I have now done the following things:
Evaporator and blower housing removed, but I removed my bonnet for that, because one does then do themselves a lot easier, as Jenz is right. But I also had to dismantle many claddings in the interior. But when I had everything out then I had to find out that you can't open the evaporator housing for cleaning. You probably have to buy a completely new housing with evaporator at Audi. Well, I didn't do that, because my evaporator was just totally dirty, but not broken. I then carefully opened the case on the plastic welds and then freed the evaporator from the coarsest dirt (original foliage, bird feathers, ancient ticket from the predecessor etc.). Then I soaked the evaporator in the bathtub (connections sealed before). My girlfriend almost killed me!!! You should've seen what kind of "brother" was formed, the absolute madness. I then let the evaporator soak for a few hours and then gently felt through the lamellas with plenty of water and, look, the thing looks like new again. My girlfriend calmed down after I cleaned the bathroom.
Now I've been thinking about how to get the evaporator housing back neatly and tightly. For this I am then to our VAG dealer here with us in the place and that gave me then a black special glue and that also for free. I then glued the case again and this glue now holds the case together so tightly, I think that now holds better than before.
I also opened the blower box, but it was a bit easier, because there are extra clamps and screws. I changed the heater cooler and the blower for a new heater cooler and a new blower, because the heater cooler and the blower did not look good anymore. Manfred was right about that!
Now I have also installed everything again, but of course also with new hose clamps and new seals for the air conditioning lines. Water and G12 I have again rein again and after extensive test run I could find out, the "modriege" smell from the ventilation has disappeared and now it smells really pleasant.
Today I have to reassemble the motor, reinstall the wiper rods and, of course, reassemble everything from the inside.
In the next few days I have to have my climate filled again and that costs at least 70,00 € again.
