#43 of 70 instrument cluster problems by digitoo

Oct 14, 2008 (7:50 am)

For those of you that have had problems with your instrument cluster going bad and giving you false readings such as the gas gauge not reading correctly, false codes, etc, you are not alone. I had problems too with my gas gauge not reading properly after I bought a used 2001 Audi TT quatro roadster. I bought it in 2004 with 57,000 miles and less than a year later the gas gauge started acting irradically. I took it in to my mechanic who works on European import cars and he tested the fuel tank sender, etc (also my ABS and another warning light would come on and off sporadically). He suspected the cluster and said I had to go to the dealer (2-1/2 hrs away) to have it repaired and it would cost at least 1,000 or more to fix. That was more than I wanted to spend so I just used my trip meter to gauge my fuel and never went more than 300 miles without filling up. Then earlier this year I got a notice from Audi saying that there was a lawsuit against them and in order to settle the suit, Audi would replace the instrument cluster if your car had a certain vehicle ID# ending in XXXXX and your car was under 5 years from when it was put into service and you could prove that your cluster was bad. They would reimburse those who paid to have the cluster replaced and for those who had proof that the cluster was bad within those perameters, they would allow you to go to an Audi dealer and have your cluster replaced. I sent them proof of my cluster being suspected of being faulty and a few months later Audi sent me a letter to have my car fixed within 45 days. I took my car into the Audi dealership, thinking they were the experts and knew how to fix it, but I've had nothing but problems (more than before) since they put in the new cluster. My mechanic feels they did not clear the fault codes before putting in and programming the new cluster because my ABS and other warning light still come on and off at will. My fuel gauge even gave me a false reading on day. I was at a 1/2 tank and when I drove to the store and got back in my car it read between 1/2 and 3/4, then I drove to the next store and when I got back in it read 3/4. So far that has been the only time it did that, but the temp gauge reads anywhere from 1/2 (normal) to the line just to the left of it (2nd line) or sometimes just a little bit under the 2nd line. Audi has bad customer service when it comes to complaining about their work and want to pin it on anything but the new cluster. Anyway, the whole point is that Audi is replacing the faulty clusters (they did admit to using faulty clusters in their cars 2000 -2005) so I would suggest you google Audi instrument cluster lawsuit to see if you can get reimbursed or have your car fixed.

#44 of 70 Seat heater by digitoo

Oct 14, 2008 (7:58 am)

Did anyone have problems with their seat heater coming on mysteriously? I haven't used my seat heater all summer. A few weeks ago I was going to a seminar and thought my seat was rather "warm" feeling. I thought nothing of it and parked my car. Driving home I noticed that my seat was REALLY hot, as if it was set on the highest setting. I fiddled with the control knob thinking it might turn off on one of the settings but it didn't. I got home and felt the seat, it was really hot so it was not my imagination. When I went to get into my car the next morning it was DEAD!! I thought my seat heater "fried" the electrical system. I called AAA and he looked at it and he could smell an "electrical" smell in my car. He decided to jump start my battery (it was only 3 mo old) and it started. I drove it to my mechanic and he said that it was drawing power (the seat heater was not shutting off when the car was turned off). They took the fuse out to prevent it from doing it again. Has anyone had a similar problem and if so, what was the cause? I think it was related to my faulty cluster but my mechanic is not 100% sure about that, but thinks it might be a remote possibility. When I called the Audi dealer he said it was a faulty switch, but I never touched the button since last winter. Anyone else have the same problem??

#45 of 70 "Service in 1000 Miles" by zeusbully

Oct 29, 2008 (12:08 pm)

I have a 2001 TT that has had it's instrument cluster replaced 3 years ago, and has no signs of odd electrical problems. But I have had a message pop up ever time I start the car lately. The car has 102xxx miles and I feel this countdown "Service" message is mileage driven notification. It progressively says service in 1000, then 900, then 800miles, etc.. Until the 300mile mark. Now it says "Service!" upon starting only. I find no obvious issues, and I do work on the car myself when possible using the Bentley manual.
I know there is a trick to push in both silvere posts on the gauges to erase service codes, but it only seems to do a self-test when I attempt this. Then still displays the predictable the next time I start it.
Does anyone know if this is a serious issue? Should I just visually check the timing belt (also replaced 3 years ago) and erase the code?
Any ideas??
Much appreciated!

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 )
Water pump (exploded into 3 pieces)
Switch for radiator fan
Brake light sensor
Plus couple other things that I cannot remember
 
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?

#50 of 70 Brake warning light by whitr

Feb 23, 2009 (9:12 am)

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
