I have a 2001 406 3L coupe, and recently, every now and then, the airbag light on the dashboard will come on (flashing) and stay on until I turn off the engine. Usually it's ok for most of the next trip, then eventually it starts flashing again. I presume it is a dodgy connection, not an airbag that sometimes works and sometimes doesn't, is there an obvious place to look for a connector etc? Thanks, Pascal.
