Important Production-Date Information

Although BMW parts catalogs broadly associate 65776927500 with the 2000–2006 E53 X5, BMW's component diagrams show an important production-date distinction.

For E53 applications, 65776927500 is shown for vehicles produced from approximately 07/2003 onward, while earlier vehicles may use a different seat-occupancy electronics module, including 65776940191.

For this reason, customers with a 2000–2003 X5 should not purchase based solely on model year.

Always verify the original module number and vehicle production date before ordering.

Important: Control Module vs. Sensor Mat

This listing is for the seat occupancy electronic control module.

It should not be confused with the passenger-seat occupancy sensor mat.

BMW catalogs identify the related E53 passenger-seat sensor mat separately as:

Sensor Mat Part Number: 65776921952

The control module and sensor mat work as components of the seat-occupancy/SRS system but are separate parts.

What the Seat Occupancy System Does

The passenger-seat occupancy system detects whether the front passenger seat is occupied and provides information to the vehicle's restraint electronics. This information is used as part of the vehicle's passenger airbag and seat-belt monitoring strategy.

A malfunction in the seat occupancy system may be associated with symptoms such as:

• Airbag/SRS warning light

• Passenger restraint system warning

• Incorrect passenger-seat occupancy detection

• Seat-belt warning operating incorrectly

• Occupancy-related diagnostic fault codes

These symptoms can also be caused by the sensor mat, wiring, connectors or other SRS components, so proper diagnosis is recommended before replacing the module.

Additional BMW Applications

BMW parts catalogs also associate 65776927500 with certain other BMW models, including:

• 2003–2005 BMW Z4 2.5i / 3.0i — E85

• 2004–2005 BMW 645Ci — E63/E64

• 2006–2007 BMW 650i — E63/E64

• 2006–2010 BMW M6 — E63

Fitment outside the X5 E53 should always be confirmed using the VIN and original part number.

Before Ordering

Please compare the following with the original component:

• BMW OE number 65776927500

• Connector configuration

• Module housing

• Mounting arrangement

• Vehicle production date

• VIN/application

• Existing diagnostic fault codes

Because this component is part of the vehicle's Supplemental Restraint System, professional diagnosis and installation are strongly recommended. Coding, initialization, calibration or fault-code clearing may be required depending on the vehicle and repair performed.
