Did you ever manage to resolve this? Whatever it is is loose under my passenger seat and I am getting airbag sensor code 16 on the dash.

It actually looks like a plastic bracket has broken and everything i've read leads to the solution being purchase of a whole new calibrated passenger seat system - which will almost certainly be extortionate from a dealer.

Any suggestions for a repair or solution - I think it's an MOT fail, so I've just over a month to fix it.

The .pdf in post 2 was informative, but didn't really help.

Cheers,

Richard

Presume black fairly thin module?
Its a weight/proximity sensor tuned to your car. A one from a different car will prob not work.
Screws under front off seat.

It has 2 moulded plastic lugs on either side that screw on.
Best seen by removing seat. To fasten back on need to remove seat.
It may be possible to glue/heat weld back together. It's not a moving part but may be very sensitive to heat etc

Thanks for this question lol
Wondered what it was hanging loose under that seat. Giving no problems though so is getting left alone, might try some harry black maskers on it if ever need to put anything under the seat though.
HBM = Duct tape btw.

The airbag system will not fully function if it is sensing any faults so would strongly advise sorting.
Don't need to pull seat out of car.

Tilt angle of seat back plenty forward.
Undo battery and leave for bit so airbags disarm
Undo bolt and pull multi plug off
Undo the 6 bolts (rear hidden under plastic trim removed with screwdriver.
Then just tilt seat back inside of car and sort sensor.

And reverse when done.

"sort sensor" is easy for you to say :)

Does it just need to be stuck/screwed/fixed back where it came from, or is there more to it than that?

If its faulty, what do I need to buy and fit to sort it?

I've got the Haynes manual, and am quite handy with faults on a boat, so it shouldn't be beyond me to fix it.

Thanks for the input!

Doubt its in the manual.

Should just need fastening back in position.
Doubt you need to replace. Plus a new/2nd hand would need coding to the car.
When I replaced my seats I had to swop the sensor from old seat to cure light. Can't remember code it produced.
Lift the seat and will see the position it takes. Its plastic sensor to metal base so screw is best.

Once seat is up you will wonder why you hadn't done it already.
its 2screws and 7bolts to access. At worst put couple of washers on screws and bend the sides of washers to make a securing frame to hold it.

I suggest I had a similar issue as the front passenger Airbag light kept flickering, it turned out to a broken plastic lug on the Airbag weight sensor at the back of the seat, I eventually put in a washer to hold the sensor tightly in place. job done.. ....

In the event, my car went to the garage for a turbo and actuator refurb, and MOT, so I asked them if they could fix the sensor, and they did. It definitely didnt add much to the bill so looks like it was as simple as you suggest.

I couldnt DIY as I had a gall stone attack, and gall bladder out mid April - didnt see that coming !
