How much is a Synchmate? £120? And that's all it'll do. It you're serious about running a P38 then I'd seriously suggest researching the Nanocom or the Lynx diagnostics or similar tool. It is only a matter of time before you'll need it!
 
Popular fault with the P38.

The BECM looses sync with the engine ECU so the immobiliser can't be switched off.

Search for "BECM loss of sync" on here, covered many many many many times. You can buy a cheap(ish) tool to fix it called a syncmate. Small enough to keep in your glove compartment and will save you calling out assistance in the future.....but I'd get a Nanocom (a small Range Rover diagnostic computer) because it does other useful things like reading fault codes should you find yourself in the unlikely position of having another problem with your car!

Low battery volts does seem to be a causing factor. Winter is coming, buy a new one of these now!

New Battery now on order as per your reccomendation :)

Thanks for the reply - I am in Edlesborough - Bucks - which is near Leighton Buzzard.

I have just spoken to a Land Rover Specialist in Kings Langley who are coming to recover the car this afternoon and plug it into "T4". I will update in the next couple of days with a diagnosis if they can find one so that it can possibly help someone else.
