fault lights
 

Hi all. I'm new to the RS6 world and just purchased my blue with silver a couple of weeks ago. When it arrived I did OCT ECU and TCU upgrades. After about 100 miles the traction control light and ABS light came on solid. Power decreased as well. Brought it to the performance shop and teh tech that set it up said it had a brake switch fault code and traction fault code - shocker as this was what was lit on the dash. I have warranty but perf tech is telling me that he wants to swithc out tcu before I go to Audi. Does any of this sound familiar? Could teh problem be from teh upgrades?

Might be a bad speed sensor? I'm guessing VAG-COM would be more specific?

What is VAG-COM?

YES, you could have the dreaded transmission or Torque Converter problem
 

If the dealer sees a aftermarket chip. You are toast.

Link to some info...can also use the friendly search...good luck

I did notice the transmission started to slam a little bit. Thought that might be linked to the fault lights somehow.

Some have reported a faulty brake switch as causing this to happen.
