Sound advice from Tdci-Peter on the Ford Owners Forum,

however in my experience I always felt like there wasn't a problem with the mechanics and the workings of the injectors, it was more like communication between the sensors and the injectors - after cutting to limp mode, and restarting the engine, the car would drive for 500 yards sometimes, other times it would drive for 500 miles before cutting to limp mode again.
Before cutting to limp mode, the engine would stutter, as if there was an air lock in the system, or the sensors were not fueling the injectors correctly. There was no pattern to when the malfunction would occur, we've had it in slow moving traffic, from start up, after long distance driving, etc. but more often it would be in the summer months with warmer air temps, on the motorway, accelerating from 4th to 5th, on an incline.
The AA and RAC recovery technicians have always questioned the electronics and circuitry because the mechanics of the running engine look and sound good.
Ford workshop have always insisted on replacing the injectors based on their diagnostics.
If this was a fault due to wear / age I think i'd be able to accept being out of pocket by £3k, but this is from an inherent problem from when car was manufactured.
We bought the car from a Ford dealer, with a full history in the service book.
At no point have Ford customer care / Ford dealer / Ford workshop told us about the faulty injector batch, or suggested we have all four replaced at the same time, which would have made more sense financially, and mechanically for the engine running efficiency.
