This has finally I think clome to and happy ending, I have picked my freel 2 up tonight and all seems well, after a little over a month in surgery she is home.
After three software upgrades, a Turbo, Crankshaft Sensor, Engine Harness Power Train Controller as Ford call it or an Engine ECU as LR call it, I have it back safe and well and the fault was none of thr items mentioned it the list.
Solved by the Dealers own technician Bow down who went out on a limb as I think LR had just about given up, he thought about it logically as they all felt that the fault was with the sensors, he changed the Reluckter Ring (Excuse spelling or even the name) it is the ring located on the main crankshaft pulley which makes its own charge to tell the Crank Sensor what to do, apparantly it is has microsopic wires in it and it seems that this was the fault.

Am I glad that's over.

Doesn't have "microscopic wires" in it. Laughing Laughing Laughing
The "reluckter ring" as you've said it, is a ring shaped piece that has attached to it a magnetic band with an exact number of magnetic poles, minus one pole/gap. This gap is used by the ECM (Engine Control Module) as a reference for the crankshaft position.
The crankshaft position sensor is a pulse generator which scans the target ring/wheel and uses the Hall effect principle to read the magnetic stripe.
I am surprised that they didn't find this problem sooner because the lack of or a faulty crankshaft sensor signal leads to engine stall and compulsory stores a P0336 error in the ECM module.
A simple read of the ECM trouble codes (and of course a proper interpretation Laughing ) will lead you directly to the cause.

Hey alex, i can only say what they said Laughing I expected either yourself, Lar or Roverland to understand this more, it seems that if it was the sensor it would throw up a code but because of it being the ring it fails to give a code.
Any way I'm sorted, I'm happy Thumbs Up

I have actually warmed to the dealer a bit as they it seems on problems like this are not allowed to think for themselves but take on what LR say as it is warranty etc, they cannot fit anything without approval from LR, so the say that the dealership was not so clever is a little harsh I feel. Thumbs Up

Not quite...
Those two are working together. Either the sensor or the ring, the result is the same: missing impulses on the sensor output => engine halted and error code stored.
The ECM constantly monitors the time between impulses and if the difference between the last two impulses is greater than the previous ones, minus a reasonable amount given by the normal variation of the engine RPM, it automatically stops the engine and throws the error code.
This sensor/ring pair is one of the most important for proper engine functioning, because without their/its information, the ECM doesn't know the position of the crank and therefore, when to inject the fuel.
A proper workshop practice requires to change both: first the sensor and then, if no result, the ring.
