2021 Audi A6 Selector Lever Fault TSB

Audi has released Technical Service Bulletin (TSB) 37 24 23 2074733/2 to address issues related to a "Selector lever fault" message appearing in the instrument cluster of certain 2021 Audi models. This bulletin, dated August 27, 2024, supersedes an earlier TSB, Group 37 number 24-10, from July 31, 2024, and includes revised header information and adjusted SVM table details. The primary concern for owners is the inability to select gears, which is a significant safety and operational problem for the 2021 Audi A6 selector lever fault.

Symptoms

Owners of affected vehicles may observe the following symptoms:

• A "Selector lever fault" message displayed prominently in the instrument cluster.
• An inability to select gears, preventing the vehicle from being driven normally.

Fault Codes / DTCs

When diagnosing the 2021 Audi A6 selector lever fault, technicians may find specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's control units. These codes indicate the nature of the fault:

• From Gear Selector Lever -J587- (diagnostic address 0081):
  • P17E600: "Selector lever position sensor implausible signal"; symptom 2003
  • P091900: "Selector lever error"; symptom 5031
  • P18CB00: "Button for parking lock implausible signal"; symptom 3003
• From Transmission Control Module (TCM) -J217- (diagnostic address 0002):
  • P085D00: "Selector lever malfunction"; symptom 22351

Diagnosis

This issue, which leads to the "Selector lever fault" message, is triggered by an event memory entry resulting from a diagnosis of voltage evaluation. When a vehicle presents with the described symptoms, technicians will connect to the vehicle's diagnostic system to confirm the presence of these specific DTCs in either the Gear Selector Lever -J587- or the TCM -J217- control units. The presence of these codes confirms the need for the software update outlined in TSB 37 24 23 2074733/2.

Important Warnings

Owners and technicians should be aware of several critical warnings associated with this service bulletin:

• High-Voltage Vehicle Precaution: For Audi models equipped with high-voltage components (such as the A7 e quattro), it is absolutely essential to unplug the high-voltage charging cable before entering the Software Version Management (SVM) code for the software update. Failure to do so could result in the high-voltage battery charging during the update process, which can cause severe damage to the high-voltage components.
• Non-Genuine Parts or Modifications: Audi of America, Inc. and its authorized service centers will not accept liability for any damage that may occur from updating the software, or from failing to do so, if non-genuine components have been retrofitted to the vehicle or if third-party modifications (e.g., performance tuning) have been carried out and not properly documented. Customers will be asked about any such modifications, and this information must be noted on the job order.
• No Reimbursement for Replaced Parts: Audi explicitly states that claims for replaced parts will not be reimbursed under the terms of this Technical Service Bulletin. The specified repair is a software update, not a component replacement.

Repair Procedure Summary

The recommended repair for the 2021 Audi A6 selector lever fault and related DTCs is a software update to the Gear Selector Lever -J587- control unit (diagnostic address 0081). Technicians are instructed to follow the detailed operating instructions provided in TSB 2011732, titled "00 Software Version Management (SVM)". The update process involves using a specific SVM action code to install the latest software version. After the software update, it is crucial to reconfigure various other control units in the vehicle. This ensures they function correctly and communicate properly with the newly updated gear selector lever control unit, maintaining overall vehicle system integrity.

Required Software/Parts

This repair primarily involves a software update. The new software part numbers will replace older versions to resolve the issue. For example, the new software part number 4K1713041M will replace previous versions like 4K1713041H or 4K1713041K for 2019-2021 A6/A7 models. For S6/RS6 models, the new software is 4K1713041J, and for S7/RS7 models, it is 4K1713041L.

Owner Action

If your 2021 Audi A6, A7, S6, S7, RS 6 Avant, A7 e quattro, or RS 7 displays a "Selector lever fault" message or you experience difficulty selecting gears, it is recommended to contact your authorized Audi dealer. Inform them of the symptoms and mention Technical Service Bulletin 37 24 23 2074733/2. The software update is generally covered under warranty. However, if your vehicle is outside of its warranty period, this bulletin serves as informational guidance for the repair. Be prepared to discuss any non-genuine parts or aftermarket modifications on your vehicle, as this information is important for the repair process and potential liability.
