All,
I have decided to replace the door lock mechanism and the window microswitch on my passenger door in order to try to eliminate my alarm system problems. I have a thread here and on RennTech and pretty much it seems that the problem is with the microswitches, probably the window one, but possibly the door lock ones.
So, I looked on Pelican and they have the part number as 8N1-837-016-C-VAG. A quick search on that shows it is a shared part with Audi TT (and others) and possibly Volkswagons as well.
Is that accurate?
Thanks, John
