Every week we get many cars in the shop with diesel particulate problems ( DPF ) so i though id make a super quick video to name the most common faults.
Its not just the VW / AUDI / SKODA / SEAT Brands that suffer from DPF problems so these tips are universal across all brands.
For blocked DPF's we offer on car DPF cleaning, for more info click the link at the top.
WHAT IS A DPF?
The Diesel Particulate Filter is in the exhaust system of all diesel-powered cars sold new since 2009. It is a vital component that is designed to enable cars to pass increasingly tough emissions legislation. The DPF’s job is to trap the particles and thereby prevent harmful smoke from being pumped into the atmosphere.
HOW DOES A DPF WORK?
Like any filter, the DPF will gradually get clogged with the soot that it traps. However, the car is designed to clean it by heating this residue up, turning it to ash and expelling it. This happens about every 300 miles, either when you travel at motorway speed, or because the Engine Control Unit initiates what’s known as regeneration by raising exhaust temperatures artificially.
WHAT PREVENTS NORMAL DPF REGENERATION?
The wrong type of engine oil - check your handbook
A problem with the fuel system or Exhaust Gas Recirculation (EGR) causing excess soot.
A warning light on the dashboard or a diagnostic trouble code stored in the engine management system.
Going over the recommended service interval
If the vehicle uses Eolys™ additive, a low level in the tank can prevent regeneration.
Low fuel level - generally less than a quarter of a tank - will prevent active regeneration taking place.
Ignoring engine faults, Wrong or dirty oil and lack of servicing are popular reasons for DPF problems but THE MOST popular reason we see time and time again is running the car low on fuel frequently! The car needs above 1/4 to a 1/3 of a tank of fuel for the DPF system to function properly. No fuel no regeneration - simple!
If your having problems with your DPF give us a call on 01253 821971 or mail volksworkshop@hotmail.co.uk
Although not directly connected to this video, but my point highlights the point of why DPF's were introduced to the car..basically to cut down pollution..right?..but we are being told in this video and many others, and also from various Mechanics to get out and boot the car on a regular basis and maybe 15 to 20 mile drive up and down the
Motorway..thereby doing unnecessary journeys to solve the DPF issues.
So basically we are putting more pollution out, and defeating the purpose of the DPF theory..its Nuts!!!
Exactly what I was thinking! It's so backwards it's unreal. Remove and remap has got to be the way!
Specifically, its purpose is to reduce the amount of soot getting into the air, and it does at least do that. In terms of health for living things in cities or near major motorways, the soot/similar particulates is one of the worst offenders.
You are right that you end up putting out some additional CO2 from this, though.
I have an audi A6 with the 2.0 tdi ultra, the really annoying thing is that when it starts an active regen there is no light to tell you. First time you know is when you switch engine off and the fans are running and you smell the burning soot. There should be a light to let you know so you can let it finish the cycle before switchingengine off, almost like they designed it to fail.
Recently bought a caddy and second week In I’ve noticed the fan running and burning soot smell. If this is the case, do you start engine so the active regen can do its thing?
@@rahaulmiah yes once you notice it doing that turn engine back on you will notice it will idle at a slightly higher revs and the start stop function (if applicable) will stop working. I just used to sit and hold the revs at about 2000 rpm for around 5 mins or take it for a blast and once the start stop function came back I knew it had finished the cycle.
@@macky4074 thanks for the info. It did again tonight after I got back from work and thats an hours blast on the motorway. Always thought active regen’s kick in usually after short drives?
@@macky4074 If your goal with increased RPM is to increase temperature in DPF, then doing it while standing in neutral will do basically nothing. Engine has to be significantly loaded in order to use more fuel than usual - that will increase DPF temperature and possibly assist in cleaning soot. Basically you have to drive, ideally, uphill. However it still might not do any difference, as active regeneration process adjusts fuel post-injection according to the temperature readings from DPF sensors, trying to hold ~600 °C during the process anyway. You can see those figures in action with VAG DPF application and decide for yourself do the driving style during active regen changes anything (in my car, very minimal or nothing).
If the DPF regeneration does not work below a certain fuel level this should be mentioned in the user manual. And with the same level of attention like the oil level. As this is vital for the whole engine system. And this system is a major one. The car will not work if the DPF does not work. It's the same as oil level, coolant level, brake fluid level. This is not a window cleaner fluid or a "blinker fluid".
