Passenger Seat Sensor Mat Replacement

[golf4dj]

2008 x5 3.0si (120K miles - cold weather package with heated seats)

A couple months ago I got the dreaded Passenger Restraint System warning which would intermittently come on and then go off when someone is sitting in the passenger seat. Unfortunately, over time the warning would come on more frequently to the point that it is on full time now regardless as to whether someone is sitting in the seat or not.

Pulled the code using the BMW iCarly App which revealed code 93C3 which is a defective passenger seat sensor. I realize that the sensor is subject to a recall, unfortunately mine is not covered.

Fast forward - a few weeks ago I ordered the replacement part as identified by RealOEM (Part No. 65779171319 from ECS Tuning). Today I took the seat out and tore it down to get to the seat sensor (pretty straight forward does take some time).

To my surprise the existing seat sensor looks nothing like the new one I bought (electrical connections are not quite the same either). The part number from the existing sensor is 65779192246 and does not appear in the RealOEM catalog.

The first pic shows the original sensor which has a black cover, the second pic is the close up of the original part number and the third is the new sensor I ordered.

Anyone have any ideas - I am at a total loss.

Thanks in advance - DJ

BTW - I did post a similar question on another board.
