Symptoms
Owners of 2021-2022 Audi Q5 and A6 vehicles may not directly experience symptoms related to this issue. Instead, the problem typically manifests as an event memory entry logged in the gearbox control unit. This can occur after replacing parts or performing other gearbox-related work.
When technicians attempt to activate the gearbox control unit, event memory entries related to the calibration of the auxiliary hydraulic pump are logged. The system's adaptation routine, which should start automatically, fails to do so or is interrupted.
Fault Codes / DTCs
This Technical Service Bulletin (TSB) 2074823/1 specifically addresses a single diagnostic trouble code (DTC):
| Code | Description |
|---|---|
| P17EF00 | Hydraulic pump cannot be adapted |
This code indicates a failure in the adaptation process for the auxiliary hydraulic pump within the gearbox control unit.
Diagnosis
The issue is identified when activating the gearbox control unit, which should automatically initiate the adaptation routine for the auxiliary hydraulic pump. However, this routine is interrupted, preventing proper calibration. The presence of the Audi P17EF00 hydraulic pump fault code in the event memory confirms this condition.
Repair Procedure Summary
To resolve the Audi P17EF00 hydraulic pump issue, the Transmission Electronics (J217) control unit requires a software update. This update must be performed using the specified Software Version Management (SVM) code via the ODIS diagnostic system.
The process involves updating the gearbox control unit with the latest software version. For 2021 Audi Q5 models, the update moves the software from part number 80A927155DQ (version 0002) to 80A927155DQ (version 0003) using SVM code 02A223. For 2022 Audi A6 models, the new software part number is 4K0927156BD. Technicians should refer to TSB 2011732 for detailed instructions on SVM operating procedures.
Important Warnings
Technicians are advised to always use DoIP (Diagnosis over Internet Protocol) when flashing a control module via ODIS in supported vehicles. This ensures proper communication and successful software updates. DoIP can be activated in ODIS via Administration >> General >> GFF Process >> DoIP communication >> Only allow DoIP communication.
