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???

Thanks for the reply the fuse was fine, when I get time and £££ iam going to pull out the pump and filter and have a look as I also bet it's all blocked up.
As for the fuse I pulled both and all quiet on the haldex front for now.
Not a job iam looking forward to as they didn't make it easy to do.
