    White smoke

    Hi.
    I own a 2008 A3 2.0 TDI 170, which has been remapped and DPF deleted.

    Usually when I put my foot down and go high thru the rev range I get a puff of black smoke (obviously as the DPF has gone), but this morning I noticed every time I went high thru the rev range I was getting quite a lot of white smoke.
    This doesn't happen during general driving or on tickover, just when I'm giving it the 'beans'.
    Anyone know what this could be?

    Chris

    It's unburned fuel in your exhaust system. Probably due to your injectors failing due to the increased demand imposed on them.

    Ah right. Is there anything I need to upgrade or should it be ok?
    I'm not heavy footed all the time, just blow the cobwebs off every now and again. :-)

    Just to jump in on this one... Why do the cars smoke so much black smoke? My 140 let's out small clouds of black smoke every time I floor it and I can't help but think its just a little too much.
