Service Bulletins

Audi released several important technical service bulletins in May 2026, primarily addressing electrical, battery, and powertrain concerns for the Audi Q5 e. These bulletins provide guidance to technicians on diagnosing and resolving issues that owners might encounter.

One significant concern is an electrical system malfunction that can prevent the vehicle from going into drive. TSB 2081028/2, affecting 2021-2025 Audi Q5 e models, and its earlier version TSB 2081028/1, for 2021-2022 models, address this issue. Common diagnostic trouble codes (DTCs) associated with this condition include P0AF800 and U01A000, and technicians are advised to report these to Audi's Technical Assistance Center.

Another recurring issue involves 12V battery discharge in 2024-2025 Audi Q5 e vehicles. Technical Service Bulletin 2074126/5 (superseding TSB 2074126/4) details how high-voltage charging unit bus wake-ups can lead to a drained 12V battery, especially after the vehicle has been stationary. Audi has provided a temporary workaround while a permanent solution is developed.

Owners of 2021-2025 Audi Q5 e and A7 e models might also experience a "Gearbox malfunction message" accompanied by DTC P288200. Technical Service Bulletin 2070965/5 outlines a software update for the transmission control module to resolve excessive engine disconnect clutch slippage, which is the root cause of this warning.

Finally, a bulletin addresses high-voltage battery deterioration in 2021-2024 Audi Q5 e PHEV models. TSB 2079556/1 indicates that the Malfunction Indicator Lamp (MIL) may illuminate due to deterioration in various high-voltage battery modules. This can trigger several DTCs, including P0A7F00, P0EDD00, P0EDE00, P0EDF00, P0EE000, P0EE100, P2CCC00, and P2CCD00.
