Airbag light came on (Belt Force Sensor for Seat Occupied Recognition - code 02513). Indy Audi mechanic replaced seat belt at a cost of $445 for the belt and $105 for labor. Unfortunately, this did not fix the problem. Light came on again. 
112000 mi

US $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.

59670 mi
