Unfortunately, I'm not sure if they havent been working since before my warranty gave up or after, but noticed the other day my child window lock switch seems to be broken.

It looks like everyone on this board has had the dealer replace this under warranty. I'd like to go about doing this myself and was wondering if this is even a reasonable thing to try? Do I need to order a new control unit or a new handle?

I have fixed this button several times on different audi's (another achilles heel of many Audi's window control units) by fixing the plastic piece that breaks and then re-conforming the plastic channel. It's just another button that we don't use much but since we love our Audi's and we want everything on them to work properly -- we fix it -- we pay we pay!

I just bought a new 1, had to put buttons/window switches off old switch on new switch since they had different looking icons then old switch.
