2013 Audi A6 Quattro - Diesel Filter Removal - Jaktar1

Dear John, I have been told that by removing the above component greatly improves the

the performance and helps fuel consumption. This cost's in the region of £250 by a specialist. Is this in fact true ?

Kind regards.......Jaktar1.

Remove the DPF on a 2013 and you will loose the warranty on the car (possibly only the engine and transmission) since its a modification.

I have calculated using the fuel log for one of our DPF equipped cars that in 10,000 miles regens use possibly 3 gallons of extra diesel, the remainder of the time it works like a car without a DPF. That is less than £20 a year and even if you could get the DPF removed, bypass pipe fitted and the software changed to suit the DPF deletion for £250 (which I doubt) it would take you 12 years to recoup the outlay.

But why on earth do you want to do this. Its a new car, if a diesel with DPF is unsuitable for your use you should have bought a petrol.

Whilst not stricly illegal in the future it is highly probable that a check of some sort on the DPF will become part of the MOT, you will then have to re-fit one to get back on the road.

We have 2 cars with DPF's the oldest of which is 5 years, never had a problem and only do 8000 miles a year in that car.

I hope this post is a wind up.

Well, even if it is, you've given a very comprehensive and useful answer which anyone thinking about DPF removal should read.

I think that newer cars - and certainly the VAG common-rail diesels - have improved DPFs which regenerate when necessary and are much less inclined to clog up and require a visit to a dealer.
