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, and Audi e-tron models are equipped with semielectric 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.

Technical Service Bulletin
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
Not Applicable.
Service
Tip: For customer concerns described in this TSB, do not replace the door lock immediately! Follow
the diagnostic tree starting at the top to determine the root cause (Figure 1).

Technical Service Bulletin
Figure 1. Follow the diagnostic tree starting at the top.
Operating Error:
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.
4. For further information, please review the information video
regarding door handle operation at https://audiexternal.kzoplatform.com/player/medium/2084964271170524781.

Electrical Error
A6, A7, A8, and Q8:
1. Follow TSB 2055932: 57 Central locking/parking brake warning, alarm or exterior mirror issues, DTCs
B122D29, B14FF29 or U122800 stored to ensure that the door control modules are at the latest software
level and update them if necessary or applicable.
Audi e-tron quattro and Audi e-tron sportback quattro:
1. Follow TSB 2055933: 57 Exit warning message with various central locking & alarm issues, DTCs
B122D29, U122800, and/or B14FF29 stored to ensure that the door control modules are at the latest
software level and update them if necessary or applicable.
All models:
2. Interrogate the door control module fault memory of any affected door(s).
3. Delete fault memory if any of the DTC(s) are stored. Perform ignition cycle. Open and close the affected
door(s).
4. Re-check the fault memory of affected door control module(s).
5. If the DTC(s) do not return and the door(s) can be opened/closed as designed the door lock is
electrically OK. Follow the section “Mechanical Error” in this TSB and continue to observe for new DTC
entries.
6. If the DTC(s) cannot be deleted or return, observe the following measuring value blocks for plausible
conditions while opening/closing the door(s):

Tip: After pulling the inside or outside door handle, the electric motor in the door lock starts to release
the rotary latch. Until the rotary latch has been completely released, the value of “Status Door Lock”/ID
MAS06256 is temporarily “implausible.”
7. If any of the measuring value blocks are implausible, measure the resistance directly using the
multimeter function of the VAS tester:
A6, A7, Q8, Audi e-tron quattro, Audi e-tron quattro sportback quattro, and Audi e-tron GT (models
with semi-electric door lock):
•
At PIN #2 and PIN #4 of the door lock (ohms reading of emergency unlock switch, inner and outer
door handle switches connected in parallel).
A8 (models with electric door lock):
• At PIN #2 and PIN #4 of the door lock (ohms reading of emergency unlock switch).
• At inner and outer door handles (ohms reading of inner or outer door handle switches).
8. Compare readings with the specifications in the table below:

9.
Readings of 1,000, 382, 212, and 158 ohms indicate that the emergency unlock function is active and
that the door lock can only be released mechanically. In this case, pull the inner door handle twice to
its stop. Then close the door, open it again and repeat the measurement. It should now read OL
(overload) if the inner and/or outer door handles are not operated.
10.
If the measurements are according to specifications, do not replace the door lock as it is not the root
cause of the customer’s concern.
11.
Visually and electrically check the PINs at the door lock and the door control module and the
connecting wiring.
12.
Check the wiring and connections at the door coupling points at the A-pillar and B-pillar.
Mechanical Error:
1.
Inspect 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.).

2.
Replace any defective components as necessary.
3.
Check if the outer door handles return flush to the zero/rest position.
4.
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.
5.
Check if the doors open/close freely and latch/unlatch smoothly.
6.
Adjust the striker plate, door alignment, and/or door hinges as necessary.
Tip: Parts replacement, without following this TSB, does not resolve this issue. Claims for replaced
parts will be subject to review.
