Well for the first time in years an actual fault on one of my cars.

Under moderate to hard acceleration engine drops into limited operation and the Spanner Icon comes on. Fault clears after ignition off until next time.

Got it looked at, no really significant fault codes, some old ones, no new ones. Dealer though it might be dodgy diesel as relatively new fuel filter was 'waxy'. New filter fitted, PCM updated, and additive added, but still the same. 

Story continues next week......................................

Please, no 'Spanner' jokes.

I had a similar problem a few months ago where the power was lost suddenly when when accelerating hard and the spanner Icon appeared! It only happened occasionally and Ford replaced a Oil Pressure Solenoid which had shown faulty. I've had no problems since!

Thats interesting. When he was doing the fuel filter he mentioned they had seen a few of the oil pressure pump solenoids fail. 

That could be the next step

i’ve just looked it up. £100 ‘ish. Good job it’s under warranty. 

Similar scenario to the issue I had with my Kuga. This turned out to be a sensor on the DPF. The filter itself was fine, just a dodgy sensor. 

Same as @Edge of Reason, my old Kuga had the same symptoms, but my DPF injector was blocked and so it couldn't do a regen. Not had the issue on the Edge though!
