My C-MAX, 11 Reg, 21,000 miles has gone into Limp Mode on a number of occasions. It is in warranty and serviced by Ford Agents since new. The local agent has diagnosed a fuel filter fault replacement at a cost of £140 including £80 for using their electronic diagnostic system and not covered by warranty. Forums show this as a common fault. The £80 charge is excessive!

Surely electronic diagnostic equipment is a necessity with complex modern vehicles and should be part of their tool-kit. They will be charging extra for the use of their spanners next!
