Known issues on the 2020 A3 Quattro. Three recalls are on federal record for this model year. The first covers the front passenger air bag occupant classification sensor, which can malfunction and deactivate the passenger air bag even when the seat is occupied, increasing injury risk in a crash. The second covers the tire pressure monitoring system, which may fail to detect a simultaneous loss of pressure in all four tires quickly enough. The third covers the fuel system: a worn suction jet pump seal inside the tank can let fuel migrate into the evaporative emissions system and leak out of the charcoal canister, raising fire risk in the presence of an ignition source. Owners have filed 16 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From a PODS fault to a fuel tank seal inspection or a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2020 A3 Quattro.
