2022-2026 Audi Door Lock Malfunction TSB 2063236/8

Audi has issued Technical Service Bulletin (TSB) 2063236/8 to address various complaints related to front and rear door lock malfunctions across several models from 2022 to 2026. This TSB, scheduled for release on April 10, 2025, provides guidance for diagnosing and resolving issues that can lead to doors not opening, warning messages, and specific diagnostic trouble codes (DTCs).

Symptoms

Owners of affected Audi vehicles may experience one or more of the following symptoms related to a 2023 Audi e-tron door lock fault or similar issues in other models:

• Front or rear doors (on either side) cannot be opened from the outside or the inside.
• Dashboard messages appear, such as those related to the "exit warning system" or "central locking."
• The vehicle appears locked, but a door can still be opened without using a key.
• Door locks are generally unresponsive or not working correctly.

Technicians have also noted that these issues can arise if the interior door handle is pulled too quickly or past its end stop. In some cases, the door may open if the interior handle is pulled twice, or if the exterior handle is used after that.

Fault Codes / DTCs

When a 2023 Audi e-tron door lock fault occurs, one or more of the following Diagnostic Trouble Codes (DTCs) may be logged in the vehicle's event memory:

Diagnostic Trouble Code	Fault Symptom	Storage State
B122D29	Lock unit for central locking implausible signal	Intermittent
B14FF29	Motor for child safety lock implausible signal	Intermittent
B122B13	Central locking motors Open circuit	Intermittent

Diagnosis / Trigger Conditions

The TSB outlines a detailed diagnostic process to identify the root cause of the door lock malfunction. This includes interviewing the customer to understand the exact nature of the complaint and how the issue manifests. Technicians are instructed to check if the interior door handle was pulled too quickly or past its end stop, as this can sometimes trigger messages or faults without an actual problem with the door lock.

Furthermore, the diagnostic procedure involves reading out and erasing event memory entries in the control unit. After cycling the ignition and operating the door, technicians recheck for fault entries. If no faults reappear, the door lock is considered functional.

Important Warnings / What Owners Should Know

Audi emphasizes that improper operation of the door handles, especially those equipped with a convenience key, can lead to unintended locking or unlocking. Owners should be aware of the following:

• For vehicles with a mechanical exterior door handle and convenience key (as shown in Figure 1 of the original document), to lock the vehicle, close the door and touch the sensor on the door handle once. Do not take hold of the door handle when doing so, otherwise the vehicle will not be locked.
• When opening the doors, care must be taken not to touch the sensor on the exterior door handle at the same time (e.g., with the thumb), as otherwise the vehicle will be locked again. This is considered incorrect operation by the user.
• Replacing parts or attempting repairs without taking this TSB into account will not fix the problem. Unjustified work or replacement parts will be charged back, and invoicing under warranty will not be permitted in such cases.

Repair Procedure Summary

Before any component replacement, technicians must perform a thorough check to ensure the complaint isn't due to incorrect operation. This involves:

1. Customer Interview: Clarifying the exact details of the complaint.
2. Operational Check: Verifying if the issue is related to how the interior handle is pulled (too quickly, past end stop) or if the door opens by pulling the interior handle twice or using the exterior handle.
3. Documentation Review: Consulting the Owner's Manual, Workshop Manual, and Guided Fault Finding (GFF) information.
4. Event Memory Management: Reading out event memory entries, erasing them, and then re-checking after an ignition cycle and door operation.
5. Mechanical Inspection: Checking the electrical wiring and mechanical Bowden cables at the door lock and handles for any damage, irregularities (e.g., twisting, incorrect routing, water/ice traces, stiffness). Affected components should be replaced if necessary.
6. Exterior Handle Check: Ensuring the exterior door handle returns to its flush original position. If not, refer to TSB 2060196, "57 Exterior door handles do not return to the zero position," for guidance on modification or replacement.
7. Door Setting Adjustment: Checking and adjusting the door setting for ease of movement and correct closing.

Only if the complaint persists and event memory entries are still logged after these checks should technicians proceed with further Guided Fault Finding steps.

Owner Action

If you are experiencing a 2023 Audi e-tron door lock fault or similar symptoms in your 2022-2026 Audi model, it is recommended to schedule an appointment with an authorized Audi service center. Inform them about the specific symptoms and any warning messages you have observed. While this TSB is informational for vehicles outside of warranty, repairs performed within the warranty period should be covered according to Audi's policies.
