Known issues on the 2019 A3. Three recalls are on federal record for this model year. The first covers the passenger occupant detection system: it can malfunction and switch off the front passenger air bag even with the seat occupied, increasing the risk of injury during a crash. The second covers the tire pressure monitoring system: an undetected sudden loss of pressure in all four tires increases the risk of a crash. The third covers the fuel system: a suction jet pump seal inside the tank can fail, letting fuel flow into the evaporative emissions system and leak out of the charcoal canister, and a fuel leak in the presence of an ignition source increases the risk of a fire. Owners have filed 12 complaints for the year.

Whether you're inspecting the passenger air bag sensor, checking the TPMS wiring, or tracing a fuel system leak, it keeps you on the OEM procedure and the correct specification for your specific 2019 A3.
