Just spent a little time checking the connections made near the X1 connector,

Pin 93 - Battery voltage - reads 12.7 v - OK - that's what i'd expect.
Pin 9 - Signal from front fog light switch - reads 12.7 v ???? Pressing front fog light button makes no difference.

Before i remove the instrument panel to check wiring as follows

Light Switch >> Instrument panel >> X1 connector pin 9

Has anyone else had the same issue and did you get it sorted?

Many thanks in advance. Looks like i'll be chasing/checking cables next week when i have a spare day or two.
