There is no immediate repair required unless the BMW vehicle is currently experiencing this problem.
Customer Notification Letter
Even though this is NOT a Recall, BMW NA is sending VIN-specific customer notification letters.
Note: Causes items A, B, other seat CIS mat system-related components/seat heating, and/or other
SRS issues are excluded from this extended coverage.
CORRECTION
Front Passenger’s Seat Capacitive Interior Sensor (CIS) Mat
1. Consultation with the customer whether objects were possibly laid on the front passenger seat, or the seat was subjected
to moisture (e.g., from rain through an open window, wet clothes or towel, or the spilling of fluids on the seat cushion
surface).
2. Perform a non-invasive check for moisture/stains on the seat and at the CIS evaluation electronics module electrical
connector.
3. Check the seat CIS mat’s ground connection and re-secure it as necessary.
4. If there are no obvious moisture/stains, the next step is to check the vehicle’s installed seat heater/CIS mat sensor part
number and its revision index number against a corresponding matrix. The matrix will help you determine if the installation
of the seat CIS mat wiring repair kit is required to address an inadequate shielding condition with the seat occupancy CIS
mat’s connection wiring. See attached Procedure.
Note: Replacing the CIS electronics and / or
the ACSM module will not correct this issue.
PROCEDURE
See Attachment for procedure.
