for the conversion and registration of UFO on HP2 I already drew the fax from Audi from 1999 and the letter copy here from the forum. But it is modest to recognize.
As Thomas reported, this should be enough for the entry in the papers.
Are there any more experiences and documents that don't force the TÜV to kick me out?

Oh yes, actually I wanted to install new UFOs again, but they went almost 3 weeks behind me at VAG

So I now convert to HP2. I've got one. too hot, maybe. but after 7 months to have again crooked windows and 2. who knows how long they will actually be produced.
I really wonder why Audi doesn't take care of getting the joungtimer. It's a sign of durability. There is clearly better sorted MB.

Thank you for every additional info about the entry!!!
