As a heavy diesel tech I've learned one thing, you can clean the dpf! There's actually machines that look like a cnc power washer cleaning them, then they bake em out. The issue is what clogged the DPF. Usually its an injector in my world, but every time it wants to blow a bit of black smoke the filter catches it. That's the issue you never get the smoke to let you know. Just my 2 cents but a clogged dpf is a biproduct of an underlying issue! Thanks for the video educating people. I enjoyed it! My guess is its the intake leak, the engine is going to put more fuel in to compensate and make soot.
+1 to this ^. a clogged DPF is usually a symptom of another issue. I had DPF issues with a Holden Cruze 2.0 Turbo Diesel constantly requesting regen and then going into limp mode throwing codes for MAF sensor issues etc. found a leak in the intake piping between the intercooler and the intake manifold, fixed that, did another regen and its been running like a train ever since.
@@numbnutsAU That was lucky then, my friend bought a 2012 Subaru Outback boxer diesel around three years ago with 50k miles on it, we believe the previous owner sold it because of dpf issues as when it started playing up in my friends ownership the garage found the dpf had been cleaned before, they cleaned it again, replaced parts, did a smoke test etc, couldn't find a leak, charged him over £1200 for the pleasure and said that "should" fix it, some time later the symptoms returned, juddering on regen, eml came back on and then went into limp mode so he took it to Subaru who kindly replaced the dpf etc for a considerable amount of money, hopefully it will last another few years!
Martin you need as you know need to repair the faults before it will regen. Needs more than 1/4 of a tank. Check the two pipes of the dpf that go to the pipes are clear? Put an airline down them. Air intake leak, check the intake air flap spindles. Make sure the rods are connected
Martin next time put a plastic bag over one end of the DPF and secure with a rubber band. Stand it vertically and spray a can of Mr Muscle foam oven cleaner in the top, allow to stand for at least an hour and then jetwash it through. It will come out as good as new.
@@gdfggggg Yes oven cleaner. The chemicals that strip all the black carbon like crap from the sides of oven walls and glass doors works perfect on removing the similar carbon like crap from a DPF.
At work we have a £20000 DPF cleaning machine and it’s litterally a massive jet washer. A car pressure washer is more than adequate to flush the soot and ash out . If your pressure sensor is faulty it won’t regenerate.Good on you for giving it a go, I think you should invest in a scissor ramp you can get them to go 6 feet up in the air. Cracking video as per usual.🚙🇬🇧👍
The Dpf won't regenerate by just running with high revs . If you have any engine codes it won't regenerate also if there isn't enough fuel in the tank on some vehicles it won't either . Also if the thermostat is faulty and it's not up to temperature or too hot the ecu won't let it regenerate.One of those reasons could be why it couldn't regenerate when you was trying with you obd tool.. As someone mentioned on this thread get a bottle of wynns dpf cleaner and put it in with the fuel tank . As it's diesel and the fuel is on a return feed to the fuel tank it works quickly . I tried it on a road test with dealer software on a car that wouldn't regenerate and on a 140 mile run it reduced the soot content by 60% according to the dealer software so I can verify it works. These cleaners will only clean out the soot content not the ash as most work by clinging to the soot and lowering the temperature that's it burns off at so normal operation clears the dpf. Check the dpf pressure sensor as that may have fouled up also the pipes first for blockages in case it's an easy fix .. if your not a mechanic when you get a car with a dpf you will be by the time you've sold it 😂
Struth! Lets hope the head didn't warp with all that heat. This sort of thing is why I stick with my old daily driver 1991 F250 4x4 7.3 IDI diesel with 1.34 million kilometers on it. I rebuilt the 5 spd ZF-5 trans in 2018 and changed the diesel pump this year. Other than adding an electric fuel pump it's all original. Sure, it's rusty, but what the hell...
I would've recommended Wynns DPF cleaner solution, dip for upto 8hrs and blast it with pressure washer, since you've gone through alot of effort. Take care 🙂
I’ve had really good results with Forte products, the diesel fuel system treatment and the DPF cleaner. They’re only fuel additives, and for the sake of a tenner a go - it’s worth a try!
The "Air intake leak" fault code refers to a faulty EGR valve , these get crudded up and and are unable to open/close properly . Easy to change and inexpensive . Try cleaning it out first .
Martin, check the swirl flaps for leaks, very common problem on theses engines. Infact I recommend you deflap the manifold, many engines have been destroyed when the flaps break and get sucked in.
