same here with my 50 mid 2020. Purchased it one month ago as a Audi Plus car. My first Audi, and directly a shitty experience. After 1,5 week i noticed the issue of leaking water. Exactly the same like the pictures above. Wet roof, left and right, and wet feet area. I am now arguing with the dealer who shall solve it. The local dealer, for now, does not accept the claim to solve it as the factory warranty has expired. Still waiting the Audi dealer where I purchased the car for final reaction. Curious how this ends. Probably hand it over to a lawyer. How did others solve this issues?
