2023-2026 Audi e-tron Door Lock Malfunction TSB

Owners of various Audi models, including the 2023-2026 Audi e-tron, may encounter issues with their vehicle's front or rear door locks. These problems can manifest as doors that cannot be opened from either the inside or outside, or as warning messages appearing on the instrument cluster. Audi has released Technical Service Bulletin (TSB) 2063236/6 to address these concerns, providing detailed diagnostic and repair instructions for technicians.

This TSB, identified as 57 24 58 2063236/6, supersedes previous bulletin Group 57 number 24-31 dated February 15, 2024. The update, released on August 30, 2024, includes revisions to the title, header, condition, technical background, production solution, service, warranty, and additional information sections.

Symptoms

Owners may notice several symptoms indicating an Audi door lock malfunction. The primary complaint is that the front or rear door, on either the left or right side, cannot be opened using the interior or exterior handle. Additionally, drivers might see warning messages related to the door system, such as those for the "exit warning system" or "central locking."

In some cases, the vehicle may appear locked, but a door can still be opened without using a key, pointing to an underlying issue with the door lock mechanism. Workshop technicians have also reported that door locks simply do not work and that various images indicate a problem with the door lock.

Fault Codes / DTCs

When diagnosing an Audi door lock malfunction, technicians may find one or more of the following Diagnostic Trouble Codes (DTCs) logged in the vehicle's event memory:

Diagnosis and Trigger Conditions

Before replacing any door lock components, technicians are advised to first check for incorrect operation by the customer. This includes situations where the interior door handle is pulled too quickly or past its end stop, which can generate messages or faults without an actual door lock problem. Technicians should also verify if the door opens by pulling the interior handle twice or by using the exterior handle, as this might indicate no fault in the door lock.

Further diagnostic steps involve reading and erasing event memory entries from the control unit. After erasing, the ignition should be cycled, the door opened and closed, and then rechecked for re-logging faults. If the event memory entry does not re-log, the door lock is considered functional. A mechanical inspection of the electrical wiring and Bowden cables at the door lock and door handles is also crucial to identify any damage, twisting, incorrect routing, or signs of water/ice. If the exterior door handle does not return to its flush original position, reference TSB 2060196, "57 Exterior door handles do not return to the zero position," for further guidance.

Repair Procedure Summary

The repair process for an Audi door lock malfunction begins with thorough diagnosis as described above. If, after all inspection work, the complaint persists or event memory entries continue to be logged, the affected door lock should be replaced according to the Workshop Manual. The TSB emphasizes the importance of verifying correct door setting and adjusting it if necessary to ensure ease of movement and proper closing.

Required Tools or Parts

To perform the diagnostic and repair procedures outlined in TSB 2063236/6, technicians will require specific equipment:

• VAS 6160/VAS 6150: A VAS tester equipped with the current version of ODIS (Windows 10).

Important Warnings

Owners should be aware that if their vehicle is outside of its warranty period, this Technical Service Bulletin is provided for informational purposes only. The repair may not be covered under warranty in such cases.

Owner Action

If you are experiencing an Audi door lock malfunction or seeing related warning messages or DTCs like B122D29, B14FF29, or B122B13, it is recommended to schedule an appointment with an authorized Audi service center. They have the necessary tools and information, including TSB 2063236/6, to properly diagnose and repair the issue.
