This is my first time owning a VW and first time writing a post. Be gentle... anyway my a/c isn't working and my glowplug indicator light is only on for maybe a second. Replaced all glowplugs and still doesn't seem to be cycling. The manual says that #12 is the fuel pump or glowplug location. Another place I found that #22 is the glowplug relay with a 50amp fuse above it. Anywho, I bought a new relay, (not cheap), put it in # 12 and when I turned the key, instant smoke show from the relay. How many different configurations are there and which do I have?
