Technical Service Bulletin
• DTC B14FF29 (Child safety lock motor Implausible signal).
• DTC B122B13 (Central locking motors Open circuit).

Technical Background
The Audi A8 (D5) is equipped with fully electric door locks (aka “e-lock”). The micro switches are located at
the inner and outer door handles. The Audi A6/A7 (C8), Q8, Audi e-tron and e-tron GT models are equipped
with semi-electric door locks. The micro switches are integrated into the door locks and are not located at
the door handles.
The main difference between fully and semi-electric door locks is the location of the micro switches.
The request to open the door from the inner or outer door handle is transmitted electrically from the
respective micro switch to the door control module. The door control module triggers an electric motor within
the door lock, which releases the rotary latch, opening the lock. The door can be opened with very little
effort.
In addition, two Bowden cables are used to provide a mechanical connection between the door lock and the
inner/outer door handles. To open the door mechanically from the inside (in the event of an electrical
malfunction), the inner door handle must be pulled twice past the normal angle of operation. Opening the
door mechanically from the outside handle is only possible after the door lock cylinder or the inner door
handle were operated.

Production Solution
Improved door locks in series production.

Service
Tip: For customer concerns described in this TSB, do not replace the door lock immediately!
1.

Determine if the concern is caused by incorrect operation.

2.

Explain the functions of the electric door lock to the customer with reference to the Owner's
Manual:

Technical Service Bulletin
The following questions are helpful to determine if an incorrect operation is causing the
concern:
• Is the inner door handle pulled too quickly or pulled all the way to the stop?
• Does the door open if you pull the inner door handle twice? Afterward, can you open the door
with the outer door handle?
• How does the vehicle behave compared to a similar vehicle?
3.

The corresponding information in the Owner’s Manual, Repair Manual, in Guided Fault Finding,
and in TSB(s) should also be considered.

4.

5.

Interrogate the door control module fault memory of any affected door(s).

6.

Delete fault memory if any of the DTC(s) are stored. Perform ignition cycle. Open and close the
affected door(s).

7.

Re-check the fault memory of affected door control module(s).

8.

If the DTC(s) do not return and the door(s) can be opened/closed as designed the door latch is
OK.

Technical Service Bulletin
9.

If the DTC(s) return and/or the door latch does not operate as designed, inspect the door wire
harness and the Bowden cables, especially the connections at the door lock and the inner and
outer door handles for any issues (twisting, loose connection, routing, damage, traces of
water/ice, stiffness, etc.).

10. Replace any defective components as necessary.
11. Check if the outer door handles return flush to the zero/rest position.
12. If they do not, follow TSB 2060196: 57 Exterior door handles do not return to the zero position to
modify the outer door handles as necessary.
13. Check if the doors open/close freely and latch/unlatch smoothly.
14. Adjust the striker plate, door alignment, and/or door hinges as necessary.

If the customer complaint can be reproduced after performing the above steps, replace the
door latch.
