I had similar problems with speedos in two 1990 Audi 100s, it was some time ago, but the contacts on the circuit boards on the back of the speedo deteriorate and do not give a good contact. I bought second hand speedos, only to find they had similar problems, eventually it was very easy to fix, I shaved matchsticks to chisel points and pushed them into the circuit boards to add pressure on the contacts and improve connection. After that repair drove the cars for a few years and the problem did not recur. It was a long time ago and I cannot remember exactly where the matchsticks were placed but look for soldered points near the edges of the boards. Regards, Michael

There is 2 locations for that car.
#1 under hood passenger side, front side of shock tower,with fuel line connected to it.
#2 under car driver side, below seating area,front of fuel tank mounted on chassis. If you have the 90 Qauttro,it's under hood,pass. side, front side of strut tower, mounted on fender well.

turn the top counter clockwise u might need to use screwdriver and hammer as it is tight just to get first few turns then u can do it by hand. the rest u should be able to figure out. make sure fuel lines r disconected at pump
The best solution is to use a Vehicle Specific Wiring Kit, as these cars have complex electronics that do not like being overloaded, Also the car has towing specific safety systems (such at Trailer Stability Program) which only work if it knows it is towing. The car will need to be coded to recognise the towbar wiring and work the saftey systems properly after the kit has been installed. It's not cheap however, Expect to pay around £200-£250 for the whole job.
