What Does a Blocked DPF Look Like on a Audi A4 TDI?

I was warned, and it finally happened. The dreaded DPF light came on last week on my Audi A4 2.0 TDI and my car entered a "limp home" mode. There's many ways of going about this, sadly none of them are an easy fix. If your car is in a limp mode, it won't be cured from a simple "motorway blast", and it will either need: a MANUAL Regen (If you're lucky), taken out of the car and cleaned through a machine, or replaced.
I went for the middle option, it has been nice and cleaned out, but what does it actually look like on the inside?

The vehicle will automatically fail the MOT test if the filter had been fitted as standard but is found to be no longer present.

Hope you guys enjoy this one, what it takes to remove the DPF from an Audi A4 and what it actually looks like inside. Please note from the UK MOT laws on DPF fitted vehicles: "The vehicle will automatically fail the MOT test if the filter had been fitted as standard but is found to be no longer present." So it is highly recommended you replace the filter or attempt to CLEAN it using the correct practice. Unfortunately we could not capture any footage of this process, so you'll have to take my word on it. Cheers for watching!

[@callumcurtis15]

Just to let you know the mot tester can also fail it if it looks like it has been tampered with and should ask for proof of DPF cleaning documents .

[@stuartrichardson9980]

Great video, I have just bought a 2007 sline 2.0tdi avant in same colour as yours. It was a Jersey car so low miles and no MOT's over there. It has the dpf cleaned out 'fully' but I am struggling to get it through its mot on emissions due to the dpf being cleaned out 'fully'. Did you have any issues or did the remap sort the emissions? Thanks in advance Stu

[@BWTV]

@@stuartrichardson9980 i haven't have any issues with MOTs so I assume the map will balance out the emissions correctly to pass the MOT 👍 ( I'm not a mapper so don't take my word on it!)

@@BWTV you're taking a blocked sieve off of the through flow. Of course it will make a difference. The minute you start driving in town these sh1tboxes start clogging up. Making you use more fuel, which is the REAL reason behind them. If they halved or ⅓'d consumption, guess what, they'd halve or ⅓ your emissions. You can only get out what you put in. Physics. DPF'S & EGR valves simply make you use more fuel, because both seriously f##k up your efficiency.

It's not mad for the fuel sellers & spare part/new car sellers, it's a dream dressed up as good for the environment. All they have to do is implement all the mpg efficiency patent mods that the oil companies bought up & buried to prevent us being ripped off with worse fuel consumption & knackered engines/turbos.

[@BluePixelGaming]

DPF is standard on all diesels since about 2009. If you remove the EGR, you have to remove the DPF. If you remove the DPF, you don't HAVE to remove the EGR. (this is solely in terms of not having the car go into limp mode shortly after)

why you did you not just get the EGR cleaned up and the DPF washed & Flushed through ? would have saved you a lot of time and hassle, VOSA are now checking for DPF gutted cars, good luck.

[@RealGX]

It would only fail again at some point, the DPF wasn't integrated properly on this platform. VOSA aren't checking and there are ways to get around emission tests.

Yes Mr mot tester.. Its got a dpf, I just CLEANED it

[@scooooott]

[@klssn34]

It would have been A LOT easier to leave the suspension alone and unbolt the drive shaft directly at the transmission. It drops down and gives plenty of space for the DPF to come out. Did it that way, worked nicely

Just regen my DPF today from 104% down to 21% but my DPF has a hole in the middle that allows air to go thru.Alfa 159 2.4.The DPF has a flawed execution.Since i drilled it in 2020, never had a limp mode!oh forgot to add, the EGR is stuck in closed position because of the intake manifold swirl flap being left in full open to all air for combustion to happen.Zero black smoke out of my dual exhaust.no need to cut it just drill it at the open ends cheaper faster easier safer.used a cordless drill with a masonry drill welded at the end of a rebar.even exhaust test passed.

Whats the issue for the hard start? i do also have that fault but milder on my b7 2-0 tdi. Startmotor?

[@pgasper1]

I think going forward with performance is good. I like that! I have remapped Audi A8. But it should go along with safety. GET PROPER tyres, not that Chinese sh*t! Then you will taste performance without wheel spin! Cheers 🍻

[@dawa8746]

That's not how it works, bro. EGR cools the combustion temp. to reduce NOx. But it also decreases combustion efficiency, thereby increasing diesel particulate emissions and thus the need for the DPF. Deleting the EGR would reduce DP emissions. DPFs need regular "cleaning" which occurs in the "regen" mode. If you didn't go fast enough for long enough so the regen(s) could complete that'd be the origin of your limp mode. DPF deletion OTOH usually improves MPG as well as performance (HP and torq.)

[@rolensss]

DPF problems are the result of poor engine performance so something is wrong. my man gonna remap engine with bad condition, hell yeaaaaaaaaaaaaaaaaaa🔥🔥🔥🔥🔥🔥

I think you have to remove the DPF & EGR at the same time. Followed up with a sensible ECO-map and you're rocking:)...."Darkside Developments" in "Barnsley" are tuning-masters of performance-diesels....Once the DPF is removed, you get a false-DPF cover round the exhaust to pass M.O.T's. Some garages may simply pass it anyway....

Hi there. Just started watching your stuff. And I have a question. Do you by any change have a guidance on chancing from a old catalyst to a new dpf on a A4 B7 2,0 tdi from 2007. I am searching for it, but I can't find anything on the Internet. So if you had something, it would be nice. Br Steven from DK.

[@ianfrost3529]

Did the dpf go back in🤔. I noticed the slow starting that’s a sign of leaky injector seals or injectors aren’t working correctly a weakness on the 170bhp engine. Would explain the dpf blocking up. But enjoyed the video first one I’ve seen of yours.

[@stewartsaunders5107]

How ironic that Audi, BMW, VW…etc do not have a DPF with a removable end say, with say a gasket so they can be maintained and cleaned out as part of a major service if requested. As an Audi A3 Conv 2010 owner that needs a new DPF…I now know why.

[@MrZimmaframe]

NO....... DPF's are not fitted on "high performance diesels".. By law all diesel cars after 2009 have to be fitted with a DPF's to meet the newer emissions laws, that is the reason some cars do or don't if they are older than from 2009, some manufactures had them on cars before then to meet the new standards before they were enforced. If you're starting a diesel in the cold it might be an idea to let the glow plug light go out first before starting, if not it's like trying to start a diesel engine without glow plugs which is just stupid, and harder on the starter motor and battery.

[@jasonbonde9630]

A car I bought a few years ago (Peugeot 407) had an ABS/ESP light on the dash (so I got it cheap). It took me forever to diagnose it. I went to the main Peugeot dealer and they wanted to fit a new ABS block and pump for about £1,000, so I ran away quickly. I bought my own error reader and found out that the ECU wasn't receiving/calculating a proper torque signal, so I "followed the air" and found out that the EGR had been blanked, and so I assumed it had also been deleted from the ECU. I reflashed the ECU with a stock file from the internet and suddenly I was getting a bunch of errors telling me that my EGR valve was stuck! Cleaned it out and the error light went away..
