    So I have recently had the DPF and EGR mapped out of my 2.0tdi cr A6 avant (170).
    Min first drive I only noticed a slightly better sound coming from the turbo so guessing that knocking out some of the DPF inners has unrestricted tat part of the exhaust.

    power wise I did not notice any initial gains.

    saying that I then took it into the motor way and higher up the Rev range I think there is a slight difference.

    it was not mapped for performance but I do now get slightly better mpg.

    just thought I’d share my experience with this!!

    Here’s a photo to make some if you’s smile 😂

    May I ask who mapped them out and how much it set you back?

    Cheers

    Was a local Indy garage who carried out the work, then called in some one who deals with the mapping side of the engine. Set me back £350 for all work. I have been running the car only on shells diesel (v power stuff).
    i must say that now after having the car back 2 weeks it does feel more responsive, spools up a little quicker and looses traction in 2nd gear when foot planted. (Didn’t really do this previous to the work unless roads were wet)
    but I did use supermarkets diesel prior to this for about a year, hence the clogging of the dpf.

    cheers

    How are you going to get a legal MOT?
    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.
