Saw two codes flash on secondary device, P2006 & P2007, which means there is a vacuum leak. Supercharger was removed to replace thermostat, mechanic may have left an air leak in the system to cause code and engine check light. Update: Turns out the dealership when they put it back together they crossed the vacuum lines on cylinder banks one and two, thus the check engine light. When they tore into it a second time they discovered their mistake and made the correction.  Coolant temperature climbed as thermostat became stuck closed. Thermostat replaced, check engine light came on as I was leaving the dealership. Replaced by dealer under CPO warranty. Otherwise $1000.

Road debris damage of supercharger radiator. Replaced, and flush and fill radiator. There was a TSB from Audi 4 years ago (TSB 2034439/2) that identified the potential for a rock to enter through the tiny slits (2”) in the base of the A6 grill. They then provided a free plastic inside intercooler radiator cover to try an prevent the damage. I received that TSB. However it was not enough to prevent this from occurring. Arguably it could be considered a design issue. I am annoyed that even after getting the TSB, I still got the issue and had to pay $1600 for the repair.
