Thanks Del!..I don't believe that i have any one corner that drops vs another but will do some more checking over the coming week.
That said, i got in the car this morning and did a quick test on the battery again with VCDS before turning the ignition on...12.1V and when i started her, it was so much better than with the old battery.
I am hoping that i may be lucky and it was the battery that was due to be replaced. That said, i'm going to keep an eye out on any further drains, particularly after a few more days of sitting idle.
Thanks,
Oli
