2012-3 Manual Regularly serviced, superb until one month out of warranty.Then out of the blue ""˜engine malfunction' light, lumpy tickover and intermittent starting probs. Local garage (v good) referred me to Ford Dealer. Bad experience but upshot unable to diagnose fault thought it could be valves but no guarantee (minimum £700). Had to live with it. No rectification. 18 months on and it's now sticking in gear after longish drives. Local garage checked all the obvious points. No explanation. Seen elsewhere that wiring harness might be problem. At wit's end. Obviously unsaleable as it stands. Help needed!
