Haha, ok, glad to hear it's not just mine that's draining the batter for no reason! I don't make it a habit not to lock the car, but my wife seems to forget

Aye, I have to lock mine...doesn't like being left unlocked as it won't go to sleep, it's always searching for an input from the keyfob.

It's strange for me to lock cars...or anything for that matter living up here in the north sea.

Hi,

Does anyone else's Discovery 5 drain the battery if the car is left unlocked overnight? If i do this, in the morning I will get a low battery warning on the dash and need to start the engine to charge the battery back up. I'm wondering if this is "normal" or not.

Thanks,
Ankur
