Known issues on the 2013 A6. Six recalls are on federal record for this model year. Two cover the Passenger Occupant Detection System sensing mat in seats with heating/cooling, which can malfunction and prevent the front passenger air bag from deploying as intended in a crash. Two cover the electric coolant pump on 2.0L Turbo FSI engines, which can be blocked by cooling-system debris or short out from moisture, overheating and raising the risk of a fire. Two cover fuel system hoses and lines that can weaken or degrade, leading to a fuel leak that raises the risk of fire near an ignition source. Owners have filed 52 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're tracing a coolant pump fault, checking the passenger seat occupancy sensor, or inspecting a fuel line, it keeps you on the OEM procedure and correct specification for your specific 2013 A6.
