I just got mine from the dealership. 2011-2015 Volkswagen Touareg Prk Brake Switch 7P1-927-225-A-ZJU | VW Direct Auto PartsI bought a new switch from what appeared to be a reputable VW parts site (vwpartsnetwork.com) - but it came all scuffed up. Looked like it rubbed against the cardboard box so long, it wore into the surface of the switches & polished parts of them smooth/shiny. Bummer.
Anyone care to share links to where they purchased theirs? Was it in brand new condition?
I have a 2012 tdi sport lux and it works fine. Plug and play. Didn't have to code anything in vagcom.
