This may not be correct, but I ran a V70 R AWD and had haldex issues. I read lots much now alas forgotten, but IIRC the haldex pump has issues with the filter getting blocked ( certainly earlier variants and even later ones if the filter has never been changed) this caused the fuse to blow as the pump was overloaded, and AWD to cease.
Looks like someone has decided to "force" the pump to continue to work when it wanted to blow the fuse by adding extra wire. This extra current caused the pump to "complain" which was the noise you heard, and you may find the fuse is now blown, or did you pull that too - thats why its quiet??? Cheers Bob
