Get them to check the wiring loom and the various electrical connectors. My 1.8TDCi started cutting out two weeks out of warranty, with an 'engine system fault' but no enging management light lit.

The dealer first changed the crankcase sensor but the car cut out on the way home from the dealers! They had no idea what was causing the problem until a Ford tech told them to check the wiring loom. Just checking the loom and connectors fixed the problem, so it was likely a dodgy connector somewhere.

In my experience garages have no idea when it comes to diagnosing faults like these. They rely too much on the computer and have a tendency to heap huge costs onto the customer by not taking the time to diagnose the root cause, instead fitting a series of expensive parts to unsuccessfully attempt to fix the symptoms.
