SITUATION
The customer complains that the Airbag Warning Lamp (AWL) is illuminated, together with the Passenger Airbag Status Lamp (POL). The problem may be intermittent.

Depending on the vehicle concerned, one of the following OC3 seat mat faults is stored in the SRS Control Module/Satellite - 95B8, 71, 93C3, 97E0.

[NEW] In the interest of customer satisfaction, the first performance of the repair procedure listed below, to correct this specific airbag warning lamp issue on eligible affected vehicles, is covered for 10 years without mileage limit.

[NEW] The attached letter has been sent to the owners of all affected vehicles, as described in item "A" below, to advise them of this change.

[NEW] All subsequent repairs, as described in this bulletin, are then covered either by:

1. [NEW] The remaining time of the BMW Original Parts Warranty as applicable (refer to KSD2 for the defect code and labor operations); or

2. [NEW] The remaining time of the extended coverage period (for repairs beyond the parts warranty coverage period, submit as outlined below).

Affected (Eligible) and Non-Affected Vehicles

A. Affected vehicles: BMW vehicles which did not have an updated OC3 seat mat installed prior to release of the repair procedure in this Service Information bulletin.

Eligible vehicles will be shown in the DCS Warranty Vehicle Inquiry (see attachment).

B. Non-affected vehicles: BMW vehicles which already had the updated OC3 seat mat installed prior to release of this Service Information bulletin.

If a seat mat repair is required, this warranty extension does not apply to these vehicles.

Note that: on E65 and E66 vehicles, the OC3 mat was introduced from 03/2004. Earlier vehicles had an SBE seat occupancy detection system.

However, letters were mistakenly sent to owners of all vehicles up to 11/2005. Therefore BMW will honor this extended warranty for seat mat defects on the passenger SBE mat.

CAUSE
Microcracks in the OC3 seat mat.

CORRECTION
^ Follow the ISTA (Integrated Technical Service Application) test plan.

^ If no other faults are found, replace the OC3 seat mat.

Note that replacement parts for some vehicles are supplied without the cover material (foam pad with integrated OC3 mat). In this case, remove the cover from the faulty seat and reinstall on the replacement part per ISTA Repair Instructions REP 52 13 400.

NOTE:
To avoid the possibility of a preload condition on the assembled part, be sure to follow the repair instructions. The OC3 mat will not enable if there is preload.

For E65 and E66 with the SBE mat, refer to ISTA Repair Instructions REP 65 77 598 to replace the SBE seat mat. No programming is required.
