Hi, I'm after some help... my sport 197 has just failed its mot due to the drivers seat not moving. The garage said I will need a new seat base as they will need to cut through the retaining bolt holding the seat base down. I assumed it was just the runners I'd need but apparently the garage are saying it's the mechanism not functioning. The base is apparently £1500 from Renault!! Or the runners are £262,Has anybody else had this problem? As I've never heard of the seat base being faulty?
