Hi I'm new to this forum and i've searched around a bit, but I wasn't able to find any answers. What I want to know is if the VW dome light below will fit in my 1999 A4 Avant and if the sunroof switch will work the same because i've heard some Audi and VW parts are interchangeable. The reason i prefer this or other VW parts is because all the Audi ones I've found are in terrible conditions.
