The ignition (and most dashboard) lights come on, even when the car is switched off, key is out and the car is locked. This, of course, flattens the battery.
It happens approx 30-60 seconds after the car is switched off. Nothing else works when this happens i.e. wipers, indicators, electric windows etc
I currently just disconnect the battery when I park,but this is a bit of a pain. Any ideas??
