Airbag Light Intermittent
I have a US LR3 and the airbag light is going on due to the left driver door sensor. I have tried changing the sensor, the steering clock spring, and checking the door wiring harness and I don't see any issue. However the light still comes on intermittently and usually just shutting down and restarting the car will make it go away. I also get codes for a ride height sensor and loss of communication with instrument cluster. The battery is new and I have tried clearing the code many times but it still comes back. Are there any ideas on how to find the issue?

hi
B0091 Left side restraints sensor 1
check the connector block under the seat is tight , think the small bolt is 7mm
make sure u don’t pull the connector block apart whilst the battery is connected , yellow wire is the seats airbag system, if u wish to separate that connector block, disconnect the battery then wait 30 x mins
