    :sos:Hi guys, wonder if any of you can help me with my problem, I've got the 2007 2.0 TDi 140 BKD engine A3.
    Yesterday I was driving along & stopped at a junction, I heard a beep & my ABS & ESP light iluminated on my dash with a message saying fault, see car manual.
    Then I parked up & went into my doctors. Got back in the car & the lights had gone out! Started off fine, but then my car wouldn't shift past 3rd gear unless I redlined it:wtf:I thought! Today I got in the car lights came back on dash, yet gears were smooth again. This is intermittent, when the ABS & ESP lights are on, gears shift fine, when the lights go out again my car drives as if it's in sport, I'm having to rag it to get it to auto change. Paddles work fine tho, as does the shifter in m mode:wtf: My car is confused! :blownose:

    Any Ideas guys?? Pleeeease!
    cheers in advance!

    I wouldn't be an expert but it could be the mechatronics unit which is known to give problems.

    When it's warmed up does jerk when taking off in first gear or reversing?

    Also does it shift down to early to second gear when slowing down?

    Hi, I'm not having jerking probs, just that my car thinks its in sport when in D & It revs its t**s off before changing up. I Can change up & down smoothly with stick & paddles, just not in D auto.

    Hi there, for me is was a rear speed sensor, it can also be the wheel bearing causing the sensor to react & give false readings. My gears were erratic as hell, as soon as I had the speed sensor done it was sweet.
    The sensors are cheap, but the labour the stealers will charge will take it up over £200.00+. If you know a mechanic who can do it on the cheap, avoid huge un-necessary labour charges.
    Hope you sort it.:blackrs4:
