Hi... 02 C5 2.0 diesel estate When the engine is off, there is a constant clicking sound, perhaps a relay? located in the rear cargo bay on the right hand side (driver's side). Any ideas? Thanks from Dublin

2002 C5 2 litre tubo estate. An attachment point for the driver seat is broken or undone. It is on the front right, beneath the seat, a curved metal arm, aft of the plastic tray, now hanging down. Dublin dealer wants €952 to repair. Any ideas or suggestions? GREAT CAR by the way!
