Technical Service Bulletin
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 in CW09/2022.
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:
The following questions are helpful to determine if an incorrect operation is causing the concern:
• Does the concern occur when the ignition is on or off (did the bus go to sleep when opening the door)?
• 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.

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.
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 aforementioned steps and if the
affected vehicle is produced before CW09/2022, replace the door latch.