When i did dpf on my c250 i jet washed it etc then soaked it in ad blue over night, then cleared fault codes and took for blast down motorway at legal speeds keeping revs at 3.5k for 15miles, no issues since
Why soak it in adblu? It's not a detergent, you might aswell of soaked it in water. Adblu is only synthetic urine, well actually urea which is basically piss.
@@stiggyness1976 a mechanical friend suggested it so i just went with it for the sake of a 10er and my merc been running fine ever since but thanks for the information, i did notice tho after i jet washed it etc then filled over night with adblue it did break down some of the carbon inside as could see the black floating around the top.
I've seen people take DPFs that were absolutely 100% caked and be able to clean them enough to perform a regen with a ye olde Italian tune-up to finish the job. the important part is getting it to flow enough that it doesn't throw trouble codes once ya clear 'em from the ECU, then give 'er a bit of a rag about to let the DPF regenerate unless your scan tool lets you get off lightly and does the regen that way. Most DPFs unless they have more rust holes in their shells than the floorpan of a daily driven '72 Dodge Charger can be cleaned up and reused without much hassle.
I had a problem when the mechanic tryed to do my regeneration with snap on then found out the car needs at least half tank of fuel because it add so much fuel to the exhaust to burn the crud off worth a try?
my dpf was flushed twice and the Fault returned each time after two hundred miles. so I sent it to c s autos pontefract ltd to have it ultrasonically cleaned cost £238. They do it for the local council as well. Done 4 thousand miles now and it has been perfect.
Check the Turbo , it might be at fault , if it leaks oil, then the dpf would get clogged , and a new dpf wouldn't solve the main problem and would get clogged again. Check the turbo shaft for movement , a bit side to side movement is ok, but if it has fawards and backwards movement, you need to get it fixed. Also check the intercooler , if the turbo is bad you might get oil in it
I hope you didn't blow the head gasket on the regeneration test run. I had that happen once, when a plastic water pipe/thermostat broke of and all the coolant leaked out.
Hey Martin, don’t know what amount of fuel was in it but it’ll need over a 1/4 of a tank or it won’t start a regen. Also stick a dpf cleaning additive in the tank and a tank of super diesel. It makes the dpf burn off at a lower temperature.
You can weld stainless steel using mild steel welding wire in your mig welder all that will happen is the weld will rust, I have also welded a Yamaha WR450F titanium exhaust using a mig with mild steel wire when I put that engine in a quad bike
Sure you are on the right track with a regen not happening with fault codes present the scanner is just stopping the regen due to fault codes being present Makes sense the tool stopping you damaging the car IMHO
Sometimes there's latched DTC's that usually the manufacturers computers can clear or run it through a DPF service regeneration or aftertreatment verification Procedure. Usually the engine will derate if it has aftertreatment DTC.
Sort the differential pressure sensor before it gets stuck in re-occuring regen mode and diesel ends up in the sump and blows at the weak points ,hoses first then scanner in diff pressure sensor is it working correctly. hope this makes sense i similar in a hyundai santa fe 2007 Go well keep useing the diagnostic tools they will assist greatly in replacing the defective component, useful sights scanner danner, south main auto and diagnose dan to name a few great coaches in this area kind regards
air intake leak is blocked DPF Code normally had it other week due to a blocked DPF , my customer in the end decided to remove the DPF and map it out the system
@@retrorestore The function of the sensor is to detect fine carbon particles between the air molecules. After a while, the sensor itself becomes contaminated and cannot detect particles. It's not damaged, but it's dirty. Or they can be loose. But many cars do not have the ability to reset and detect the pressure sensor, so when you disconnect it from the cable, the car battery must be disconnected beforehand so that the computer does not send the wrong pulse, when you connect the new sensor, close then turn on the battery. . In most cars you have to give the car 24 hours for the car computer to detect it.😉
@@Pooya-kyani The pressure sensor compares the pressure difference from the inlet side of the DPF to pressure on the outlet side of the DPF. It does not "sense" carbon particles between the air (or other) molecules. The sensor "infers" a clogging DPF when the pressure on the inlet side of the DPF rises above predetermined value point in the emissions software. Lots of ways for the associated tubes and hoses to be defective in this pressure differential based sensor configuration. hoses can crack/split, tubes rust through or clog, etc.
myself did this with an ultrasound water cleaner, I got a fiat with a same engine like this, DPF is the same too, and this done 10 moths ago, and DPF differential pressure as low as like after the cure.
