If the car is running OK take it to another garage - a more reputable one - and get them to reset the ECU.
May have to be a main dealer or if you have a decent service manual you could do it yourself.
I'm not familiar with Fords but I've done a reset before on Vauxhalls and Volvos.
If the light comes back on, then you perhaps have a genuine fault.
there is an issue with the dci engine as fitted to the mondeo but this does present with a misfire. if the engine is running and starting fine then its probably an engine management software problem. no other way around it than find someone who knows and is'nt just guessing. i agree with billy, even if you have the pump changed it's the ecu that's putting the warning lamp on.rip off entirely possible.
