Known issues on the 2018 A4 Quattro. One recall is on federal record for this model year, covering the seats: the cable linking the seat heater to the Passenger Occupant Detection System can develop a contact fault, causing the system to misdiagnose a malfunction and disable the passenger air bag, raising injury risk in a crash.
