Hoping to get some advice from those more knowledgable on audi's than myself. I picked up a 1993 90 quattro for a winter car and I need some help with an electrical issue.

The whole issue is with the instrumnet cluster. The gas gauge and the coolant temperature gauge do not work. Also the odometer worked when I drove it home but now it does not. And there is no back light in the instrument cluster.

Okay so some background. I read about the instrument cluster issues a little and what I could find said that if both the temp gauge and the gas gauge are not working that the voltage regulator is the most likely culprit, I also read that like my other old german car the plastic odometer gears can break causing it to work intermittently or fail completely. So I replaced the voltage regulator and blew the cluster apart only to find that the odometer gears are fine and the voltage regualtor did not fix anything. So what else could cause these problems? How can I fix it?

I am hoping this a relatively common problem and someone on here can help me out.

Thanks
Matt

resolder all of your instrument cluster... its sucks but thats the other coman problem with them.

Tried that, also re-wired the broken wires in the trunk hinge this weekend. Niether of which worked.

I am stumped, as is the rest of the audi community it seems. Hopefully I just have a bum cluster.

i know this is gona sound extremely stupid... but... did u check ALL of your fuses?

matt_e30

Yes I checked ALL of my fuses. I also checked the dimmer **** to make sure that wasn't the reason the dash lights were not working.
