aidmcn Posted May 12, 2011 Share Posted May 12, 2011 Hi i have a 2005 focus 1.8 tdci which has had an ongoing problem that manefests itself when driving along, the display reads reduced power, followed by power assist failure and ultimately when it stops the message is engine systems fault. At this stage the engine immobiliser light is flashing quickly and the car will not turn over or start. To date the ford dealer has tried the following on the five occasions that it has been towed to the dealership. Reprogramming Keys Replacing the internal fuse box Replacing the battery Soldering some cables he states were loose behind the dash and finally replacing the instrument cluster Does anybody have any knowledge of a similar fault and how to resolve it?

Leemaxd Posted May 13, 2011 Share Posted May 13, 2011 Sounds like to me something to do with the alarm/immobiliser. Quote Link to comment Share on other sites More sharing options...
