2021-2024 Audi Q7/SQ7 Power Closing Door Latch Inoperative TSB

Symptoms

Owners of 2021-2024 Audi Q7 and SQ7 vehicles may experience an issue where the power closing door latch system intermittently does not work. This can be accompanied by the message: "The power closing door latch system intermittently does not work and the electronic parking brake warning is displayed in the instrument cluster."

Typically, the door may stop in the pre-latch position and fail to close fully using the power closing door system. Despite this, the door usually closes and latches properly when operated manually.

Diagnosis

Before proceeding with repairs for the Audi Q7 power closing door latch issue, technicians should verify that the door control modules have the latest software levels installed. This may involve checking other applicable Technical Service Bulletins, such as TSB 2051540.

The underlying cause is often insufficient counter-pressure on the door latch from the door or door seal. This lack of pressure prevents the door control module from receiving a reliable signal that the owner intends to close the door, leading to the door not closing properly. Notably, no specific Diagnostic Trouble Codes (DTCs) are typically stored in the door control modules for this condition.

Repair Procedure Summary

The repair for the intermittent Audi Q7 power closing door latch problem, as detailed in Audi TSB 2058159/5, begins by ensuring all door control modules are updated with the most current software.

If the issue persists, the technician will inspect and adjust the door striker. This involves centering the striker to the latch and then adjusting it inward by at least 0.5 mm. After this adjustment, the front door should remain flush or slightly under flush with the rear door.

Following the striker adjustment, the power closing door latch system's functionality is rechecked. If the problem is resolved, no further steps are necessary. If the issue continues, the outer door seal will be replaced. The new outer door seal is installed with a 1.0 mm inward offset compared to the original seal's position, and technicians are advised to mark the original seal's position before removal.

Required Tools or Parts

To address the Audi Q7 power closing door latch concern, specific parts may be required:

• Front outer door seal: Part Number 4M0837911C (Quantity 0-2)
• Rear outer door seal: Part Number 4M0839911C (Quantity 0-2)

Additionally, fasteners, bolts, nuts, and screws may be needed, and technicians should refer to ETKA/ELSA for specific requirements.

Important Warnings

Audi states that if your 2021-2024 Audi Q7 or SQ7 vehicle is outside of its warranty period, this Technical Service Bulletin 2058159/5 is provided for informational purposes only. Owners whose vehicles are no longer under warranty may be responsible for the cost of any necessary repairs.
