Hi,
These symptoms seem very much like I've been experiencing with my D2 TD5.
The list of things replaced or checked over the past few months is quite extensive
Injector harness replaced,
Injector seals replaced,(three times)
FPR replaced,
Fuel filter assembly replaceed,
Fuel pump replaced.
The cylinder head was removed and pressure tested off of the engine and was found to be porous from one of the injector ports to an exhaust port, allowing exhaust gases to pressurise the fuel system.
The distance travelled between breakdowns varied from 800 miles to 300 yards.
The situation at the moment is that my local garage is trying to source a replacement head at a price much lower than land rover's £3188 plus VAT.
The only bright side to all this, according to one of my daughters, is that I've saved a fortune in diesel over the past few months.
Regards,
Alex
