Customer states:
The rear lid does not close and opens again.
Workshop findings:
The rear lid does not close and opens again.
The closing process is cancelled before reaching the first closure plate and the rear lid opens again.
Documentation necessary
Technical Background
The control unit may detect excessive force at the bump stops.
Production Solution
Part optimization and process change in week 40/2025.

The measure consists of 4 steps that must all be performed:
1. Check whether Software update is available:
First check the software version in diagnostic address 0046.
If software version 0231 or higher is installed in diagnostic address 0046, this TSB must not be used. Please refer
to TSB 2080913, 55 Rear lid does not open or close fully (software version 0231 on DA 0046) in this case.
If the software version is below 0231, check whether TSB 2079690, 00 Combined software update 03.10.00/C
(28.13.01) KD2 is visible for this vehicle. If this is the case, please perform the software update described in TSB
2079690.
The software update simply increases robustness. The rear lid must be adjusted correctly using the following
instructions.
2. Check part number of bump stop:
Make sure the new side bump stop (see Figure 1) with part number 85J 827 249 Ais fitted on the vehicle. The
spring preload is reduced on this part. If the old bump stop 85J 827 249 is fitted on the vehicle, replace it with the
new bump stop with index A.
In autumn 2025, optimized buffers were already installed in vehicles that did not yet carry an index A. This buffer can
be identified by a white dot on the back. These buffers can also remain fitted in the vehicle.

3. Check mechanical setting of rear lid:
Then proceed as follows:

+ Remove the side bump stops (pre-tensioned spring buffers, see image 2). Using the Workshop Manual, spring
force gauge VAS 895 035 and measurement film VAS 895 037, adjust the buffer forces of the rear lid bump
stops to between 40 N and 60 N and then refit the bump stops. Alternatively, you can leave the side bump stop
installed and set the buffer forces to the lower limit of 40 N. Please also observe the Special Technical Service
Training video on the spring force gauge VAS 895 035 in the Audi Knowledge Tank (AKT). In addition, make
sure that the striker is positioned correctly and enters the lock in the center. Incorrect positioning can also
cause the rear lid to reverse direction. NOTE: If your vehicle is not equipped with side bump stops (see image
2), please start from the point: “Adjusting buffer forces using spring force gauge VAS 895 035”.

+ Then reset initialization of the rear lid and then adapt the flap opening angle again. Proceed as follows:

4, Initialize rear lid:

It is imperative to reset initialization of the rear lid and then adapt it again. If this is not performed, the

parameters logged in the control unit no longer match the preload of the rear lid and a repeat repair may

be required.

To do so, start diagnosis via Guided Functions and perform the function “0046 - Rear lid electronics - basic
setting”.
Ay caution
It is essential not to hinder or stop the movement of the rear lid under any circumstances. This interrupts
the initialization process. Furthermore, the roll-back function is not active during the initialization
process. Make sure that there is no risk of trapping you or other people at any time.
If the complaint still occurs:
Check the position of the striker and push it outwards slightly if necessary (ensure the rear lid fits properly). Another
initialization run for the rear lid is then required as per the procedure described above.

When billing, please always attach a video that clearly show the complaint to DOC-IT. To ensure a reference to the
vehicle, the video must:
+ Include the VIN and date.
+ Must not be edited.
+ Should be in focus and taken with sufficient light. A high resolution is not necessary.
If appropriate, please mark the location of the problem so that parts analysis has a clear reference to the complaint.
Please ensure that the video documentation does not show any people and/or faces, license plates, or customer
data.
