    hi all, I have a problem with my speedometer 1.9TDI a3 8l, marks an approximate speed and only when he wants, at first thinkthat it was speedometer, byt now i change it. I've noticed that when you floor the accelerator the speedometer is showing signs of marked and sometimes make, but when I let the high speed needle down.And a change the speed sensor that goes in thetransmission.I put an cruise control bat it only lasts 1 or 2 minutes or in some cases last longer then the car starts to stick pulled and removed cruse control. The vag com does not fault, well it gives an incorrect key programing but I think it has nothing to do with the problem.
    to see if you give me some clue where I can begin.
    Greetings.

    Are you checking the right modules in VAGCOM to test this? try doing a full scan if you haven't already...

    Whats the flashing dash light? somethings not happy...
