2021-2026 Audi Q7/SQ7 Power Closing Door Latch Inoperative TSB

Audi has issued Technical Service Bulletin (TSB) 2058159/7 to address concerns regarding the power closing door latch system in 2021-2026 Audi Q7 and SQ7 vehicles. Owners may experience the power closing door latch system intermittently not working, accompanied by an "electronic parking brake warning is displayed in the instrument cluster."

This bulletin, released on March 10, 2026, provides diagnostic and repair procedures for technicians to resolve the Audi Q7 power closing door latch problem. It supersedes previous revisions, with the latest update adding model year 2026 to the affected range.

Symptoms

Owners of affected Audi Q7 and SQ7 models may observe the following symptoms related to the Audi Q7 power closing door latch system:

• The power closing door latch system intermittently does not work.
• An "electronic parking brake warning is displayed in the instrument cluster."
• The door striker may stop in the pre-latch position, preventing the door from fully closing via the power closing system.
• Despite these issues, the door typically closes and latches properly when manually shut.

Fault Codes / DTCs

According to TSB 2058159/7, technicians should note that no relevant Diagnostic Trouble Codes (DTCs) are typically stored in the door control modules when this specific condition occurs.

Technical Background

The root cause of the intermittent power closing door latch issue lies in the interaction between the door latch and the door striker. The door latch relies on adequate counter-pressure from the door or door seal to generate a reliable signal for the door control module. If the door striker is not adjusted correctly, it may not provide sufficient counter-pressure for the latch mechanism.

This lack of proper counter-pressure prevents the door control module from recognizing the door latch signal for a long enough duration, or at all. Consequently, the door fails to close automatically. Audi is gradually implementing a production solution to address this concern in new vehicles.

Repair Procedure Summary

Before performing any repairs, technicians must first check for and install any applicable software updates for the door control modules. This includes ensuring the latest software levels, such as versions 0060, 0130, or higher, are installed. TSB 2051540, which also addresses the Audi Q7 power closing door latch issue for MY18, may be relevant for software updates.

If the concern persists after software updates, the following steps are performed:

1. Door Striker Alignment Check: The technician will inspect the alignment of the door striker to the latch and make any necessary adjustments to center the striker.
2. Door Striker Adjustment: The door striker will be adjusted inward as far as possible, by at least 0.5 mm. This adjustment aims to increase the counter-pressure for the door latch. The front door may appear flush or slightly under flush to the rear door after this adjustment, which is considered normal and should not cause wind noise.
3. Functionality Recheck: After adjusting the striker, the power closing door latch system's functionality is rechecked. If the door closes properly, no further repairs are needed.
4. Outer Door Seal Replacement (If Needed): If the issue continues, a new outer door seal will be installed. This new seal has an inward offset of 1.0 mm compared to the original seal's location, further enhancing the counter-pressure required for proper door latch operation.

Required Parts and Tools

For repairs involving the replacement of door seals, technicians may require the following parts:

• Front outer door seal (Quantity 0-2)
• Rear outer door seal (Quantity 0-2)

Specific part numbers should be obtained from ETKA or the Parts Department for the latest information.

Important Warnings

Owners should be aware that if their vehicle is outside of its warranty period, this Technical Service Bulletin is for informational purposes only. Warranty claims related to this TSB, including Damage Code 0016 and Service Numbers 5741 and 5841, must adhere to the Audi Warranty Policies and Procedures Manual.

Owner Action

If you are experiencing issues with your Audi Q7 power closing door latch system or an "electronic parking brake warning is displayed in the instrument cluster" in your 2021-2026 Audi Q7 or SQ7, it is recommended to contact an authorized Audi dealership. They can diagnose the problem and perform the necessary adjustments or replacements as outlined in TSB 2058159/7.
