2021 Audi Q5 e / A7 e Gearbox Malfunction Warning TSB

Symptoms

Owners of 2021 Audi Q5 e and A7 e models may observe a "gearbox malfunction warning message" displayed in the instrument cluster. This warning indicates a potential issue with the vehicle's electric drive system.

Fault Codes / DTCs

When this warning appears, technicians will typically find Diagnostic Trouble Code (DTC) P0A2B00 stored in the Electric Drive Control Module (J841), also known as address word 0051. This specific code, P0A2B00, indicates a 'Drive Motor "A" Temperature Sensor Circuit Range/Performance' fault and is often accompanied by symptom code 50983. This DTC is the primary indicator of the Audi Q5 e gearbox malfunction P0A2B00 problem.

Diagnosis / Trigger Conditions

This Technical Service Bulletin (TSB) applies if the gearbox malfunction warning is displayed and DTC P0A2B00 is stored in the Electric Drive Control Module. The repair involves checking if the control modules can be updated according to specific Software Version Management (SVM) tables.

Important Warnings

If the software in both the Transmission Control Module (J217) and Electric Drive Control Module (J841) is already at the latest level, or if the installed software versions are not listed in the provided SVM tables, this TSB does not apply. In such cases, technicians should perform the appropriate ODIS test plans for the DTC completely. Additionally, an Audi Technical Assistance Center (TAC) case should be opened with all diagnostic information attached or uploaded.

Repair Procedure Summary

The core remedy for the Audi Q5 e gearbox malfunction P0A2B00 involves updating the software for the Transmission Control Module (TCM), J217, and/or the Electric Drive Control Module, J841. This procedure is guided by Audi Technical Service Bulletin 37 24 11 2063622/3 and requires following the instructions in TSB 2011732 for Software Version Management (SVM) operations. Two SVM action codes might need to be performed based on the specific module updates.

After the SVM update is completed, technicians must clear any remaining fault codes and perform a test drive to ensure the vehicle operates correctly.

Required Software and SVM Codes

To update the Transmission Control Module (J217) and Electric Drive Control Module (J841), specific software part numbers and SVM codes are required. The following tables detail the necessary updates:
