Known issues on the 2015 A6. Four recalls are on federal record for this model year. Two concern the electric coolant pump on 2.0L Turbo FSI engines: it can become blocked with cooling-system debris or short-circuit from internal moisture, either of which raises the risk of overheating and fire. A third covers the auxiliary heater electrical connector, which if incorrectly inserted can build up extra resistance and overheat, also a fire risk. The fourth covers the Passenger Occupant Detection System: stress or wear on the front passenger seat's body-sensing mat can cause the PODS control module to malfunction, so the front passenger air bag may not deploy properly in a crash. Owners have filed 22 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing a coolant pump fault to checking the auxiliary heater connector or the passenger seat's occupant sensor, it keeps you on the OEM procedure and the correct specification for your specific 2015 A6.
