Known issues on the 2012 A6 Quattro. Eight recalls are on federal record for this model year. Three involve fuel delivery: a weakening fuel line compression point, a degrading engine-bay fuel hose, and a fuel injection system leak, each raising fire risk in the presence of an ignition source. Two cover the coolant pump on 2.0L Turbo FSI-equipped variants, which can become blocked with cooling-system debris or short-circuit from moisture and overheat, also a fire risk. Two address the Passenger Occupant Detection System, where seat sensor mat wear or malfunction can prevent the front passenger air bag from deploying properly in a crash. The eighth covers a stitching defect in the curtain air bag seam that can keep it from deploying to protect an occupant. Owners have filed 59 complaints for the year.

Repair and diagnostic procedures follow OEM specification for the 2012 A6 Quattro.
