Known issues on the 2020 RS3. One recall is on federal record for this model year, covering the passenger occupant classification sensor: the passenger occupant detection system can malfunction and switch off the front passenger air bag even when the seat is occupied, increasing the risk of injury in a crash. The factory diagnostic and repair procedure behind that system is here.

Whether you're verifying the occupant classification sensor or working through a routine service interval, it keeps you on the OEM procedure for your specific 2020 RS3.
