Dpf & Egr Removal

[Confused]

Hi everyone 

I'm looking to get both the dpf & egr removed or deleted which ever is better,( I've got error code P2002 plus been advised by Audi specialists my egr cooler has gone & the dpf, well who needs to replace one of those) but looking for somewhere reliable to do the work, any suggestions? I can get it done  round the corner from me but just have a feeling about the company that I just dont trust them. Oh any ideas on how much it will be. 

Thanks for any and all responses

Hello Simon,

Sorry to hear of your issue, particularly since the replacement costs are likely to render that route as being uneconomical. 
I terms of deleting, I would first be taking experienced advice on this, and the potential MOT implications, before spending anything on that route. 
Let’s hope someone who has experienced views of been-there-done-that will be along to help, or if there is indeed experienced advice to just not go there. 
Kind regards,

Gareth.

Hi if you get the DPF/EGR removed or deleted you will be forever getting dash warnings, no one has yet come up with a software that can delete the low pressure cooler which is I suspect the reason you are considering this route, please observe the following, if you remove the main EGR you raise both cylinder head temperatures as well as the turbo temperatures as the gas will be a lot hotter, this will also raise Nox1 emissions which the sensors in the exhaust stream will pick up hence the lights on the dash, I am pretty sure the code you have is p2002 particle filter bank one above threshold, the DPF is not itself blocked just the cooler, I have had a couple of these apart, also try and disseminate between the cooler and the main EGR which rarely gives trouble also might be worth looking at on site cleaning /mobile where they come to you and run cleaning solution through the exhaust system via the sensor hole on the cat.

Thanls for the reply Stevey oh this is the forst ive heard this, only read what an improvement it makes to the cars performance and obviously no parts to go wrong. Guess I'll give some more thought.

Simon,

EGR & DPF Deletes have all sorts of pro's and cons.
to be honest, in all the research i have done, i cant come to a consensus on it at the moment myself.

Ive been thinking of doing the same thing on my A8 3l tdi.  Stage 2 Tune about 340bhp with a tuner i know! 
Hes not exactly sure what torque figure but its fairly impressive.
If cat is still in, you might pass the emmisions tests but not definite! 
If the EGR isnt there any more and the engine is no longer breathing its own gasses, then surely theres going to be alot less carbon buildup in the engine.
Maybe a bit dirtier smoke wise tho.
Only way to decide for yourself is to talk to the people that do it and not just a "Why should i do it", but more of a "If i do this, whats the effect?  Whats the alternatives" kinda conversation.  Im still on the fence but seriously starting to sway towards a decision!

Heres a couple of sites i have been reading thru for info

I could go on giving links all day, but its fairly pointless cause anyone can google as well as i can.

Have a chat with the tuner that your considering, have a read about it and decide for yourself.

My 2016 a4 2.0 tdi is mapped up dpf removed and adblue removed and has no lights on the dash

I’ve just taken all of the silencers out too and I’ve never had a problem. The valve was still left in the exhaust tho to stop any lights and it’s a fly machine it’s gone from 150bhp to 198bhp it’s better on fuel and just drives better. I’d definitely advise mapping your car and getting rid of silencers for more exhaust gas flow and obviously map the ad blue out and gut dpf there’s only a puff of smoke on start up wen cold that’s it. Not even on full throttle.
