Are the rear passenger windows from a volkswagen passat and an Audi a4 the same?

What is your question?

I broke my Audi A4 B5 rear passenger door window and have had some trouble locating one. I have located a 2001 VW Passat and want to know if they are interchangeable,

How long has your 1999 Audi A4 had this problem?
