    Easy all,I'm flying back to the UK from Qatar next week, for 8weeks, I'm disconnecting the battery as temps here hit 50oc which tends to screw the battery over. Can I reattach the battery when I get back and code it with Cody?.....i left my battery in last year and it was foobarrd when I returned, can do without the hassle seen as I bought the car without even telling her indoors!:muttley:.
    Cheers.

    Just disconnect the negative terminal. No need at all to code it.

    Make sure you have your physical key to open the car again though

    the lci model doesn't have a key lock on trunk
    how will you open the trunk to get to the battery ?
    the lock is operated by a switch

    Good point about the Lci model not having a locking barrel on the trunk.

    For Lci You can open the door, flip the bonnet and connect power to the charging terminals.