@@MrSnookerballs DPF's when done this way are opened at the top, once replaced on the vehicle you won't see it. DPF's are not needed, once cut out engines run far better.
Air intake leak would cause over fueling which would produce excessive soot which is likely the cause of the blocked dpf in the first place . Definitely carefully check the rubber hoses leading to the differential pressure sensor. Lastly tell the ecu you have replaced the dpf because if its gone over a certain limit it will prevent regeneration unitil you tell it has been replaced ( trick it ) then run a regeneration .
Great video Martin, my guess regarding the regeneration is if its anything like my Saab 93 you would have to use the GM Tech 2 scanner as they share the same engine you can only do certain things with a obd2 scanner. Been looking into getting a Tech2 but there so expensive.
Martin, buy the op-com software for laptop with obd cable. You can pick one up on eBay for £30. Perfect for your age Vauxhall. Did the regen of my signum using the opcom which meant I could drive the car to a suitable garage who then drilled out the dpf and remapped it to 190bhp.
if the oil was low, that may mean the car is burning oil, probably in the turbo or something is wrong with the breather system i would assume, which along with gentle driving and not enough motorway time would block the dpf really quick
A remap is not just for bhp gains it is also used to delete emissions related issues I've been a mechanic and mot tester for 9 years and its only illegal if during mot the tester can prove the dpf has been tampered or cut in anyway if not it will pass its co/emissions regardless so your wrong
If my diesel car or the works van says "Blocked DPF" my best solution so far is to drive for 10 miles at 30 - 50 MPH. After a few weeks of really short journeys a trip to the nearest motorway junction and back after rush hour seems to solve everything.
I work on an industrial site where most of the vehicles are diesel and rarely do a journey of more than two or three miles at a time. DPF issues are a perpetual thing. The accepted solution from the vehicle workshop is to pop on the trade plates and take it for an ‘Italian tune up’ on the dual carriage way. It seems to work!
At least you’ve improved it, shame the scanner didn’t do what it was supposed to do, but perhaps those codes you still have could be causing that. I’ve finally got a filing cabinet, so an oven build will be on the cards soon. Good video 🙂👍
@@retrorestore I went for a 6ft proper heavy duty filing cabinet older one. Should do the job. I’m going to get the set up sorted so it can be as efficient as it possibly can be, so I need the blast Cabinet up and running and the big oven then all should be good👍
On the Bmw 530d I just bought she's had a new pressure sensor. Someone has left the old one in place. Quite a common fault I believe last car I had with depoltion filter was a Volvo was a pain in the Neck mate hope your well and family. Nice job anyway mate.👍🤟
Great vid as always Martin I believe scan tools will not let you do s static regeneration as a safety feature due to high temperature being a fire hazard another thing to check is the egr as they come hand in hand with blocked dpf
Try soaking submerging the software in biological washing powder hot water first to help dissolve the carbon first. Always worth trying to wash it out first :)
My vauxhall zafira 1.6 diesel is bellowing out white white bad, its to do with dpf, does it require a clean out or just a regeneration? What's the make of your regen computer? Many thanks
Really want a topdon scanner just can't afford atm, the recommendation by you sold it to me when you did that video just need that cash for the diagnostic ability boost. Also no longer having a ford Mondeo and having a Citroen seem to need it a hell of a lot more.(not surprisingly)
If you stay away from euro cars the need for a scanner and parts drastically reduces . French is what keeps most independent garages in work lol. Volvo mercedes subaru toyota, nissan (if not a renault rebadged) are brands we don't see too often and do high miles with high reliability. Don't assume new better either, from our MOT statistics 2010 onwards has a failure rate 70% higher than 1995 to 2010 models . The quality of newer car components is quite simply awful and that even worse because of system complexity that ideally needed better quality to be reliable in vehicle environment conditions. The amount of expensive just out of dealer warranty cars we see for wacky electronic and emission diag work is frightening and some of the fix costs are even more frightening . Basically if you buy older and buy wise you won't have much need for a scanner or spare parts . Buy main stream junk and you got ballache and bills as long as you can stick it out ...
@@jackrussel853 subaru diesel is best avoided mainly due to engine crank failure (the diesel is a known major lemon and written off by crank failure) but also dpf, glow plug issues and injector learning software that doesn't seem perfect software logic. Modern diesels are awful for low mileage as DPF requires long runs, personally I would avoid any euro5 or earlier dpf equiped diesel as they are nothing but expense keep emissions and running usable & do sweet FA for environment ..
