My 02 plate diesel focus has started giving me problems sometimes just after starting, sometimes whilst driving along, the glow plug light starts to flash, and the engine note changes / sounds like its not running on all four and usually ends up cutting out. 9 times out of 10 it will restart straight away other times can take 5 or 6 tries then fires. Any ideas what it could be????

 

sounds like possibly an egr fault although i never heard of it on a focus?
is it a tdci or tddi?

 

its tdci thought it might be an injector fault?

 

I'm sure on that age they use the light in conjunction with fault reporting, so get codes read.

cam sensor common on focus's with those symptoms,depends what colour the sensor is as they modified them.black sensor is old type,grey sensor is new type.best to have codes read
