As FREEMIND says they are available VW parts, and their parts guys used to be quite willing to look up parts/numbers. It has been a few years since I owned VW, but back in the day they we helpful. I found it helpful to them if you could bring them a sample to match the parts. BTW, I've found my local Ford dealerships parts guys to be always helpful went I inquire about parts.Are they not the Volkswagen plugs?
