Hi foss just a quicky if you are lacking a bit of power send your ecu back to gary for a remap, had mine done by gary about a year ago it was a great investment. Now thinking of having stage two done.

These symptoms sound exactly like mine. It would start, miss at about 3.5 rev upwards and occasionally a minute after starting would stop and refuse to start if there was 1/4 tank or less of diesel. It turned out to be fuel pump, after new one fitted it drove like a different car, best thing I've ever fitted to my disco. Land Rover know they have a problem with the fuel pumps, I went through 1 pattern one and another 2 genuine LR ones.

Great that you fixed your Disco but the thread has been dead for nearly 2 years.
