focus 1.8TDCi DTC code P2339
Has anyone seen this fault or could offer some help?
Car was flying down the motorway until I slowed down to turn on to a side road. The glow plug light started to flash and car went in to limp mode. Managed to get to a friends house where I parked up for the night. Tried to start the next day, light still flashing with just the ignition on. Took a while to start, lots of white smoke and sod all power. Managed to limp to a garage (white smoke stopped once driving) and had fault code P2339 diagnosed. Told it was cylinder 4 fault but trying to get head around fault being present when engine not running...! Have replace knock sensor but fault still wont clear. Various things on web saying it could be all sorts of issues from cam sensor to crank sensor. Injectors may need recoding but dont believe it is the injectors as they were all replaced last year. I have also replaced fuel filter and checked for debris. Gut feeling is electrical but I am no mechanic so any help would be welcome!!
Many thanks
