Sun roof drain may be disconnected or clogged( this is the most likely cause). It is found behind the trim on the upper half of the back pillar. I have also seen where the sunroof frame itself cracked causing the leak, only way to really see that is to lower the headliner a little and inspect for dripping water while spraying the top with water

If I am correct all the other volkswagen and Audi have to remove front end it will all come off as unit from light to light radiator as well

I believe it is located under the front seat. To access it, locate the trim panel at the base of the seat. Remove it carefully and you'll see the front seat attachment bolts. Remove the bolts and tip the seat back. You'll then see the battery cover and you'll have access to the battery.

Beside the dashbord left or right and inside the trunk left or right

check for something left on--boot light , phone charger adaptor--interior light. have a load test done on the battery and check for a failing cell as it may be discharging internally

With the white smoke....sounds like a blown head gasket or cracked head.
