I have a 2007 Transporter T5 on which both electric windows suddenly stopped working. I tried the fuse and all obvious things before narrowing it down to the driver’s door motor/module. Looking on eBay there were a few available but they were all about £130! I called my local VW van centre who told me the part 6Y1959801 was now obsolete so they could not supply one! I was surfing around the internet and came across this thread and contacted Breezy_Pete who was staggeringly efficient in his communications and offered to fix it, I sent it off and it was turned around the same day. I cannot recommend Breezy_Pete highly enough and my sincere thanks for getting me out of a hole at a fraction of the cost of a second-hand unit.
I have no connection to him but am just a VERY satisfied customer!
