Window lifter

Hello, guys.

unfortunately I did not manage to repair my torn rope hoist! That's why I went to Audi and asked what it would cost. I was told that before the 93 year of construction, where the rope hoist unit can be bought separately (ca80€) only the whole thing is completely so rope hoist and motor available (ca200€)! and there my
Year of construction 92 is...
So I wanted to ask, does anyone know where there is the difference between the systems? wouldn't the new rope pull system be combined with the old engine?!
I'd be happy to hear any suggestion! Thank you in advance.


Greetings Rainer
