Hi guys

I have a wiring issue which I need help in sorting out. My Xenon headlight range is not working and it would appear a bad earth is causing the fault - but I dont know where to start.

Scan done found 2 fault codes
00776
00774

According to ross tech wiki, bad earth / wiring??

Of course it could also be a faulty module - so I what I am wanting to try is swapping it with someone to see if this solves the problem before I shell out Ł190 for one!!!

If anyone can help i'd be most grateful....
