Anyone else had anything like this?
Had the 300c washed at a carwash, When I got in to drive home there was a chime and the RED airbag light in the instrument cluster was on (lower right) and the Orange "passenger airbag off" indicator was illuminated (Center cluster).
When I got home I read the manual and it said this indicated an Airbag system fault, bring it to a dealer (I will). BUT, I experimented a little.
With engine running I sat in the passenger seat, both lights went off.
When I sat back in drivers seat they came back on.
I tunrned off the car awhile, got back in passenger seat, moved it back/forth, up/down and bounced in it a little.
Started the car again from drivers seat as normal and the Airbag fault lights no longer come on and stay on. I pushed down on the passenger seat with my palm and the "passenger airbag off" indicator illuminated as it should, when I released the pressure it went off.
I know they normally come on when starting the car and go off after about 5 seconds, but my problem was they then stayed on AND there was a chime that chimed twice.
