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
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).
Perform a non-invasive check for moisture/stains on the seat and at the CIS evaluation electronics module
electrical connector.
Check the seat CIS mat’s ground connection and re-secure it as necessary.
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.

Note: Replacing the CIS electronics and / or
the ACSM module will not correct this issue.

PROCEDURE
Note: Before performing this seat heating wiring repair kit retrofit/installation procedure and submitting
a claim, first confirm that the vehicle has one of the above coverage notices in the Warranty Vehicle
Inquiry’s (WVI) Vehicle Comments section.
Also review the Repair History (Claims) section below in the WVI to confirm that a prior claim for this
wiring repair kit retrofit/installation procedure has not already been submitted and accepted. This would
include Repair Code 52 10 90 01 00 claim submissions.
Use AIR to identity the vehicle’s installed seat option, and to determine if there are also any optional seat
accessories installed, this information is required other steps later in the procedure.
