Just got home. Thought I'd check just in case it's fixed itself. No joy unfortunately. Tried disconnecting battery for 20 mins, no joy, and have also got a ' power window trapped' ( not exact phrase, similar) message as well and noticed the windows have stopped lowering slightly.
Seriously, how can a flat battery cause this much grief!!
( will see if Maks Bt scan tool will clear when arrives, that's he's kindly posting me)
