Just what i found too.
Glow plug control unit fault.

If anyone is interested i have a iPhone app which searches OBD2 codes.
Just search app store for "OBD2 Codes"
Very handy indeed.
Also for anyone who wants to play iPhone / iPod Touch music through an aux connection and wants easy track control -
FordDashboard V1.2
Gives full screen play / pause / swipe for previous and next track, and track art - also ability to customise the background - has a nice ford logo as standard.

I get the same problems on my car. Not sure if its the same code but this is what happens. Seems to be when the air temp is colder. The error will go away when its warm. Im going to have the glow plug/s changed soon so hopefully this might sort it out.
