Well i tried to join the crossfire club but never got a reply.
The guys that have tested it have given me the following quote.
Headlight (NEW) £800
Body Control Module £1120
Labour £640
Coding £120

This was their diagnostic report
"Diagnostic Report

Have ran full diag on vehicle and no codes relating to fault described bit didnt access the bcm

Managed to gain access to bcm (after a few love taps) and found it wasnt communicating to the immobilizer module reset it and it was working but lost communication again and could gain access to it

Tested lights and found resistance was higher in driver side light signs of corrosion

new bcm and headlight to fix. may need to come into garage to code in"

They said they can fit a pre used bcm but it would need to be virginised. Whatever that is?
Not sure if i should just sell it and what it would be worth.