Do you really need your car manual to tell you to fill your car every while and not driving with 5 liters of fuel left?
@@songoku7915 No but this requires a 1/3 of the tank. So 15 to 25 litres is a lot. And this is above the reserve. In my car when I'm driving to the reserve I can get another 2-300km for the last third. The system in my car regenerates every ~450km or sooner even if the threshold of soot is not reached. So the manufacturers decided that 450km is enough. Frequently adding 250km over that can lead to a premature damage. A lot of city driving cars that have their DPF's changed at 45 000km filled their tank with ~20l when they reach the reserve. Once a week. What I'm saying is that if the owners have this habit they are not aware of the damage they are enforcing to the system.
@@teovm you're fine. My Yaris regenerates every 140km and i m planning to get it washed or something... Having low fuel level can cause also problems to the fuel pump as well as cause bacterial growth where the fuel cleaning additives don't reach. I always top up with fuel at about 2/4 or in the worst case scenario at 1/4 but i never wait to see the light. Do you gain money by emptying the fuel reserve? You need then more money to top up the fuel.
Thanks for the tip about low fuel...I tend to see how far I can go on a tank. I’ll make sure I don’t run it so low from now on.
No problem James, sometimes these little things can help, like a said if you know you dont know 😀
@@VolksWorkshop same here and thanks, I'm always trying to get better mileage as a little personal experiment but in the long run will likely cost me more ...2014 1.6 idtec civic , last few days after reaching optimal temperature I now drive normally and never brim to empty...subscribed
And the AUX heater for VW diesel needs 1/4 tank of fuel to work or be diagnosed. I didn't know about the DPF so this is a lesson for me here. Thanks for the tips.
@@VolksWorkshop how does it make sense that under a third of a tank makes any diff from 10 percent could ui explain that
Thanks for a great video!
I am tempted to drill a hole somewhere next to the O2 sensor big enough for the nozzle to insert and spray the foam without messing with the sensor. Just have to figure out how to plug the hole!
Just not sure about how much pressure is inside the system.

I was moving my van up to the garage doors and back daily to prevent anything from getting stolen out of my garage. A warning sign came up, now I never run the van without getting the engine hot before shutting it off. Warning sign gone, van back to normal. All I was doing was sooting it up without the chance the van could burn the soot off.
Any tips on unclogging the filter once it is? Any additive to use? Or is this a repair that has to happen?
dont need to worry about your dpf if you delete it with the egr
Wow low fuel - who knew. I've just failed the MOT on emissions 😪😪 Going to strip the EGR and run some Wynnes Emission Cleaner to try and get a pass. Any thoughts on using a DPF cleaner like Wurth?
I’ve used the Wurth product in the past and it worked ok definitely wurth a go 😄
Forcing a regen on a motorway, does the speed matter or is it just the rpm? If I do 3000 rpm at only 50 mph - will that work?
Morning, I’ve got a Passat estate 170 sport it’s a 2006 and it stinks when sat in traffic on tickover. Is this the dpf getting blocked? The light came on the other day but a drive down the motorway in 4th at 70mph cleared it.
My t5 had the dpf regen mapped out by previous owner , any ideas how to clean without removing it
Is it true that now my dpf light, glow plug flashing light, and engine light are all illuminated my caddy will definitely not do a regeneration?
I’m using snap on Zeus scan tool to regen, scan tool shows all temp sensors working but when I try to parking lot regen scanner shows -50 for temp after dpf. Anyone know why?
As you said in the last tip ; is it advisable to drive on motorway with low speed gear ? Like 4 ? On 60 or 70 mph ? Is it true that will help ?
what would you say is a suitable run to help clear it...does it need to be a motorway run with revs at 2k or can normal driving do the job on local road i.e stop start and dual carriageway mixed
Between 3-4k rpm for 15-20 mins
Manual indicates between 2k and redline. So this would typically mean you would want to (if your car has it) engage the semi-"manual" gear shifting mode and just manually keep it in 4th or 5th gear instead of the 6th it would usually go to for highway driving.
