2021-2022 Audi Q7 Power Closing Door Latch Inoperative TSB

Audi has issued Technical Service Bulletin (TSB) 2058159/3 to address an issue with the power closing door latch system in 2021-2022 Audi Q7 models. Owners may experience an intermittently inoperative power closing door latch, which can be accompanied by an electronic parking brake warning in the instrument cluster. This TSB provides a detailed repair procedure for technicians to resolve the concern.

The TSB 2058159/3, dated September 15, 2021, supersedes an earlier bulletin, Group 57 number 20-64, which was dated February 6, 2020. The updated bulletin includes revised header information and added model years 2020-2022, along with revised condition details.

Symptoms

Owners of affected Audi Q7 vehicles may report that "The power closing door latch system intermittently does not work and the electronic parking brake warning is displayed in the instrument cluster." Despite this, the door typically still closes and latches properly. Workshop findings indicate that the door striker often stops in the pre-latch position, preventing the power closing system from fully engaging the door. Importantly, no relevant Diagnostic Trouble Codes (DTCs) are usually stored in the door control modules for this specific issue, making the "Audi Q7 power closing door latch inoperative" symptom the primary indicator.

Diagnosis / Trigger Conditions

The technical background for this issue explains that the door latch requires sufficient counter-pressure from the door and door seal to generate a reliable signal for the door control module. If the door striker is adjusted in a way that does not provide enough counter-pressure, the door control module may not recognize the door latch signal long enough, or at all. This prevents the door from closing correctly via the power closing system.

Repair Procedure Summary

Before performing any repairs outlined in TSB 2058159/3, technicians are instructed to check for and apply any applicable software updates, such as those mentioned in TSB 2051540, to ensure the door control modules have the latest software levels. If the customer concern persists after software updates, the following steps are performed:

1. Striker Alignment Check: The door striker to latch alignment is checked, and any necessary adjustments are made to center the striker to the latch.
2. Inward Striker Adjustment: The door striker is adjusted inward by at least 0.5 mm. The front door can be flush or slightly under flush to the rear door, ensuring no wind noise is created.
3. Functionality Recheck: After striker adjustment, the power closing door latch system's functionality is rechecked. If the door now closes properly, no further repairs are needed.
4. Outer Door Seal Replacement (If Necessary): If the problem with the Audi Q7 power closing door latch inoperative condition continues, a new outer door seal is installed. This new seal is positioned with an inward offset of 1.0 mm compared to the original location. Technicians are advised to mark the original seal position before removal.