@@mrb1864 Agreed, i tried to put him off buying it but after many years of deciding what to replace his 96 Peugeot 106 diesel with that he owned for eighteen years he'd decided on that and made up his mind, he will not buy a petrol although you need to be doing around 15k miles a year to make it worth owning a modern diesel i believe, I thought it was the earlier models that suffered the crank failure and it had been eliminated for the later model, i won't bring up the other issues with him as he gets annoyed :)
@@jackrussel853 Crank failure never fully cured, they redesigned crank and block a few times along with other changes to torsional/harmonic dampening, dmf and even compression ratio changes but it still happens given enough time . We had clean 2013 in the yard last year that went to scrap (had a few from 08 to 2013), owner didn't have funds and it really not worth chucking 5K at engine replacement when you know they faulty by design plus you need dpf in A1 order and any other pre engine failure niggles which all extra high costs get worthwhile end result .. The resale value is rock bottom on them as well, is a shame and so wasteful but that modern engineering . Wait for the hybrids, we seeing HUGE amount of issues on cars virtually new & lot of it not totally fixable as bad by design and some of these are 40K new vehicles ! Quite simply if want reliability and low cost avoid anything newer than 2005 and diesels pretty pointless these days, most people won't see much benefit as diesel prices high and you have do your homework and buy perfect era diesel with no dpf if want long term no hassle, once in garage for dpf egr issues you blown anything saved in fuel cost and loosing plus the time waste and stress of it . People really need learn more and buy smarter and refuse buy poor engineering & nonsense environmental concepts .
Let’s face it, buying a diesel with dpf is just stupid. I’ve also done this mistake once. You either buy a non dpf diesel, or get a petrol. Regardless of technology and brand, its gonna take its pants down sooner or later. Period.
i would ve blocked one end of dpf and filled ir with petrol that would dissolve all the soot an carbon let it soak for an hour slosh the petrol about shake it now and again then jet wash it inside would be sparkling clean like new
Well if that cable tie has lasted that long then you certainly got value for money from it. If you have any problems with Halfords Advanced tools (no matter how old they are) take it back to any Halfords for a free replacement, no questions asked.

If the pressure sensor is faulty ( via a split in the pipes or the sensor itself) then it won't regen.... Eventually resulting in a blocked up DPF if left un-fixed 😉😅
do you think heating the dpf with a torch while the car is running would help any? I think that's the goal of the regen mode to heat the internals of the dpf box or remove it from the car and set up a strong vacuum on the box while heating it removed from the car?
@@sleepingwarrior4618 when I worked for Halfwits replacement parts would need to be taken from the shop floor or ordered through Cobalt innovations, (many staff didn't know how to do this 🤬).

On vw Audi cars when forcing a regen it requires 90c engine temp, quarter of a tank, it then sits at around 1400rpm for approx 25 mins. You can see dpf clearing on the screen. 645c it gets too so cooling fans run too
Brings back memories of washing my Suzuki X7 pipes out with Caustic soda, never had much success with that, nice try Martin lets hope that's done the trick.👍😀
@@retrorestore look at how much has squeezed out of the joint externally, safe to assume the same amount has squeezed out internally. This will now be blown into your freshly cleaned DPF… Not great.
Vauxhall were relatively early fitting dpfs and seem to have no rhyme or reason. All zaf b diesels have them,twintop astra and vectra/signum if auto and vectra if estate as well. Odd really but that's vauxhall.
Martin. Halfords used to do an exchange on tools as they had a lifetime guarantee. But apparently changed their replacement policy. They require proof of purchase which is a joke because any receipt would fall apart before tools. Air intake leak could be swirl flap bar come off.

The sensor "infers" a clogging DPF when the pressure on the inlet side of the DPF rises above predetermined value point in the emissions software. Lots of ways for the associated tubes and hoses to be defective in this pressure differential based sensor configuration. hoses can crack/split, tubes rust through or clog, etc.
myself did this with an ultrasound water cleaner, I got a fiat with a same engine like this,
DPF is the same too, and this done 10 moths ago, and DPF differential pressure as low as like after the cure.
