2019-2024 Audi Door Lock Malfunction TSB 2063236/5

Audi has issued Technical Service Bulletin (TSB) 57 24 31 2063236/5 to address concerns regarding front or rear door locks that are not locking, are without function, or display fault messages in the Driver Information System (DIS). This TSB, dated February 15, 2024, supersedes previous bulletin Group 57 number 23-09 dated June 7, 2023, and applies to a wide range of Audi models from 2019 to 2024, including the Audi e-tron door lock system.

This bulletin provides comprehensive guidance for technicians to diagnose and resolve door lock issues, ensuring proper operation and addressing associated diagnostic trouble codes (DTCs). The TSB has undergone several revisions, with the latest (Revision 5) adding model years, modifying production and service solutions, and updating warranty information. Revision 4 (June 7, 2023) removed model years and electrical measurements, while Revision 3 (June 8, 2022) updated warranty details, parts, tools, and additional information references.

Symptoms

Owners may notice several symptoms indicating a door lock malfunction. These include the front and/or rear doors being unable to be opened from either the outside or the inside. Fault messages related to the door system may appear in the Driver Information System (DIS), such as examples like "exit warning," "central locking," or "child safety lock."

Additionally, doors might be locked but one can still be opened without a key. The door closing assist feature may also be inoperative or operate intermittently. These issues can affect the functionality and security of the Audi e-tron door lock system and other models.

Fault Codes / DTCs

Technicians diagnosing these door lock issues may find one or more of the following Diagnostic Trouble Codes (DTCs) stored in the respective door control modules:

Code	Description	Control Module
B122D29	Lock unit for central locking Implausible signal	Driver's door control module (-J386-, address word 0042), Passenger's door control module (-J387-, address word 0052), Rear driver side door control module (-J926-, address word 00BB), Rear passenger side door control module (-J927-, address word 00BC)
B122B13	Central locking motors Open circuit	Driver's door control module (-J386-, address word 0042), Passenger's door control module (-J387-, address word 0052), Rear driver side door control module (-J926-, address word 00BB)
B14FF29	Child safety lock motor Implausible signal	Rear driver side door control module (-J926-, address word 00BB), Rear passenger side door control module (-J927-, address word 00BC)

Diagnosis and Trigger Conditions

Audi's door lock systems vary; the Audi A8 (D5) uses fully electric door locks, while models like the A6/A7 (C8), Q8, Audi e-tron, and e-tron GT utilize semi-electric door locks. The primary difference lies in the micro switch location. In semi-electric systems, these switches are integrated into the door locks, not the door handles.

When a door handle is operated, an electrical signal is sent to the door control module. This module then activates an electric motor within the door lock to release the latch. Mechanical cables also provide a backup for opening the door. To open a door mechanically from the inside during an electrical malfunction, the inner door handle must be pulled twice past its normal operating angle.

Initial diagnostic steps involve determining if the concern is due to incorrect operation. Technicians should ask the customer if the inner door handle was pulled too quickly or fully to the stop, if the door opens after pulling the inner handle twice, and how the vehicle's behavior compares to a similar vehicle. The Owner's Manual and an information video on door handle operation (accessible via QR code or link) should be referenced. Figure 2 in the TSB provides a QR code for viewing this supporting video on phones and tablets, which can also be accessed via a direct link.

Important Warnings

When addressing customer concerns described in this TSB 57 24 31 2063236/5, technicians are advised: Do not replace the door lock immediately! Thorough diagnostic steps must be followed first to avoid unnecessary part replacement.

Repair Procedure Summary

1. Initial Assessment: Determine if the issue is caused by incorrect operation. This involves asking the customer specific questions about door handle usage and consulting the Owner's Manual, Repair Manual, Guided Fault Finding, and other relevant TSBs.
2. Information Video Review: Review the information video regarding door handle operation, accessible at https://audi-external.kzoplatform.com/player/medium/2084964271170524781.
3. Fault Memory Check: Interrogate the fault memory of any affected door control module(s).
4. Clear and Re-check: Delete any stored DTCs, perform an ignition cycle, and open and close the affected door(s). Re-check the fault memory of the affected door control module(s).
5. Functionality Check: If the DTCs do not return and the door(s) can be opened and closed as designed, the door latch is considered OK.
6. Wiring and Cable Inspection: If DTCs return and/or the door latch does not operate as designed, inspect the door wire harness and the Bowden cables. Pay close attention to connections at the door lock and the inner and outer door handles for any issues such as twisting, loose connections, improper routing, damage, traces of water/ice, or stiffness.
7. Component Replacement: Replace any defective components identified during the inspection.
8. Outer Door Handle Check: Verify that the outer door handles return flush to the zero/rest position.
9. External TSB Reference: If the outer door handles do not return flush, follow TSB 2060196: "57 Exterior door handles do not return to the zero position" to modify the outer door handles as necessary.
10. Door Operation Check: Check if the doors open and close freely and latch and unlatch smoothly.
11. Adjustment: Adjust the striker plate, door alignment, and/or door hinges as necessary.
12. Final Action: If the customer complaint can still be reproduced after performing all the above steps, only then should the door latch be replaced.

Required Tools

Technicians will require a VAS tester with the current version of ODIS (Windows 10). Specifically, the VAS 6160 or VAS 6150 tools are listed.
