| Apr 2017112000 miUS $476 | Replaced all four TPMS sensors after the tire pressure and TPMS warning lights were illuminated. My VAG-COMM tool showed that the batteries had failed or was extremely low in my TPMS sensors. Actually, thinking about it, I probably should have replaced the TPMS sensor in the spare tire as well. NOTE: Repair was originally done by Discount Tire with HUF universal TPMS sensors. This did not correct the problem. The TPMS warning light continued to be displayed after the installation of the new sensors. Subsequently, replaced the universal TPMS sensors with Audi brand sensors. This corrected the problem. The "universal TPMS sensors" do not seem to be compatible with the Audi A6. | ||

| Oct 2017115500 miUS $350 | After having the 115K service performed by an independent Audi mechanic, the ESP, EPC, and CEL (blinking) lights became illuminated on the drive back home. I returned to the independent Audi repair shop. The owner of the Audi shop (an Audi expert) checked the car out. He did not find any reason for the ESP, EPC, and CEL fault. However, he suggested that the ignition coils be replaced. The ignition coils were replaced at cost with no labor charge as a courtesy for the inconvenience of having to return to the shop After having the ignition coils replaced by the independent Audi mechanic, the EPC, EPS, and CEL (blinking) lights came back on the way back home. The vehicle was then taken to the Audi deal for analysis of the codes. The dealer kept the vehicle for several days, but could not any reason for the codes. I was charged $300. This was essentially, a $100 charge to troubleshoot each code separately. Although I explained that the warning lights all came on at the same time, the service adviser indicated that they needed to troubleshoot each code separately. Later, the service adviser claimed that the time that the mechanic spent trying to diagnose the problem was easily double the amount that I paid. The car was returned to me without the mechanic at the dealer finding any problem. The codes were reset by the mechanic and did not occur again while the car was at the dealership. | ||
| Nov 2017115474 miUS $2540 | EPC, ESP, and CEL (blinking) lights became illuminated again. Car was towed to the independent Audi repair shop.
