A couple of months back, less than a month after the warranty expired, the airbag light came on and refused to go off. Manual says issue with either airbag system or seatbelt pretensioners. Took car to dealer, they could not find the fault but cleared the light anyway. They reckoned it was triggered on by an object [rolling] under the seat(s) and advised that should the light come on again the car would require a new airbag unit @ c. £1,200. On the same day, as I was parking the car on the driveway at home, some 7 miles from the garage, the light briefly came on and disappeared. Did so on
