• The vehicle's gears cannot be selected.

Fault Codes / DTCs

When diagnosing the issue, technicians may find specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's control units. These codes indicate a problem with the gear selector lever system.

DTC Code	Diagnostic Address	Description	Symptom Code
P17E600	0081	Selector lever position sensor implausible signal	2003

Diagnosis / Trigger Conditions

The underlying cause for the "Audi A6 selector lever fault" and related DTCs is a voltage evaluation issue that leads to an event memory entry. This indicates an internal problem with how the vehicle's system monitors the gear selector lever's position and function.

Important Warnings for Owners

Owners should be aware of several critical points regarding this service action:

• High-Voltage Vehicle Precaution: For vehicles equipped with high-voltage components, the high-voltage charging cable MUST be unplugged before the SVM code is entered for the software update. Failure to do so can cause damage to the high-voltage components due to charging the battery during the update.
• No Reimbursement for Replaced Parts: Claims for replaced parts will not be reimbursed under this Technical Service Bulletin. The repair focuses solely on a software update.
• Third-Party Modifications: If non-genuine components or modifications have been carried out on the vehicle by third parties (e.g., tuning), neither Audi AG nor the dealership will accept liability for any damage caused by the software update or by failing to perform it. Technicians are instructed to ask customers about such modifications and note them on the job order.

Repair Procedure Summary

The resolution for the "Audi A6 selector lever fault" involves updating the software of the 0081 control unit, which is the Gear Selector Lever -J587-. This is performed using an SVM (Software Version Management) action code.
