I have recently bought a 2005 Ford Focus TDCi 1.8. In the first week it developed a fault with a loss of power and the 'Engine System Fault' warning light came on. The dealer fitted a new fuel filter but it lasted less than 24 hours before breaking down again with the same problem, except that this time the engine cut out completely and I couldn't restart it and had to be towed home. A local garage eventually managed to start the engine after priming it using a hand pump, there were no error codes retained when he ran diagnostics. The car then ran for six weeks, but I broke down again with the same fault. This time my recovery guy managed to start the car by turning it over and giving the throttle plenty! Again, no error codes. Any ideas anyone?
