Hi, I have 05 plate mondeo tdci. I was driving on motorways glow plug light came on flashing and engine cut off. Started again it was on but again the same problem. Also notice loss of power on engine. Took to the local ford garage. They did a diagnostic check and advised to change fuel filter and Cam shaft sensor. Had done it somwhere else as ford's labour charge is too expensive. But yet again it's making me same problem. Took to the ford again made complain. They had another check and have been told they cleared the codes so it should be ok. But after i took the car from the garage it's making again the same problem. Glow plug flashing and engine light is also coming on and loss of power on engine and cutting off totally. Also it takes a time to start on engine in mornings. PLEASE HELP! i have no idea what it might be
thanks
