I have a 2005 ST TDci with the 2.2 diesel engine. The glow plug warning light has started flashing and the car goes into limp mode. If i turn thr engine off and back on again it runs fine for a while then does it again (usually when warm). I have had the car read and I'm told its the ECU that controls the turbo. You are talking mega money to fix this I'm told and I have a had time believing its such an expensive fault when the car still runs as sweet as anything.
Wonder if anyone else had this problem and open to any suggestions for further investigation. The car has done 51k and passed its mot last saturday including the emissions obviously.
