
PROS: more power, 1L less diesel consumption.
CONS: The exhaust makes a whistle, it blows some black smoke on heavy acceleration and it smells.
My car had DPF+CAT on the same muffler, so when it was gutted we lost the Catalyst function too.
I was thinking if i put an universal catalyst in the middle of the exhaust (my car doesn't have the middle muffler) i can catch 2 birds with 1 stone: reduce the whistle noise from the eaxhaust tip, and reduce the smell and the black smoke.
Do you think it's plausible?
Possibly!
@@GeorgeAusters nevertheless, making all the calculations, a car without DPF that consumes 1L less/100km maybe it's more enviromental friendly than a car with a problematic DPF (almost all).
You should only delete dpf and leave cat in place.
@@harrymoon6060 It is the EGR delete (also illegal in the UK) that causes the biggest harm as NoX gases increase massively. These cause respiratory illnesses and lung diseases especially in young children. So better than a problematic DPF, no, not by a country mile.
The whistle noise is just the turbo when the wastegate moves when it starts it sounds like a jet
Did you reset the fault codes before you tried to regen? I don't think you mentioned whether you did this before the drive. My understanding it it won't even try to regen with fault codes active. Also, it's an mot failure if you remove the dpf.
Hi George we’re do you get the ISTA and plug from please?
Sorry mate the seller was taken down. I will update everyone when he is back up and running👍🏻
Great video, but isn't it illegal to remove it?? - would it pass the MOT without it? I've had similar issues on a 520D... a flush costing around £300 never did anything.
I have a Toyota Auris SR180. 2.2 diesel 2009 with 150k
2yrs ago I got a check engine light..emissions. Took the egr off it was choked SOLID with carbon..took the inlet manifold off choked SOLID. Cleaned them out gave it a service with a oil flush and a carbon clean. Now I do it annually.
as for a regen for the dpf i do a ‘forced’ regen…it takes minimum 10mins. 3rd gear 60mph 3k revs and I set a timer for 12mins. YOUR DOING IT WRONG YOU NEED TO BE IN 3rd GEAR. I have a 30miles stretch of road nearby I go down at 70 normally get up to temp then on the way back do a forced regen. You would not believe what comes out the back it like the car is literally on fire. White smoke like you wouldn’t believe. But after that…she runs like new. Never even a puff of smoke ever no lights on the dash and I give it death. Brilliant car.
It is illegal to remove under Construction and Use regulations.
If you can remove the DPF and have it placed in an ultrasonic bath for approx 48 hrs, this will remove the deposits. This proved very successful on a Vx/Opel Signum 3.0DT we had (the DPF had previously shown as too blocked to regen). The result was a 98% flow rate. The car did meant thousands of miles after this and was still running perfectly when we sold it on. To be fair, the DPF on that car was easier to access, being under-slung, not like the 330d Touring we also had.
Its illegal, it wouldnt pass an mot and you risk a hefty fine of 2000 pounds. Dont do it.
Needs a soaking overnight prior to flush
It's 10k maximum fine...they do pass mot if they are mapped out correctly but I figure it's easy to put the standard dpf on for an mot once a year
Was chap I used to see around telling fibs when he said removing the filter caused his car to fail the MOT. He said when the MOT station logged his car on to the system it told them the car came fitted with a filter. It’s removal they claimed meant an automatic failure.
My Mazda 3 has over 160K and no problems. During a dpf clean the exhaust is much hotter to the hand. Removing a dpf is illegal and your car will fail the MOT. The same for EGR tampering.
I think overall driving style affects the dpf condition, short journeys are just not right for 3 litre turbo diesel cars. Replacing a dpf with a new dpf around 8-10 years into car ownership is pretty reasonable to be honest, it's just not the fun or performance way to be honest!
Well what if i nearly broke my engine since its excessive active regenerations?
The solution is now easy: remove the DPF, straight pipe it, delete dpf (and egr?!) in software and enjoy a proper Diesel
@@harrison00xXx so if it’s costs to be much to get rid of asbestos I can just burn it outside your house ?
@@harrison00xXx completely agree. Get rig of the two items you mentioned and that's most of the headaches gone.
Why do ALL diesel owners need to remove their DPF's? You have not made a case for such. My 6 yr old Mazda 2 skyactivD regenerates quite happily on its own. Had one problem with a sensor, but Mazda fixed it for free outside of warranty. Fine ever since.
I don't think he meant it literal, I think it was more of the RUclips game , of having a striking title that lures viewers in.
My son has a vw passat 2009 tdi 2.0 he has had all sorts replaced it regens all tge time some how its putting diesil in his sump so he is changing engine oil every week he has spent a fortune 3 garages still does the same thing
