2023 Audi A3 Service and Repair Manual

Known issues on the 2023 A3. Two recalls are on federal record for this model year. The first covers the Safety Certification label on the B-pillar, which is missing weight capacity information, meaning owners may unintentionally overload the vehicle and increase the risk of a crash. The second covers the front passenger occupant classification sensor: an electrical connection in the seat can loosen and deactivate the front passenger air bag, so it will not deploy in a crash. The factory diagnostic and repair procedures behind each of those systems are here.

From verifying the B-pillar label to checking the front passenger seat's occupant detection wiring, it keeps you on the OEM procedure and the correct specification for your specific 2023 A3.
