Interference Noises During Calls

MODEL
E-Series
G09

Model Description
BMW XM Sports Activity Vehicle

Affected Option Code
Without SA 5AX – Highway
Assistant

SITUATION
When making a call through the vehicle systems with a connected mobile device, electrical interference
noise from accelerating or braking is heard by the other party (recipient). No interference can be heard in the
vehicle.

CAUSE
Interference on the ground circuit of the TCB4 (WAVE-01).

CORRECTION
Install a new ground point for the Vehicle Dynamics Platform (VDP) module.

PROCEDURE
Note: Before performing this retrofit/installation repair procedure and submitting a claim, first
review the Repair History (Claims) section below in the Warranty Vehicle Inquiry (WVI) to confirm
that a prior claim for this retrofit/installation repair procedure has not already been submitted and
accepted.
Because of the Emergency Call function, the continuity of the driver’s microphone is evaluated by the TCB4
control unit using the ground circuit as a reference. The TCB4 and the VDP control unit share a ground point
at ground comb Z10*8B.
The activation of the vehicle dynamics systems by the VDP causes interference frequencies on the ground
comb which is shared by the TCB4. These interference frequencies affect the TCB4 and are perceived as
audible interference noises in the microphone circuit. This is why only the recipient can hear the interference
during a call.
Note: This procedure only refers to interference heard by the recipient. Any other type of
interference must be diagnosed separately.
The first step is to verify the interference is truly caused by the VDP module. The following steps are
necessary to prove the VDP module is the cause of the complaint:
1. Verify the issue is currently present by initiating a phone
call during test drive with a paired mobile device. During the
call, the call recipient must report that interference in
present on the call.

2. Next, remove fuse F224 (20A; circled/arrow) for
the VDP module in the Rear Power Distribution Box
(Z2a).

3. With the VDP disconnected, perform the same test from Step 1. If the call interference can no longer be heard by the
recipient, then the VDP is most likely the cause.

4. If the call interference is STILL present during the test call, then the VDP is NOT the cause, and you must continue with
standard diagnosis.

5. Reinstall fuse F224 (20A) for the VDP module in the rear power distribution box (Z2a).

Once the VDP module is determined to be the cause of the interference, the solution will be to re-route the
VDP ground point from Z10*8B to Z10*10B. The grounding cable is re-routed as follows:
1. Obtain the new ground wire repair kit (PN 61 12
5B838E2) for the VDP module.

2. Access connector A567*1B on the VDP and
remove pin 1 (1.5 BR). This pin and wire can be tied
back to the harness as it will not be used moving
forward.

3. Access ground point Z10*10B. Remove the
mounting nut and install the eyelet from the Ground
Wire Repair Kit. Reinstall the ground nut and torque
to the correct value.

4. Route and secure the new ground wire along the wiring harness to connector A567*1B at the VDP. Install the pin from the
new grounding cable into pin 1 of connector A567*1B.

Note: A part exchange will NOT remedy the issue and is not permitted. This is NOT a software issue, so
programming is not permitted. This topic is a hardware-related issue.
