I brought my 2013 S6 in for routine service. As usual, I complained about lag and asked for ECU flash, which they wouldn't do without a code. However, they said there was a TCU update to address the issue so they did TSB 2039267/1. Feels better but I've really not driven much.

At the same time they noticed a turbo leak. I had one a year ago and they fixed it with TSB 2036167. They performed the same fix again, new pipes clips, etc. Is this a recurrent S6 problem? I'd hate to have to pay for a blown turbo out of warranty. Anyone else have this recurrent issue?
