Yes everything works fine locks, lights, tape etc the engine just does not turn over and the battery is fully charged. I have had the car up and turned the engine manualy and it turs freely.

Do you by any chance have a multimeter?!

If so, get it on the smaller starter wire going to the starter, not the big fat one, the little one which actuates it.

Then get someone to turn the key for you, see if you have 12volts to the motor...

gota start with the basics! the engine code/malfunction message maybe a red herring.

So you have 12volts to the starter when you turn the key...but the starter doesn't turn?!

Erm...starter motor!

Little off topic maybe, but a 57 plate would be a mark 6.5?

If thats the case why would it say high tempreture on the display?

how do you know for sure that the battery is fully charged? you could try disconnecting the battery for half an hour just to reset everything.

As I said, maybe a red herring...it maybe that the sensor is misreading.

However, basic electronics, a starter motor has a 12v feed (big fat wire) and an actuator wire (smaller wire) to get the big relay to switch the power to the motor and turn the engine.

If you got 12v on both wires when you turn the key to start the engine but the motor dont turn...well it gotta be the motor!!!

Try giving the motor relay a bit of a wack with a mallet or hammer and piece of wood while someone is turning the key to start...maybe a sticky starter relay.

Has to be that...worry about some stupid temp sensor and dumb ECU later!! :lol:

Take it back to the dealer, surely you're within warranty? Or am I being dense? If so I apologise...

I gave that a try but had no luck so gave the car a good push in second but still no luck. I think it is going to be some kind of sensor. Will have a good sniff around tommorow.

If you got 12volts constant on the big fat wire, and 12volts on the actuator wire when you turn the key to its 3rd 'start engine' position, it has to start with the motor...try giving the motor 12volts via a wire from battery with engine in NEUTRAL obviously, see if she spins then :)

You gota ensure the basics and work out from there :)
