Whats the best way to remove the dpf on an a6 2018 2.0 is it front off or which do you.

This guy knows his stuff !! I would love the opportunity to work along side him and learn all this stuff .as a mechanic theses videos really help with problem cars ..and above all get the customer back on the road without too much fuss ..keep up the good work fella

Great video Gary. Very in-depth, and explained the process very well. Massive thumbs up!!👍🏼

Fantastic to see somebody who knows their stuff! My 68 plate Octavia 1.6 tdi dgte has been throwing up this code and lighting up the EML now for 18 months. When it started lighting up it was just out of warranty as you point out. Strange thing is it has been running and regenerating fine. It's a real pain though, will be my last diesel car, imo they're not fit for purpose anymore.

I feel better now, having sold my 100,000 mile VW 1.2 litre 3 cylinder turbo Polo for spares or repair, it developed the same fault after already, 24,000 miles earlier, having had its EGR valve replaced at some expense. The engine is transverse on the Polo, with all the exhaust plumbing up against the engine bay bulkhead, no wonder the garage who agreed to do the job, said it was a nightmare job! Well done on the video, showing your analytical and logical approach to problem solving.

Thanks for the explanation. Getting this code every 150-200 miles or so. Car had a DFP clean and sensor replacement earlier in the year so wasn't sure why the code kept coming up. Cheers!

Thanks for this video. Currently in the middle of replacing one on a audi b8.5. What a horrible job 🤦‍♂️ this vid really pointed me in the right direction in terms of removal to gain access to the cooler 👌👌

excellent video and description of the problem, thank you for your time invested in making these videos, they are much appreciated!

Excellent work and thought process to correctly diagnose this known fault.

Those heat shields on the bulkhead can be a pain in the ass on some cars,i had a 2005 megane rs225 2.0 petrol turbo,all i had to do was replace an aircon pipe at the rear of the bulkhead. Unfortunately the pipe was 'behind' that heatshield!!It's the fact it's shaped to the bulkhead,i had to try and pull it up and out!Let's just say it wasn't the same shape went it went back in,it took me ages!!it was a nightmare! Another great video!! :-)

This is an interesting case. I’m surprised to see this much carbon after the DPF. Also a delta pressure sensor would have been a better design choice or at least a computer algorithm to only check DPF efficiency when the back pressure valve is in the fully open position. I suspect with the EGR commanded on you would not see a drop in the MAF reading due to the plugged cooler. Great video as always!

Very nice and informative I got the same problem E2000 on my Skoda Octavia.

A very good video with a good explanation of the EGR/DPF layout. One question though, the EGR cooler looks easily to clean as its a tubular heat exchanger but fitting a new one appears to be what everyone does. Is this because its so hard to get to or is there another reason?

Top job excellent diagnosis and explanation

That Code p2002 on Most Diesel cars post 2008 would be caused by a blocked or partially blocked DPF and would be related to a driving profile problem, and in most case it would involve DPF flushing fluid directly into the DPF lowering the engine oil in case of creep and a 60k round trip on the Motorway, so it could do a passive clean. However there are sometimes more esoteric causes for this and other problems that have common causes. That's why its worthwhile getting your car repaired by someone who has experience not just of the problem but how it may relate to your car specifically. Its a good explanation here of a ongoing problem allot of cars with SCR systems are experiencing.

Excellent video. Why are these “consumable” parts buried so deep in the engine? I see similar issues on other VAG/Skoda models. These parts are not cheap, but it’s the amount of labour that’s required that makes it so expensive to resolve. If anyone is replacing these make sure to use genuine / OEM parts, not worth the risk using cheaper alternatives with all the labour that goes into it.

Amazing description, thank you so much for posting the video.

Great video. Is this only blocked because of the adblue system? Or could non adblue systems block up.

I have the same code popping up on my 2017 Skoda Yeti SCR. These newer EA288 engines were supposed to cure the EGR problems by diverting the exhaust through the DPF prior. Trouble is, now with the addition of DEF we are now dealing with a whole new set of headaches. I have an older 2010 EA189 Yeti with 475,000 miles on the clock. Still on original DPF and only ever needed one EGR which was on the front of the engine and took 40 minutes to change.

Great video. Can you maybe tell me whats the real cause that the egr cooler gets clogged like that? I mean sure Ad Blue is one reason.. and how long does it take to get clogged like that again?

Toyatas also have EGR valves for the higher performance deisel engines ( although there will be differences of course ).

Thanks ever so much for the explanation of this system. If the turbo actuator moves from 0-100, can the EGR still be clogged? It's a shame that my 6 year old Audi needs such an expensive repair.

