Okay little update. I put the car on the ramp, had a look and saw that the earth strap was actually snapped. Sighhh of relief when i saw it so stripped the wire back and bolted put it directly onto the earthing spot and used the metal piece to hold it down tightly. Put the haldex fuse back in, took it for a spin only to find out the issue was still there . Plugged it into a launch system and ran the haldex checks again but issue is still there.
Cheers for the link tuffty I just checked through it and im going to have a look at that connector today and see if thats causing the issue. Hopefully *fingers crossed* that could be the issue and i could put this haldex issue to rest lol.
Once again thanks a lot for all the help!! :D
