Hi all, have checked the items you guys have suggested and all looks and test's fine,
To narrow it down is it possible to con test the loom from the LCM to the individual light holders, as in is there any other modules I should look at or are in the circuit??

I have done the following :-
Cleaned and checked ALL earth bonds
Earth's at the bulbs
Tested all bulbs
Tested all the fuses and fuse links
Visual of the loom
Tried a 2nd hand LCM still have the same faults
Tearing my hair out a bit now,
all help and advice well received

Just to be clear. You have the same faults with BOTH LSM's ???

I believe so, now I have played around with everything I think it would be a wise move to plug in the 2nd LCM and try it all again.
I'll keep you all posted with the result

Have you checked to see if there is 12V actually present on the brown and light green wire at the LSM?

I have to ask this as the faults you are describing can be replicated by removing this supply feed.

I've had a few of these in the past, it's almost certainly the connection to the underbonnet fusebox.

Undo the fixings to the underbonnet fusebox and then unlatch and re-latch the connectors under the fusebox and hopefully that should sort out your problem.

Thanks BigRuss, you were spot on, I could hear it arc when my Mrs put the brake pedal down,
Pulled the fusebox out and re seated all the plugs and "hey presto" all the lights work as they should.
I can't thank you guys enough for your help and advice
