Audi 5000 cluster problems

[Eric Huppert]

Was coming back from Sfest did a 3rd gear pull on the thruway and now my speedometer and my rpm gauge bounces way up in a full boost pull @ any speed. Ran the codes and there was a 2112 code. Cleaned the rpm and tdc sensor off then drove over a half hour ran them again to find there was no codes now. The gauges still bounce. Also the trip computer flashes some times now too.
