Wierd Electrical Fault (Time Clock)

Hi all,

I have a wierd electrical problem on the car.

Got in the car yesterday and the time was wrong, reset it and carried on as normal. Got back in the car this morning and it was wrong again. Reset it (again) and then went in to work.

Wrong again when i left work so i reset it for a third time, went in the house and then went back out to check it. Caught it doing this so video'd it, very strange. It stopped as soon as i turned the key in the ignition.

I've scanned with VCDS and there was a low voltage fault (which reset and hasn't come back) but that was it. Anybody have any idea what the problem could be?

Cheers

Phil
