Tested mine with VCDS. In the same state (everything off) mine was drawing 7.2A. However, before it went totally to sleep, it drew 8.2A for about a minute twice.
What is your Qv value? It's in block 3. My old battery was showing as 55Ah. My new battery is 0Ah.

Update time.
I did the long drive Friday night, engine was running for about 3.5 hours and I got to Hertfordshire at 9.30pm. Car was fine the following morning when I drove from Stevenage to Watford and back again, then did a run to the council dump Saturday evening. The car has been parked up since 5.30pm Saturday, and this evening the battery has returned to the same low state and the door LEDs are currently not flashing. Debating wether to put the charger on it again for a few hours, that will be all it gets here as the car is right by a main road.

Well I decided to stick the charger on it for as long as I can this evening, measured the voltage with a DMM and it was sitting at 12.26V.
Car started fine as I needed to to reverse it onto the driveway, there she sits now with an umbilical cord (life support almost) on the charger without power again. Any way to test how damaged the battery now is after 3 weeks of being run this low, I guess a visit to the local Halfords to determine the battery state maybe in order unless I can find someone locally to Stevenage who can be trusted. I am wondering this is something thats just been building up as she has always had an unidentified drain issue. When the battery was new it would go from 100% on the meter to 40% in about 5 days, however because the car is used daily its never really been an issue.

Manny have you ever replaced the Battery Management module? They can fail often with similar results to what you seem to be experiencing ?

Nope, not replaced that Neil, still the cars original one from what I can tell based on its very early firmware version.

Have you read the Qv (battery ageing) value yet?

I'll do that this morning,
Despite being on the charger until 11pm last night at which point I reconnected the car, the battery was at 11.7V this morning. Car still started ok though, but I had to use the key in the ignition, and after a 1/2 hour drive this morning it was at 12.31V but with the DMM connected you can see the voltage dropping. Current battery is a 95ah Varta blue top and 20 months old, not the 110ah I though. I think the battery is poorly in addition to whatever the draw is. I've emailed Hatfield Audi regarding the alarm siren and sourcing a new one. I've read on vwaudiforum a thread where the alarm siren was causing constant draw due to battery failure as it is always on regardless of the BCM
