Dreaded Ford Focus TDCI starting issues

[bazzer107]

I'm new to the forum, so be gentle with me

I have a Ford Focus 1.8 TDCI Duratorque and I have had starting issues with, let me explain;
When ever we have had a cold spell the car would start and run for 10-15 seconds then cut out, after trying to start for 1-2 mins it would start and run without any issues.

Forward onto the next cold spell and we would have the same issue again. I have checked the DTC (Diagnostic Trouble Code) which has logged no faults! I have replaced the cam position sensor which is a know fault on these diesels as well.

I have noticed that there is a ticking/whining noise coming the engine bay even when the engine has not started but the ignition has been switched on and it stops 10+ seconds after the ignition has been switched off or when I remove the connector plug from it. The part where the noise is coming from is in the picture added below behind the oil filler cap.





Could this part cause the issue I am getting with poor/bad starting?
