Original BMW Passenger Airbag Seat Sensor Mat for BMW 3 Series, M3, and X5 (1999–2006)

In the 1999–2006 BMW 3 Series, M3, and X5, the Original BMW passenger airbag sensor mat, part 65-77-6-921-952, detects whether someone is sitting in the front passenger seat so the airbag system knows a passenger is present. BMW builds the mat from SBR, a synthetic rubber, and it weighs only 36 g (1.27 oz). It is sold individually as one mat and is made in Luxembourg.

Original BMW Parts carry a 24-month parts warranty.

BMW introduced 65-77-6-921-952 in May 2002 to replace 65-77-8-099-028 and rates the change as exchangeable retrospectively, so cars built with the earlier mat take this one. Two more numbers, 72-10-8-235-912 and 72-10-8-099-028, also cross-reference to it. BMW applies the mat to the M52 engine in the 323i, 323Ci, 328i, and 328Ci, and to the M54 or M56 in the 325 models. It also covers the M54 in the 330 models, the S54 in the M3, and the M54, M62, and N62 in the E53 X5. One mat serves every engine in this fitment.

Common Questions

What happens if the passenger seat sensor mat fails?
The passenger side airbag will not go off if this sensor fails.

Where does the mat sit, and is it used in the driver's seat?
It sits underneath the seat fabric on the passenger side. BMW specifies it for the front passenger airbag only, so it is not a driver's seat part.
