Had MOT back in December by Indi and airbag light was advisory. I am told it's the occupancy sensor but when a passenger gets in and does not put on seatbelt the warning chime sounds. Does this mean the occupancy sensor is working as it has recognised a passenger? If so what does the code G3F9 that was printed on the service breakdown sheet mean?
Ps I also have a annoying rattle/squeak coming from the dashboard......anybody else have similar they can help point to a cause or solution.
