2021-2025 Audi Q7/SQ7 Power Closing Door Latch Issue TSB

Audi has issued Technical Service Bulletin (TSB) 57 24 45 2058159/6 to address an intermittent power closing door latch issue affecting certain 2021-2025 Audi Q7 and SQ7 vehicles. This bulletin, dated June 17, 2024, supersedes previous TSB 23-10 from June 13, 2023, and provides updated guidance for diagnosing and resolving the problem. Owners experiencing a malfunctioning power closing door latch system should be aware of this important information.

Symptoms

Owners of affected 2021-2025 Audi Q7 and SQ7 vehicles may notice that the "power closing door latch system intermittently does not work." This can be accompanied by an "electronic parking brake warning is displayed in the instrument cluster." Despite these warnings, the door typically closes and latches properly otherwise.

During workshop inspections, technicians have observed that the door striker may stop in the pre-latch position. This prevents the door from being fully closed by the power closing door system. It's important to note that no relevant Diagnostic Trouble Codes (DTCs) are stored in the door control modules for this specific condition.

Diagnosis and Technical Background

The root cause of the intermittent power closing door latch issue lies in the door latch's requirement for adequate counter-pressure from the door or door seal. This pressure is crucial for generating a reliable signal to the door control module, indicating the driver's intent to close the door. If the door striker is misadjusted, it may not provide sufficient counter-pressure for the latch. Consequently, the door control module might not recognize the door latch signal for a long enough duration, or at all, leading to the door not closing properly.

Important Warnings

Before any repairs are performed, technicians must check for and install the latest door control module software. This is outlined in applicable TSBs, such as TSB 2051540, which specifically addresses power closing door latch issues for earlier model years. Ensuring the software is up-to-date is a prerequisite before proceeding with any mechanical adjustments detailed in TSB 57 24 45 2058159/6.

Repair Procedure Summary

The repair procedure for the intermittent power closing door latch issue involves a series of diagnostic and adjustment steps:

1. Software Update Check: Verify that the door control modules have the latest software levels installed, referencing other applicable TSBs like 2051540.
2. Striker Alignment and Adjustment: The door striker to latch alignment must be checked and adjusted to ensure it is centered. Simultaneously, the door striker should be adjusted inward by at least 0.5 mm.
3. Functionality Recheck: After adjusting the door striker, the power closing door latch system's functionality is rechecked. If the door now closes properly, no further repairs are necessary.
4. Outer Door Seal Replacement (If Needed): If the concern persists after striker adjustment, a new outer door seal must be installed. This new seal should be positioned with an inward offset of 1.0 mm compared to the original seal location. Technicians are advised to mark the original seal's position before removal.

Required Parts and Tools

For this repair, specific parts and fasteners may be required:

• Fasteners, Bolts, Nuts, and Screws: As needed per the repair manual (refer to ETKA).
• Front outer door seal: Part Number 4M0837911C.