Interesting video, enjoy your vacation. We just came back from a trip to the Rocky Mountains. Much enjoyed ! 😎
Cut the DPF down the seam, pull apart and remove the innards with an air chisel. Weld it back up.
No more blocked dpf..
and illegal if spotted when doing an MOT
@@MrSnookerballs DPF's when done this way are opened at the top, once replaced on the vehicle you won't see it. DPF's are not needed, once cut out engines run far better.
@retro restore Martin how about that cable tie around that coolant pipe my jaw dropped with astonishment another good one 👍
Air intake leak would cause over fueling which would produce excessive soot which is likely the cause of the blocked dpf in the first place . Definitely carefully check the rubber hoses leading to the differential pressure sensor. Lastly tell the ecu you have replaced the dpf because if its gone over a certain limit it will prevent regeneration unitil you tell it has been replaced ( trick it ) then run a regeneration .
Shovel hands. I feel your pain there, they never fit anywhere!. Love them little lifts you've got, look really handy.
Thanks 👍
Great video Martin, my guess regarding the regeneration is if its anything like my Saab 93 you would have to use the GM Tech 2 scanner as they share the same engine you can only do certain things with a obd2 scanner. Been looking into getting a Tech2 but there so expensive.
I would defiantly put some dpf cleaner in the tank, it's the only thing that keeps the light off our dv6
Martin, buy the op-com software for laptop with obd cable. You can pick one up on eBay for £30. Perfect for your age Vauxhall. Did the regen of my signum using the opcom which meant I could drive the car to a suitable garage who then drilled out the dpf and remapped it to 190bhp.
I have thought about it, Is it MOT legal though?
@@retrorestore If the car was registered before 2009 then yeah it'll be fine
if the oil was low, that may mean the car is burning oil, probably in the turbo or something is wrong with the breather system i would assume, which along with gentle driving and not enough motorway time would block the dpf really quick
Get a remap mate and be done with dpf issues for good
a remap is to boost bhp and wont make any difference to the dpf. a dpf delete is what you mean and the innards will have to be removed. illegal.
A remap is not just for bhp gains it is also used to delete emissions related issues I've been a mechanic and mot tester for 9 years and its only illegal if during mot the tester can prove the dpf has been tampered or cut in anyway if not it will pass its co/emissions regardless so your wrong
If my diesel car or the works van says "Blocked DPF" my best solution so far is to drive for 10 miles at 30 - 50 MPH. After a few weeks of really short journeys a trip to the nearest motorway junction and back after rush hour seems to solve everything.
I work on an industrial site where most of the vehicles are diesel and rarely do a journey of more than two or three miles at a time. DPF issues are a perpetual thing. The accepted solution from the vehicle workshop is to pop on the trade plates and take it for an ‘Italian tune up’ on the dual carriage way. It seems to work!
Intake air leak can also be swirl flaps
Clear all fault codes after fitting back the DPF then take it for a run and see if the codes come back.
At least you’ve improved it, shame the scanner didn’t do what it was supposed to do, but perhaps those codes you still have could be causing that. I’ve finally got a filing cabinet, so an oven build will be on the cards soon. Good video 🙂👍
Look forward to seeing you get going with that Luke.
@@retrorestore I went for a 6ft proper heavy duty filing cabinet older one. Should do the job. I’m going to get the set up sorted so it can be as efficient as it possibly can be, so I need the blast Cabinet up and running and the big oven then all should be good👍
Great work and thanks for sharing this with us take care
On the Bmw 530d I just bought she's had a new pressure sensor. Someone has left the old one in place. Quite a common fault I believe last car I had with depoltion filter was a Volvo was a pain in the Neck mate hope your well and family. Nice job anyway mate.👍🤟
Cheers Ali, back to the UK tomorrow.
Worst thing I ever did fitting DPF filters to diesels totally ruin them
Hope you get it sorted soon Martin 👍👍👍👍
Why dont you drill 3x 10mm holes through the core of the dpf
Great vid as always Martin I believe scan tools will not let you do s static regeneration as a safety feature due to high temperature being a fire hazard another thing to check is the egr as they come hand in hand with blocked dpf
Try soaking submerging the software in biological washing powder hot water first to help dissolve the carbon first. Always worth trying to wash it out first :)
DPF, not software! Stupid phone auto correct ball locks...
