    I must insist for the last time to measure the battery voltage WHILE CRANKING, the fact that the battery is new is irrelevant if there is a draw while cranking for some reason and the voltage drops more than 2V it will not start

    Yes, after the orings were changed it's a good practice to check the oil level and smell in the first days after each drive

    You are not supposed to push the throttle once it fired up untill it didnt idle a bit on it's own and if it started once and ran no matter how never touch the throttle without engine already running cos you flood the engine, insisting to start it...

    "OEM" means nothing these days, it's just a marketing scam for various aftermarket parts, if you can't afford genuine LR(which are actually green) then buy branded ones like Viton, a friend of mine fitted some so called OEMs and they leaked...

    Just seen this it must get above 250 rpm to start, see the battery voltage while cranking, if it drops below 10.5V it will hardly start cos it needs more to open the injectors it's in the "Outputs" menu last line... better read the user guides...

    Yes it can cos once you started it and removed the jump leads the battery voltage can drop below 10V which mixes up the ECU, injectors and sensor readings, the more the voltage drops the worst the engine will run untill it stops not working how...

    No it won't, the fuel cooler gets flow direcly from the bottom of the radiator, the return from the matrix goes into a T piece at the end of the cooler where it meets the outlet flow of the cooler when the thermostat in that piece is open cos...

    If the gauge went above normal means it was too hot already cos it leaves the middle at 120*C and the electric fan kicks in at 110 by default, so if it ran full time means there was more than 110*C and that will kill the engine on a long run...

    The matrix has permannent coolant flow and the heating/cooling is managed by the servomotors which are opening/closing the flaps, when cooling is set the flaps for the heater core are supposed to be closed and all the air should go through the...

    Then read the code with nanocom or hawkeye(i dont know other tools to be 100% reliable with the Td5 engine management) but as long as the EML comes on it can be only the crank sensor or TPS unless the ECU is at fault.
