Audi TT Electrical System Problems



  • window will not retract or exstend when door is opened or closed any ideas what problem is? 2001 audi tt
  • Did your ever find out why your ABS warning and ! light up on dash as for the past 2 weeks after i have been drivin for a bit the same thing is coming up on my TT
  • Iit will be a year in a couple weeks since I purchased my 2001 Audi TT coupe and for that last 5 months I've been at the shop.

    Head gasket
    Timing Belt
    Radiator (then back again for the plug because I hit a bucket on the free and it emptied out the radiator fluid.ugh.... at 2:30 am :cry: )
    Water pump (exploded into 3 pieces) :mad:
    Switch for radiator fan
    Brake light sensor
    Plus couple other things that I cannot remember :sick:

    Today I was driving home and my battery light came one, along with the ABS and the Emergency brake light was flashing. Oh and some other light with a curvey thing and arrow on the dial for RPMs.

    For the past 2 months the fuel gauge frankly has not felt like working correctly so I've kept the mileage under 300 after filling up.

    One morning last month my gas, trunk and interior alarm buttons would not work. I have a manual but of course it was not in the car. Lucky that I had enough gas to make it to work. I called my mechanic and he told me how to manually open it and it's been working since (crossed fingers and silently praying it will continue).

    There was a mention to a letter from Audi about repairing something and now I know that I must find it the letter or google it.

    So any help on why the brake light flashes, abs and battery light in the center gage and the curvy arrow are on would be awesome.

    Best of luck to all

    Why does something so pretty not work correctly?

    I too have my brake light flashing, not all the time, but enough. I spoke with the dealership and they told me to not worry about it unless it stayed on solid (not blinking). Oh well. Mine is an '02 TT w/100k miles. Does anyone know what this is; at the bottom of my cluster in the center I have a message that stays on, 99:59h

    Seems I am having the same problem with our 2000 TT Quatro, did they find out what the problem was with yours? I cannot seem to keep the battery charged!!!! Any info appreciated, thanks
  • Ah, I had a drain in the stereo system of my 2000 TT. Audi was not helpful at all in fixing it - they replace the instrument panel but the problem persisted.
    I am thinking it was a short in wiring. Tested head unit, tested amplifier, tested CD unit, tested speakers - no dice. Tested amperage at the fuse box - it spiked intermittently high enough to cause a drain of the battery every 10 days or so. Since I knew it was in the stereo line, but just could not find it, I unplugged the fuse to the stereo when I was not using the car. Drove it that way for 2 years, no problem.

    I have electrical cluster problem on 2000TT. I had alternator and battery fixed 10 mos ago by foreign motor garage but they now say I have to do to dealer.
    I can travel if someone has had this fixed in the general area.

    I bought my almost new TT a month ago as the 2nd owner with just 27Kkm.
    Few days later started to notice that the suspension malfunction light is on and at that point the drive mode select button (sports or comfort mode) stops responding. Local dealer spent almost 4 days trying to fix the problem but with no proper results yet and i am starting to worry now. Any idea guys....?
  • Bertola,

    The exact same thing has happened to my 2001 Audi TT. I have more mileage but it seems to be exactly the same issue...I was driving down the highway and the car started starving for fuel and shut off. It will turn on for about 5-10 seconds and then shut itself off again. I have checked ALL RELAYS, the fuel pump, all wiring that I could think of. I cannot find the problem. Did you ever find out what was wrong with yours?

    I have had the same problem. My key remote was not working. So i had it sincronized with the car and now all is working again.

    sounds like the same problem i am having now, im wondering if you could save me some time, did you ever get this resolved?
  • That was a nightmare that lasted months. No one could find out for sure what the problem was. They replaced every computer in the car to no avail. My car ended up totaled because of that. Good luck
