M sport seat part number for occupancy sensor?

[Ilogik]

Hi I think my sensor has gone tits up on my m sport seats since getting wet, its throwing up an airbag sensor light. When I start the car and pull away it starts to beep at me even though there's nobody in the seat.

When my wife is in the seat, the car doesn't beep so I'm 100% certain that's gotta be the issue.

What other seat sensors could be causing me issues if its not these.

I've looked on real OEM but can't seem to see the part numbers.

Hi,
Browse realoem with your VIN as pre and post facelifts have different occupancy sensor mats. They are located under Audio, navigation, electronic systems / Electr. compon. seat occupancy detection.

However, before rushing into changing the sensor mat, I’d read codes and inspect the sensor status with INPA or ISTA, then check the connectors and wiring, espec. those behind the seat cushion. Also, an easy test to narrow the search would be to take a test drive with a buckled safety belt only.

Ahh that’s why I couldn’t find the bugger. I’ve tried buckling seat and it still beeps at me. Only time it doesn’t beep is when wife’s in the seat

What code reader would you recommend for reading the airbag codes

Cheap OBD cable and INPA or ISTA for me, but other options were discussed previously here: https://z4-forum.com/forum/viewtopic.php?t=131244
