Hello, i am Vali from România.
I'm sure glad I found this club because I have te exact same problem.
I got a 2006 Audi A3 sportback 2.0 l petrol.
I have tested everything that you guys did, still got a drain of 1.5 or a bit more.
Monday to Friday all good because I'm driving to and back from work.
I live in a small town and no need for the car to move around so from Friday evening to Monday morning battery goes flat.
The car is locked during this time.
One think I noticed and it is being tested right now: the button on the driver's door that lock the Windows to prevent them for being open by children or whatever, it was always on(orange light)
Even so with the lock on you could still open all the Windows if you would play with the buttons a little bit.
I hope I made some sense 8n what i was trying to say.
I'll let you know how the test went.
Peace!
