A quick update. The service and MOT has been done, fault codes were read - only fault code referred to the O/S unit. Apparently Morgan say to delete the code and re-calibrate the O/S unit - which has been done. Has it been fixed? Time will tell!
MOT failed on a defective hand brake...I was charged to adjust it! In the old days adjustment of the hand brake was part of the service! Unfortunately I can't find a service schedule for the plus four so I don't know what it includes. Does anyone have something that lists the service items? The hand book really does not help.
