1990 Audi 200 Odometer not working
I purchased a 1990 Audi 200 (not quattro) that has been sitting for the
past 4 years. I got it running and everything seems to be in good working order with the exception of the odometer. What problems would cause this and how can I remedy the situation? Any suggestions would be extremely helpful. Thanks! |

1990 Audi 200 Odometer not working
There is a small gear in the back of the odometer that breaks when the trip
odometer is reset while the car is moving and usually when the last two digits are '99' on the main odometer. Some owners who post of Audiworld have reported varying success in pulling the instrument cluster and disassembling to get to the part. They then use glue to fix it. Others find a working IC in a used parts (junkyard) place for $20 to $40 and replace the whole thing. Others just live with the inconvenience because finding a working IC is rare because almost all T44s have encountered this failure.

1990 Audi 200 Odometer not working
Hi,
Seems to be a very common problem. There is a little gear wheel in their, which is placed between a small stepper motor and the odo wheels themselves. It feels quite rubbery, don't know whether that's the age or whether it's like this from the beginning. If the speedometer is working but the odometer not, that's a very likely candidate. I replaced it with one from the scrap yard, only to get the same failure a year later. It's a bit of a pain to take it out, so I would recommend getting a new one. It looses one or two of its teeth, I don't know how one would be able to fix that with glue (and it would very likely loose more teeth later anyway). I don't agree with the statement that it happens when the trip odometer is reset. First of all it dis-engages the mechanism, so it shouldn't be a problem. Nevertheless, I am sure I didn't reset the trip odometer while driving and the second failure was witth the trip odometer at ~360km (can't remember where it was on the first failure). Scott Brotherton from Continental Imports ( http://www.continentalimports.com ) used to sell the gear for US$ 20 plus shipping. If anyone knows a European source, I would appreciate it (shipping from the US is just very expensive). If you decide to take it apart, you will need to get the needle off. The best way is to twist it carefully counterclockwise, then it will come off (don't try the pulling straight off some recommend). I got this trick from Rick Borth from Overseas Speedometer ( www.speedometer.com ). If you decide not to repair it yourself, it might be worth to get a quote from him. There is a web page somewhere with the wiring diagram of the speedometer. It's actually quite simple. If you can't find the web page, I might still have a copy of it on my pc. At some stage, I made some sound files with square waves, corresponding to different speeds (20, 40, 60, ... km/h), hooked the speedometer up to the pc sound output and played the sound files. That way I was able to test the speedometer and odometer and to callibrate it at the same time. I might still have them somewhere, let me know if you need them.
