2021-2024 Audi Gearbox P17EF00 Hydraulic Pump Adaptation

What is the Audi P17EF00 Gearbox Fault?

Audi Technical Service Bulletin (TSB) 2074823/2 addresses a specific condition where the auxiliary hydraulic pump within the DL-382 Gearbox control unit cannot be adapted. This issue is identified by the diagnostic trouble code (DTC) P17EF00, which is stored in the gearbox control unit's event memory.

The TSB notes that there is typically no direct customer complaint associated with this fault. Instead, the P17EF00 code is often logged in the event memory after service work has been performed on the gearbox, such as component replacements or other repairs. The core problem is that when the gearbox control unit is activated, the automatic adaptation routine for the auxiliary hydraulic pump may be interrupted or fail to start, preventing proper calibration.

Diagnosing the P17EF00 Code

Workshop findings indicate that event memory entries related to the calibration of the auxiliary hydraulic pump are logged when the gearbox control unit is initially started. During this process, the adaptation routine, which is crucial for the pump's correct operation, does not begin automatically. This leads to the storage of the Audi P17EF00 gearbox fault code.

Important Warnings and Warranty Information

Audi emphasizes several critical points for both technicians and owners regarding this TSB:

• "Otherwise, this solution will not eliminate the problem and repeat repairs may be necessary. In such a case we may reject the warranty claim and charge back the cost of the removed parts."
• For vehicles equipped with high-voltage components, the high-voltage cable must be removed before entering the SVM code for the software update. This is crucial "To prevent charging of the high-voltage battery during the software update." Ignoring this step could lead to damage: "Charging the high-voltage battery during a software update can damage the high-voltage components."
• "All warranty claims submitted for payment must be in accordance with the Audi Warranty Policies and Procedures Manual. Claims are subject to review or audit by Audi Warranty."

If your vehicle is outside of its warranty period, this Technical Service Bulletin is for informational purposes only, meaning the repair costs may not be covered.

The Official Repair for P17EF00

The official repair procedure for the Audi P17EF00 gearbox fault involves a software update to the Transmission Electronics (J217) control unit. This update must be performed using the specified SVM action code 02A223.

After the software update, the adaptation routine for the auxiliary hydraulic pump will start automatically, and manual adaptation is no longer required. Technicians are instructed to follow the specific instructions provided on the vehicle diagnostic tester during this process. For detailed guidance on Software Version Management (SVM) operations, TSB 2011732: 00 Software Version Management (SVM), operating instructions, should be consulted.

What Owners Should Do

If you own a 2021-2024 Audi A4, A5, A6, A7, or Q5 model equipped with the DL-382 Gearbox and suspect an issue related to the auxiliary hydraulic pump or have had recent gearbox service, it is recommended to visit an authorized Audi service center. While this TSB does not typically stem from a direct customer complaint, a technician can check for the P17EF00 fault code in the vehicle's event memory.

Ensure that any repairs are performed by an authorized Audi dealer to maintain warranty validity and ensure the correct software update (SVM action code 02A223) is applied to the Transmission Electronics (J217) control unit. Inquire about the warranty coverage for this specific repair, especially if your vehicle is a high-voltage model or falls outside the standard warranty period.
