Battery drain Quiescent current problem

[Shaf1926]

So, I'm sure others have had issues but Ive not yet found any threads which have helped.

I have a 2006 Allroad
It was having various issues and fitted a new, correct spec Varta battery earlier this which seemed to resolve most of the issues.
Recently, the battery is draining ridiculously quickly. I can put it on charge with a good smart charger. After being fully charged, Starting the engine if fine. After 12 hours, the battery doesn't have enough charge to start the engine any more.

In VCDS have amongst other things fault codes for Quiescent current stages 1 through to 6.

A bit more info.
I've noticed that at night the dashboard turns itself on, fully lit up. Whilst the car is locked.
It's very strange because the lights are in the fully off position. So even if the car were yo wake up the dash shouldn't be lit.
When I unlock the car the dash turns off.
Has anyone else had similar?
