Enjoyed reading this thread, to an extent... motoring can be annoying, frustrating and everything inbetween! I've had the same issue with my Mk4 ST edition, battery completely going flat, car deadlocking itself and had to have it charged up etc... interesting to see this though. Curious if the little pesky door light is the issue! Might have to give that a try myself...
One issue at a time though... currently battling with a stiff/sticky/dry feel in the brake pedal accompanied with a "pssssh" when pressed. 71 plate, 13k miles.
