I picked up my RS3 on Tuesday and Friday was the first chance I had to install the mods I have purchase. The only things I did this weekend were install TDR springs and the Rostra RF Cruise Control. I installed both before I test-drove the box. I had the battery disconnected for about 15 minutes while I made the connections for the cruise.

Along with the non-functioning tach, I also have the VSC and Trac Off lights illuminated. I have searched this site but could not find anything about the tachometer not working. After reading every post on these lights being on and resetting of the ECU I am at a loss. I attempted to reset the unit by pulling the negative cable off the battery. Left it off for 30 minutes. No other mods have been installed; Check Engine and ABS are NOT illuminated.

Cruise works properly.

Help, anybody!
