Picked up the car from the body shop on Friday. Within 5 minutes of driving it, the check engine and EPC lights come one. Took it back to Audi and they said something about intake sensor. It just never ends...

I had a bad intake sensor and bad vacuum lines. Finally got my car back after 6.5 months! Seems to be OK except for a harmonic vibration at about 2-3 K. Does it more while cold. Good luck getting parts!

I just don't buy the whole "RS4 is an exotic car" argument. There needs to be a better inventory of parts in North America, and better availability of RS specialists in the service departments.
