Hi, having a passenger airbag fault on dash. 

find the airbag fault but won't clear, come back straight away, B102004 "Key switch for airbag - off, passenger faulty."

Fault show up after i removed the glove box, have check yellow connection, its on.

Any idea ? Thanks.

Usually this is caused by a loose wire under the passenger seat 

Thanks, will have a look tomorrow 

 

Please keep us posted on how you get on 

Had a look under passenger seat, everything look connected. 
I remove the glove box to fit car play, only thing i disconnect was the light from glove box. Airbag yellow plug was still in. 

Hi there,

I had this issue on an A3 some years ago, had the underside of the seat wiring replaced and that didn't cure it.

In the end the issue was the clock spring in the steering wheel that needed cleaning.

Hope that helps 👍

Thanks for that, did replace the steering wheel few weeks ago, everything was fine until i remove the glove box yesterday 

Ok, disconnected the battery, remove glove box, disconnected airbag, but everything back, clear the fault, and so far so good, all good. 
dead battery probably doesn't help. Car under warranty so waiting for new battery to turn up.