My vauxhall zafira 1.6 diesel is bellowing out white white bad, its to do with dpf, does it require a clean out or just a regeneration? What's the make of your regen computer? Many thanks
Really want a topdon scanner just can't afford atm, the recommendation by you sold it to me when you did that video just need that cash for the diagnostic ability boost. Also no longer having a ford Mondeo and having a Citroen seem to need it a hell of a lot more.(not surprisingly)
If you stay away from euro cars the need for a scanner and parts drastically reduces .
French is what keeps most independent garages in work lol.
Volvo mercedes subaru toyota, nissan (if not a renault rebadged) are brands we don't see too often and do high miles with high reliability.
Don't assume new better either, from our MOT statistics 2010 onwards has a failure rate 70% higher than 1995 to 2010 models .
The quality of newer car components is quite simply awful and that even worse because of system complexity that ideally needed better quality to be reliable in vehicle environment conditions.
The amount of expensive just out of dealer warranty cars we see for wacky electronic and emission diag work is frightening and some of the fix costs are even more frightening .
Basically if you buy older and buy wise you won't have much need for a scanner or spare parts .
Buy main stream junk and you got ballache and bills as long as you can stick it out ...
@@mrb1864 Sadly my friends 2012 Subaru Outback diesel has been very unreliable even though the mileage is low, i'll stick to my 2001 Vauxhall Astra.
@@jackrussel853 subaru diesel is best avoided mainly due to engine crank failure
(the diesel is a known major lemon and written off by crank failure) but also dpf, glow plug issues and injector learning software that doesn't seem perfect software logic.
Modern diesels are awful for low mileage as DPF requires long runs, personally I would avoid any euro5 or earlier dpf equiped diesel as they are nothing but expense keep emissions and running usable & do sweet FA for environment ..
@@mrb1864 Agreed, i tried to put him off buying it but after many years of deciding what to replace his 96 Peugeot 106 diesel with that he owned for eighteen years he'd decided on that and made up his mind, he will not buy a petrol although you need to be doing around 15k miles a year to make it worth owning a modern diesel i believe,
I thought it was the earlier models that suffered the crank failure and it had been eliminated for the later model, i won't bring up the other issues with him as he gets annoyed :)
@@jackrussel853 Crank failure never fully cured, they redesigned crank and block a few times along with other changes to torsional/harmonic dampening, dmf and even compression ratio changes but it still happens given enough time .
We had clean 2013 in the yard last year that went to scrap (had a few from 08 to 2013), owner didn't have funds and it really not worth chucking 5K at engine replacement when you know they faulty by design plus you need dpf in A1 order and any other pre engine failure niggles which all extra high costs get worthwhile end result ..
The resale value is rock bottom on them as well, is a shame and so wasteful but that modern engineering .
Wait for the hybrids, we seeing HUGE amount of issues on cars virtually new & lot of it not totally fixable as bad by design and some of these are 40K new vehicles !
Quite simply if want reliability and low cost avoid anything newer than 2005 and diesels pretty pointless these days, most people won't see much benefit as diesel prices high and you have do your homework and buy perfect era diesel with no dpf if want long term no hassle, once in garage for dpf egr issues you blown anything saved in fuel cost and loosing plus the time waste and stress of it .
People really need learn more and buy smarter and refuse buy poor engineering & nonsense environmental concepts .
Let’s face it, buying a diesel with dpf is just stupid. I’ve also done this mistake once. You either buy a non dpf diesel, or get a petrol. Regardless of technology and brand, its gonna take its pants down sooner or later. Period.
Have a Great holiday Mart & Sharon.
Baz.
Just got back Baz after 3 weeks away.
i would ve blocked one end of dpf and filled ir with petrol that would dissolve all the soot an carbon let it soak for an hour slosh the petrol about shake it now and again then jet wash it inside would be sparkling clean like new
Well if that cable tie has lasted that long then you certainly got value for money from it.
If you have any problems with Halfords Advanced tools (no matter how old they are) take it back to any Halfords for a free replacement, no questions asked.
Have a good holiday Martin.
Last day today, A great 3 week break
Mate if it doesn't work I would just smash it out and remap it 🤘🤙👊
Nice 1 Martin 👌👍
The reason it blocked is you HAVE CODES.... You can't regen with codes especially those 2.... It will clog again if you don't fix them
Yes I know.
Air intake leak. My rad was knackered
Martin Halfords advanced have a lifetime guarantee so you can just take it in and they should exchange it there and thee joy your holidays
Yes Malc, i've done it a few times already.
Emission laws are killing diesels.