Nice one excellent vid I was trying to run one on farts I'll get some fuel first thing tomorrow 👌
I also have a problem with the dpf filter in the sense that due to the low temperature outside the filter it does not reach a temperature higher than 250 degrees and regeneration cannot be done, I did forced regeneration while driving with the carista and in vain that the ash still does not fall from the deposited filter at this moment I have 27 grams of deposited ash, what can I do in this case?I want to mention that no car error code appears on the tester
Sounds familiar. For this issue i use a ‘DPF cleaner’ meant to be put in the fuel tank along with a full fill up. This additive should lower the burning temperature of the soot. It is then supposed to be like a ‘1K regen ride’ after which the DPF should have lost a significant part of its soot deposit. I don’t do any measurements, so I can’t check if it is really working. But the warning light never came back since that one time months ago.
@@kitesupskate1456 Name of DPF cleaner please. Replaced entire exhaust, multiple re-gens, & the damn light stays on. thx b
Had my 2015 Tdi Jetta for 3 years and always fill up on a completly empty tank. (1000 kms/ tank which is my weekly hwy commute) have not had any issues with the dpf. Not sure if the highway driving offsets the empty tank concerns??
DPF blocks when you do a lot of short distance drives, or drive in the city (i.e. making lots of frequent stops). Highway driving should help with DPF to go into regen and clean itself out.
Tell me one reason not to put fuel at least when it's at 1/4.
all the sediment at the bottom of your tank will go through your system inc injectors, these are 650 quid each and there's 4.
Since apparently oil age/mileage can influenced it, it may also be that you are just simply getting oil changes properly and this helps. Also, in my case, I didn't start seeing the light for the first time until my car was 8 or 9 years old (its a 2009 model). Since then, it just came on again recently and I think this time I will probably need to get it properly cleaned.

I've had many diesels and only driven them round town , the key is to not pootle about at low revs , drive it hard and under load when possible, use the torque it was built to use and you will be ok .
I have an insignia vx line diesel and use it on fairly short trips but drive it hard enough and no issues so far (touch wood) and it’s chipped
Starting a new job soon. Gonna be doing a load of motorway commuting. Was looking at 2.0 patrols. Don’t know what I was thinking. The vw TDI seems like a brilliant engine for long commutes
I heard somewhere someone suggesting to keep the rpm below turbo action (around 1,300 rpm in a VW 2.0 tdi) to avoid turbo turbine cool off the dpf. Do you think is valid?
@@jestruck during regeneration drive on about 1800-2200 rpm and you'll be fine. The 3000 rpm reving is indeed a myth.
Love your videos I have a 2014 Volkswagen Jetta tdi does this car have a water separator that needs to be drained every once in a while?
Can it be programmed off on the mk5 2.0tdi without removing the dpf.
No smoking. Only light I occasionally get is turbo boost pressure not detected p2262 any ideas ? Sometimes it bogs on throttle pressure or changing gear etc
The way in which low fuel causes the diesel particulate filter(DPF)(Soot Trap) to not work, was not explained well. Yes, the part about the DPF cleaning system needing "extra fuel" was there, but if the fuel is there in the fuel tank, it's presumably available to the system. So I'm guessing the car's fuel supply monitoring system is preventing supply of the extra fuel to the DPF because it is trying to save fuel when the fuel tank is less than one quarter. In that case, taking the "old girl" for a run to clean out the DPF would not work. On the other hand, good fuel economy occurs at highway speed, so the system should "know" that, and take it into account.
Hey. Does anyone have an idea if its normal to smell exaust /soot smell on cold start with vents on or when you stop in traffic? Does it have anything to do with dpf regeneration? Beacause i have a seal changed bettween dpf and turbo, but that smell still comes when the vents are on. Some one can help maybe had the same issue? My car is vw golf mk6 2.0 tdi 2009.
Have same issue on my Passat, have you determined the cause?
Top tips
Would you share thoughts on dpf delete?
My 2008 Passat estate dpf light is on and has gone into limp mode. Any suggestions??
Great Video. THANKS! Question about the oil. 2015 2.0, been using 5W30 Pennzoil Euro L, some say its ok for the DPF but I'm not seeing the VW 507.00 spec on jug. I bought 2 last year and ready to do an oil change. Any help here?
