Hello Holger247!
I spoke with the friendly person on the phone today. They said that there is no repair kit available for my engine, but only for the 8L0 955 711 type.
Hmmm, I don't really believe that, but what can you do? They want almost 28 EUR

for the repair kit. Now I've bought a used one in almost perfect condition from ****.
By the way, my rear wiper motor already has the plastic housing. I bet the repair kit would fit...
I immediately had two engines with broken brass tubes lying around after the exchange (one from an A3 and one from a Golf), so I can come up with my own repair solution for both

.
Regards,
Alex.
