Fiesta 1.6 TDI fault light but no DTC

Afternoon Everyone,

New to the forum, and looking for some advice and/or guidance. I own a 2006 Ford Fiesta 1.6 TDCI and the warning light (the one shaped like a cog) comes on and the car goes into limp mode and tells me to check the manual. 

I have Run a diagnostic check with a cunsumer level diagnostic tool and no codes are available. Starts again fine, no smoke or noise that would indicate there is an issue and no warning light. All fluids are at the correct levels and the car is regularly serviced. 

Lots of similar topics say it could be the EGR valve, but it's not idling badly and I would assume it would put up a code. I was thinking it could be the radiator; the warning light comes mainly when engine is at Temperature and I'm in slow moving or stationary traffic. I've got the car to temp and turned on the A/C but the radiator fan doesn't come on. Could this be the issue and the engine is 'protecting' itself from overheating?

Any one experienced this sort of issue, and can help me resolved this. Your advice will be greatly appreciated.

Thanks in advance.