Unfortunately , no motorway near my house , all roads are 20 miles speed limit. Can I just press the gas for 20 minutes 3000rpm ? Will it work?
yes you can mate, 2600 - 3000 rpm is good for 20 , 30 minutes... and change the oil with fresh 5w30 507.00 low sap oil EVERY 12000 KM

Thanks
Yup,just gear down and burn those puppies
The DPF light comes on with ignition for the last couple of days (this was not
the case previously), but as soon as the engine starts it goes off, should I be
concerned? It goes off together with the glow plug light. What should I do
about this?
It never came on while I was driving, but I'm concerned since this only
started happening a few days ago and I would like to avoid a possible
problem.
I have the exact same problem as you now ..any help please
@@3arbiii897when my glow plug and dof light came on it started smoking and come to find out the dpf was clogged and turbo needed to be replaced. Luckily was under warranty
Any idea why my 2014 Vw Passat TDI gets great 40mpg Freeway but only 20mpg city? (Auto trans)
Thank you mate now I know what I'm doing wrong I shouldn't have many more problems I knew low fuel wasn't good for diesel but I didn't know how low before it struggles
That intro is way too loud. Especially with you whispering afterwards.
Great tips man , I've a 2019 Octavia 3,I've it two weeks , i1.6 TDI , and when I turn off the car , and lock it , the fan keeps running for up to 15/20 mins ??? Is that normal ???
That means that you interrupted an active regeneration. The fans are running to cool down the engine bay. Easy way to tell in TDI's is to pay attention to the idle rpm before you shut it off. If the idle is at 800 like it normally is then it might not be in regen. If it's at 1000 rpms or above then it's definitely in an active regen. The fan running at top speed is also a tell tail sign, although if ambient air temps are low, the fan might not always run. One the most prominent sign is to listen for a hissing noise coming from underneath the car. While in an active regeneration, the DPF is essentially acting as a blast furnace to convert all stored carbon soot into CO2 and water vapor. This fire will create an audible hiss. Lastly, there is a recognizable smell that is produced during regen. It smells a bit like burning rubber. If you can smell that then it's another tell tail sign. As a warning, you should avoid shutting the car off while it is going through this process because of the temperatures involved. During regen, the DPF is already at an extremely high temperature (400-600 degrees Celsius). Shutting down at this temperature can negatively effect the longevity of your turbocharger, catalysts downstream in the exhaust, and the DPF itself. The DPF is made of cordierite which can resist extreme temperature changes to a degree. However, given enough neglect the DPF will crack internally leading to a failure. I have learned from my mistakes while owning a Jetta 2.0 TDI. Everything that this man says in his video is critical to maintaining the health of your DPF as well as what I have said about being able to recognize a regen. Clean air is better for all of us but busting out your wallet to consistently pay for parts is not always good for you. I wish I could say more to you on this subject but my comment has become grossly lengthy. Either way feel free to ask any questions and welcome to the TDI gang.
It is worth noting that it IS possible for the fan to break too. This happened to me (car was about 10 years old at that point) and the fan just stopped turning off, ever. Leading to the battery dying, being replaced, dying again, and then me just getting it jumpstarted and going straight to the dealer to get it fixed (the first time the battery died, I thought it was just since it was a few years old and it was getting colder out).
Might be an uncommon issue, but definitely take a serious note if it ever seems to run for like a whole hour after you turn off the car.
Same as my Aux heater won't work or can't be diagnosed unless 1/4 tank of fuel.
Wholesome helpful bloke. You have my upvote!
My touran 2.0 tdi 2009 every weak do dpf cleaning during cleaning exaust sound changed what is the problem ?
Did you service your car on time? ( buy good engine oil, clean EGR valve)
1- find out why getting block in first place?
2- remove dpf filter and send it for professional cleaning. Remember regeneration not working for longer.
Has anyone got the 1.5 petrol automatic and is it any good, I've heard about kangaroo-ING and burning oil?
My car just had engine management light come on an dpf particular warning sign come can you help me please I well take on motorway I saw your video thanks
Take it on motorway keep rpm between 3-4k for 15-20 mins
Cheers mate great video how many miles should the once a week stretch the car be ?
id say about 30 miles from when the engine is 90 cent oil temp.Done this the other night 5th gear 2000 revs 5th gear.
