Symptoms

Owners of 2021-2022 Audi Q7, SQ7, and A4 allroad vehicles may experience issues with their power tailgate. The most common complaints include the power tailgate not opening or closing, or the power tailgate cannot be opened or closed electronically. If you are experiencing an Audi power tailgate not opening, this TSB may apply to your vehicle.

Fault Codes / DTCs

When diagnosing the power tailgate issue, technicians may find the following Diagnostic Trouble Code (DTC) stored in the rear lid control module, J605 (address word 006D):

This DTC can appear as active/static or passive/sporadic, indicating a persistent or intermittent fault with the hall sensors in the rear lid motor.

Technical Background

The root cause of the Audi power tailgate not opening issue is an overly sensitive error detection system for the rear lid motor's hall sensor. This sensitivity causes the system to incorrectly store DTC B121102, even when there might not be a physical malfunction.

Production Solution

Audi addressed this condition in series production during the fourth quarter of 2021. A new Target Data Container (ZDC) update for the rear lid control module, J605, was implemented to resolve the sensitive error detection.

Repair Procedure Summary

To resolve the power tailgate malfunction and address the Audi power tailgate not opening condition, Audi Technical Service Bulletin 55 22 67 2066057/1 outlines a software update procedure. This involves updating the rear lid control module, J605, using the Software Version Management (SVM) system.

1. Reference SVM Instructions: Technicians must first follow the instructions detailed in TSB 2011732: 00 Software Version Management (SVM), operating instructions.
2. Update Rear Lid Control Module: The J605 control module (address word 006D) needs to be updated using the SVM action code 6DA006. The TSB specifies target data container numbers for different models and years, such as 8W0909541G for A4 allroad and 4M0909541P for Q7/SQ7, with corresponding software versions 0030 and 0036 or higher.
