Documentation required

Technical Background

The control unit detects excessive force at the buffers.

Production Solution

Part optimization and process change in week 40/2025.

Service

This measure consists of 4 steps that must all be performed:

1. Check whether the software update is available:

Please perform the software update described in TSB 2079690, 00 Combined software update 03.10.00/C
(28.13.01) KD2.

The vehicle already has the optimized software if the diagnostic address 0046 has software version 0231 or higher.

The software update simply increases robustness. The rear lid MUST be adjusted mechanically to the correct
position according to the instructions below.

2. Check the part number of the bump stop:

Make sure the new side bump stop (Figure 1) with part number 85J.827.249.A is fitted to 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
adjustment buffer 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.

Figure 1. Pre-tensioned bump stop with optimized spring without index A, marked by a white dot.

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

Remove the side bump stops (pre-tensioned spring buffers, Figure 2). Using the Workshop Manual, spring force
gauge VAS 895 035 and measurement film VAS 895 037, adjust the rear lid buffer force to between 40 N and 60 N
and then fit the pre-tensioned spring buffers again.

Figure 2. Pre-tensioned bump stop/spring buffer.

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) (Figure 3).

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 the vehicle is not equipped with side bump stops, 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 the rear lid:

©

It is imperative to reset initialization (basic settings) 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.

Open the rear lid so that you can reach the inner and outer electric rear lid actuation buttons.

Press and hold the electric rear lid lock actuation button on the outside (Figure 4) and the electric rear lid lock
actuation button on the inside (Figure 5, item 3) simultaneously for at least 5 seconds. An audible signal will be
given.

Then open and close the rear lid three times using the two buttons. Make sure that the rear lid reaches the end
positions each time.

The vehicle confirms the end position with an acoustic signal.

Ay caution

It is essential not to hinder or stop the movement of the rear lid under any circumstances. This interrupts
the initialization process.

Ay caution

Anti-trapping function is not active during the initialization process. Make sure that there is no risk of
entrapment for you or other people at any time.

The initialization process is now complete.

An example of the procedure is shown in the video by scanning the QR Code below (Figure 6):

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 under point 4.

When billing, please always attach videos 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 face, license plates, or customer
data.
