I found that some fuse locations didn't tally with the handbook that came with my van. (Early Mk7 and new handbook.) Led me a merry dance with a headlamp problem.
The variations are in the Standard Relay Box behind the glovebox.
Fuse Early Later
39 10A dipped beam Right side 10A Front & rear air con control
41 10A dipped beam Left side 5A Tachograph
50 10A Front & rear A/C control 10A main beam Left side
52 5A Tachograph 10A dipped beam Left side
53 10A main beam left side 10A dipped beam Right side
Hope this helps.
