May have found the culprit..
working back from diff module connector, probably circa 400mm up the cable
View attachment 334722 View attachment 334721
Situated directly above the haldex, the cable disappears over the rear sub-frame
Access is tight, so might try removing some cable ties then withdraw the whole harness back into the car ( boot area)
to verify the true extent of the damage..if that's possible?
Will keep everyone posted
