So I took the RS4 into the dealer today to diagnose what was causing a CEL. It came on for about 2 hours at the beginning of last week and then shut off. "Luckily" it came on again this weekend when I had an appointment scheduled for Monday morning.

I just got the car back today and the invoice lists the following:

SCAN TOOL DIAG. FOUND FAULTS FOR CYLINDERS 2,3,5,7 MISFIRES. CONTACTED TECHNICAL ASSISTANCE..TECH ASSISTANCE USED telediagnosis and updated both ECMs to SW 0030. FAULT MEMORIES WERE CLEARED. CHECKED SOFTWARE LEVELS TO VERIFY SOFTWARE UPDATE WAS PERFORMED. TECHNICAL ASSISTANCE ALSO ADVISED TO PERFORM TSB 2022030/1 ADDING FUEL ADDITIVE. TEST DROVE VEHICLE FOR 60 MILES AS ADVISED IN TSB. UPON RETURN CHECKED FAULT MEMORY. NO FAULTS CURRENTLY STORED IN EITHER ECM...VEHICLE WILL NEED TO BE CHECKED AGAIN ON NEXT COLD START.

I've done a search here, AudiZine, and Quattroworld and couldn't find anything on any of the sites. If anybody here knows what this means, please tell me. Thanks in advance.

Just had this same thing happen today. CEL came on...but engine runs fine. Dealer recommended TSB 2022030/2.

Carbon build up on intake valves, you will eventually have to get intake pulled and clean intake valves
