Have the same problem with my 2012 plus 4, light comes on at various intervals, did a basic check, i.e plug color, exhaust emmisions, nothing obviously wrong so carried on driving, phoned my dealer, not another one was his reply, seems a dodgy batch of something could have been used, so would order and change under warranty, phoned to see which year Morgan would supply the part and was told , we have another one in with the same problem. I doubt Morgan could give a damm about after sales service or keeping a car on the road with a quick supply of parts. Still I am still mobile and enjoying the car.