I would of liked to of seen the DPF pressure sensor readings in either live data, scope or other meter measurements. A before and after would of been great. DPF’s block up for fun. We can’t assume that the EGR cooler is always the culprit. Due to the chemical reaction that takes place in a DPF, we have to be carful about our approach to cleaning. The EGR however does not use the same chemistry and can be cleaned many times. I accept though, this job is very labour intensive. It pays to replace with a quality new unit. Thanks for the video…

Hello Gary. Great video and good explanation. I do have a question. The egr difference pressure sensor G450 is placed to monitor the pressure difference over de lp egr. That's it's purpose. Also the ecu knows when it shuts the exhaust flap. At that moment the ecu sees that pressure is rising in g450 and g505 if egr cooler is blocked. Why doesn't it set a faultcode on egr pressure difference to high? That's why g450 is on the car.

Good job Gary 👍

thank you . great video tutorials .one question. Has it ever happened to you on renault 1.6 dci biturbo error p2002 dpf efficiency below the threshold ..

Hi. Gary, the last part of your paperwork on your video states that EGR cooler is caused by a special driving profile. What does that actually mean?

Hi , when or what condition makes the exhaust gas divert thru the cooler rather tham the dpf and straight out the exhaust? Second question , acetic acid, vingear will dissolve urea crystals. Tell me in crazy , cause crazy idea but why couldnt I use a dose of vinegar in place of adblue to clear out from time to time.

Interesting video. Would the style of driving added to this problem? I.E, lots if short stop/start journeys?

How did you loosen the EGR cooler bolts without removing the exhaust pipe? The lower bolt between the exhaust pipe and the cooler. I can't get past it with my tool with an extension...

See a lot of this as a misdiagnosis, given that EGR is monitored via delta pressure it's any wonder this happens. I have seen zero soot conent stored yet P2002 which inevitably leads to an EGR exam and it is totally clogged.

I'm curious what causes the cooler to plug up. Since it's mounted post DPF, all soot should've been captured in the trap. I tought the entire purpose of LP EGR was to have "cleaner" low oxygen air compared to tapping it off straight at the exhaust manifold. Big thanks for sharing your knowledge in these videos.

Very interesting and informative, Do you know if the ASB 3.0 tdi engine has the same system.

Now it is in limp mode with the glow plug light flashing and the 2002 code comes back as soon as it is deleted.

We took all this off the car recently, the EGR valve and cooler were incredibly clean, like new, but the second EGR was pretty dirty and it clogged some holes in the intercooler.

Hello, I am opening the discussion with the following problem: I own a Leon 1.6 tdi, with 198,000 km, engine code CXXA, in which the oil level in the bathroom was increasing, around 1 liter above the maximum level after 5-6000 km traveled. After all the possible tests carried out, it was concluded by a service specialized in the repair of Delphi injection systems that the problem is with the injectors, that they lose at the nuts. I specify that before removing the injectors and checking them, the exhaust pipe was perfectly clean, without soot, as it happens with any Euro 6 diesel, the engine was working perfectly, with no warning lights on the dashboard. After checking, it was decided that one part of the injector must be completely repaired (??), and the others only require nuts and specific adjustments. After 2000 km from the intervention, a little smoke appeared only during short acceleration, and for a short period of time .I wouldn't have noticed the issue if the on-board engine light hadn't come on, accompanied by the error P200200-Diesel Particulate Filter Efficiency Below Threshold B1. In addition to that, the exhaust pipe also smoked. The engine did not limit, it fires as well as before the injector repair. The error can be deleted, but it reappears after 50-60 km. I returned to the service indicating the problem, and this time I was told that the problem is not with the injectors, but with the DPF, which is "broken", that is, it only retains the soot. Somehow I'm in the field, I deal with trucks, I work with the same systems but they're on a different scale, I replied that it can't be a broken DPF. They are euro2 systems that, if they work in optimal parameters, do not produce any soot. I still use injectors, only here he walked. I also attached a picture. I want to know if there is anyone here with the same problem and how they solved it in the end.

The shop that replaced my cjaa's DPF never reconnected the tube running to the lower pressure EGR filter. I'm wondering if this was a mistake or an attempt to prevent this from happening again. But I'm under the impression the EGR system lowers temperatures of combustion and prolongs the life of the engine.

Audi A3 TDI with one of the diesel injectors changed, dpf removed cleaned and refitted. P200200 fault after 100miles of highway driving. Any ideas?

DPF regens happen and Adblue consumption is about 10liters every 6months. I do about 400miles/week on the motorway, it has 93k on the clock. I stuck a boroscope down the intake hoping to get past the EGR valve to confirm a blockage in the EGR cooler, BUT instead the EGR flap motor was struggling to move, It was "dancing" almost like the gears are stripped. Could this be the cause of the p2002 code? Could also be a blocked cooler