Great vid but I'm sure that will be sorted soon
Martin use barrier cream instead of gloves much better
As you run mostly GM vehicles I would seriously look at getting a GM tech 2 clone from China.
gm mdi 2 is the one to get the tech2 handheld old hat now
@@AlanAnsell op com is the tech 2 Chinese clone
There is no Tech 2 clone. Its a very expensive bit of kit and like said it's handheld device. It does all the programming and installation modes on Vauxhall Opel cars.
Its VauxCom and OpCom that's cloned.
@@gareth121astra opcom is a clone of vauxcom Chinese tech 2 is a clone of tech 2 but for what he was doing a £20 opcom might be better then a £150 clone tech2
all 3 units are clone
If the pressure sensor is faulty ( via a split in the pipes or the sensor itself) then it won't regen.... Eventually resulting in a blocked up DPF if left un-fixed 😉😅
don't buy a new universal joint, just use a centre punch on the pin to expand each end to stop it sliding out.
It has a lifetime guarantee Malcolm so I can change it free of charge.
@@retrorestore depends on their definition of 'lifetime' 😄
@@malcolm6951 I've changed a few things in my Halfords Advanced set and they exchange them every time with no need of proof of sale.
dpf re grn need to do 50mph plus for a bout 30min drive with no stoping to do a full regen
Halfords Advanced have a lifetime warranty so take it back and they will give you a new one.
say hello to merlin from me....great video...
do you think heating the dpf with a torch while the car is running would help any? I think that's the goal of the regen mode to heat the internals of the dpf box or remove it from the car and set up a strong vacuum on the box while heating it removed from the car?
Not sure bud.
Good video. Do you have a link to the screw lift you use?
Here's the link amzn.to/3CCQvhC
Halfords Advanced tools are covered by a lifetime warranty, no need for the receipt 👍🏻
They often don't have the part you've broke though. And make it difficult to get it to desuade you from getting it swapped.
@@sleepingwarrior4618 when I worked for Halfwits replacement parts would need to be taken from the shop floor or ordered through Cobalt innovations, (many staff didn't know how to do this 🤬). I believe that the process has changed, however I will find out the new process for you to help in the future 👍🏻
@@sleepingwarrior4618 okay the new process is to order from Head Office. Just remember your rights, like for like, otherwise the life time warranty is "Not fit for purpose" and that is the KILLER phrase in retail. Hope this helps 👍🏻
On a Navara the light can be turned off but it appears the fault stays in the ECU because its still in a form of limp mode. Any suggestions.
Clean the dpf bud so the ecu see's the correct pressures from the sensors.
Good old Signum, i love my Vectra 1.8vvt not the most power punch but never really had driveability issues apart from a leaking exhaust
On vw Audi cars when forcing a regen it requires 90c engine temp, quarter of a tank, it then sits at around 1400rpm for approx 25 mins. You can see dpf clearing on the screen. 645c it gets too so cooling fans run too
Brings back memories of washing my Suzuki X7 pipes out with Caustic soda, never had much success with that, nice try Martin lets hope that's done the trick.👍😀
Italian tune up on the motorway
Never want to use any kind of sealant on exhaust flanges in front of a cat or dpf..
You don't give a reason.
@@retrorestore look at how much has squeezed out of the joint externally, safe to assume the same amount has squeezed out internally. This will now be blown into your freshly cleaned DPF… Not great.
@@ninjabob8170 there was sealant on it originally and there was no sign of that happening so I assume not.
Quite rare for a 150 cdti to have a dpf sure it was only certain models
It was standard on Signum, Vectra Estate , Astra Estate and Astra Convertible.
Vauxhall were relatively early fitting dpfs and seem to have no rhyme or reason. All zaf b diesels have them,twintop astra and vectra/signum if auto and vectra if estate as well. Odd really but that's vauxhall.
Help Sharon with the bin Martin lol !!!!
Good one Martin once you get them 2 fault codes cleared then it may let you do the DPF regeneration
If there's a fault code it won't let you do a regeneration
So many people use the wrong oil for dpfs.
Wrong oil?
@@paulkazjack As in not low ash low oil.
Martin. Halfords used to do an exchange on tools as they had a lifetime guarantee. But apparently changed their replacement policy. They require proof of purchase which is a joke because any receipt would fall apart before tools.
Air intake leak could be swirl flap bar come off.
DPF EGR is the worst thing invented for Diesel engines nothing but trouble
