My dash is also lighting up with the seat-belt and airbag light on constantly. As per usual the seat occupancy sensor mat is suspected, I took a look under my seat and found the following loose plug (see image).

Is this the plug for my seat occupancy sensor ?

If so: Where do I plug it back in ?

If not: What on earth is it for ??
No, I doubt it. I belive this connector is there for extra features your car does not have. I belive this connector is for the subwoofer that goes under the seat if you are equipped with L7 sound.

I also had the same airbag error. This issue with Mat sensor has been going on for a long time and is up to the dealership to replace it especially if you are not under warranty.

Not sure if my dealership replaced mine due to a recall of since I was still covered by warranty. I cannot remember i was like 4 or 5 yrs ago.
