Hi George,
Got the car back from VW and managed to have a look. The blue wire connects a white wire with a red line. I have taken some photos and attached them.
The plug and wire connect in the following order:
Black (6) - Yellow (6)
Blue (5) - White/Red (5)
Grey (4) - Red (4)
Dark Yellow (3) - Purple/Green (3)
White (2) - Grey (2)
White (2) - Grey/Black (1)
It would appear that there is a wiring plug attached to pin 1 & 2 which is a white wire then this connects to pins 1 & 2 on the connecting plug which are Grey and Grey/Black. You can see this in the photos.
Cheers,
David
