andrewmac Posted August 22, 2015 Share Posted August 22, 2015 Hi, I have a 2007 Focus 1.6 LX TDCi. Intermittently the Engine Systems Fault message comes up with the red LED and the car instantly loses power. Then at some point, sometimes 10 mins, sometimes a day. the light goes out and power is instantly restored - no gradual change, its like someone's thrown a switch. More recently the engine management system light has come on but its stays on all the time and when the red warning light is out the car drives perfectly, so presume the engine management problem is unrelated. Recently had to have the turbo changed so don't know if that's related to this problem. Is there a list somewhere of problems that bring up the 'Engine Systems Fault' message? Anyone got any idea what the fault could be? Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted August 22, 2015 Share Posted August 22, 2015 A fault code is needed to accurately diagnose the issue Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted September 1, 2015 Share Posted September 1, 2015 Agreed, a code reader is the best thing we can have at this time so we know wehich general area of the system is suffering. Quote Link to comment Share on other sites More sharing options...