Unfortunately this advice is just not enough. I have a TDI Golf and I take extremely good care of it. Oil is changed with factory VW oil before 10k miles, fuel filter changed with factory filter, and I keep my fuel over one third tank ALWAYS, not only to avoid clogging my fuel pump with dirty diesel gunk and sediment that falls to the bottom, but also to avoid harming my fuel pump. The problem is that any TDI cars still on the road (at least in the USA) were retuned (timing retarded significantly) in order to burn off more NOx and pass local emissions. Not only the EGR valve but also the particulate filter needs to be regularly cleaned on many cars. I already tried the Lucas Diesel fuel additive specially designed for diesels, and also a computer assisted burn and it did not work. In many cases, without retuning the car, the particulate filter has to be flushed.
Wow great insight. By retuning you mean to correct the timing to original spec?
Soild advice, thank you !
Mega top TIP if you do
A to B driving don't buy one with a dpf avoid it will just give you grief...
Hey quick question, in my 2012 Jetta tdi it’s giving me codes p2002 and p0401. I know that oil change is due pretty soon, so could that be the problem?
Its your egr cooler.99% sure. If you see a bit of white smoke in traffic,your cooler is leaking.
Just had the same codes recently and cost me $4000 to fix 😭. Had to replace dpf and egr valve plus 2 glow plugs on top of everything…sheesh
AVOID DPF BLOCKING.....either delete the DPF, or buy an MK4 or earlier TDI...problem solved
Mk5, I have 6 of them, non of them have problems with dpf, 1.9 not the later 2.0
Good lad enjoyed the video could you do .a video on how to clear the ash .from dpf ?
Thank you .
kinda makes me regret divorcing my German diesel mechanic.
Lol me too!!
Good tips.
I have a vw tdi, it's burning excessive fuel and feels low on power, clogged like it won't take acceleration smoothly .
my 2015 golf tdi has 300,000 miles on it and has started throwing the DPF Regeneration Frequency trouble code. Quick driving not going to solve this one. I didn't see anything useful or helpful about this video. Mine gets "spirited" driving everytime I'm in the car
Did you fix the issue?
At 300k prob needs a new one. Nothing lasts forever. Me… gave diesels up years ago
THNXS BIG!
Thanks lads did not think low fuel
Good informative video...may thanks
Very helpfull many thanks
Brilliant mate thanks for this 🤝
My cars DPF was nearly full, it's only covered 8300 miles , one of the exhaust pressure sensors , the one before the DPF was faulty, I'm not mechanical minded can you explain why a faulty sensor would cause the DPF to fill , many thanks
There are two pressure sensors on a DPF - one before and one after the filter. The cars engine computer (ECU) is able to determine how full the filter is by monitoring the difference in pressure readings between the two sensors... The greater greater the difference in pressure - the more the flow of exhaust is restricted by the soot in the filter. If one sensor isn't reading correctly, the computer doesn't know how full the filter actually is, and it won't initiate a regeneration cycle. This can lead to an overly filled, or clogged filter.
@@jdawson016 it ended up being the injectors what where faulty , they replaced them all and it's been fine since , bit bad them failing after only 9000 miles
@@sen5908 It seems unlikely that the fuel injectors would be bad at 9,000 miles...However, considering that so many components are made in low cost countries with poor quality control, it could be possible. For your sake, I hope that the repair was covered under warranty.

I've got a tip, remove cut it open and gut it out they serve no purpose and are like cancer to vehicles
Voltage d open circuit 2012 Jetta TDI anyone experience this before.
Also Change fuel filter every 15000km the dpf warning light will disappear
The regeneration happens every 300 miles it happens without you knowing . I had a guy come to clean my filter on my drive as i had gone over the limit . After it was done we went for a drive with his diagnostic computer plugged in to see what was happening . We went on a motor way and it took 30 miles to complete a regeneration. He told ms the % up and down as i was driving at 70mph in 5th it was coming down but if you break it goes up . The key is to always burn fuel never cruise. Its just a shame that the info he could see on his computer was not on the dash board display of the car . The car actually telling you how complete the the regeneration is . This would stop all problems . He also said if the yellow drive to clean light comes on you have left it to late . If you drive correctly it should never come on .
And you should, nt have to go on motorway 1 a week just to clear out DPF, seriously this is the best they come up with, stupid filter 👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎
