Short story
I had my Haldex serviced by a local mechanic and shortly after i started to get a loud thud where reversing. This got worse to the point that it turned into a bang that felt like one of the brakes were sticking on and suddenly letting go. This was cured by§ removing the fuse for the Haldex. I had a local Indy JLR specialist do a further service on it who phoned to say he didn’t fix it but when he drained the oil it was full of metal particulate. I am presuming that this is the internal parts banging resulting in the above.
My question is has anyone else had this and would it be the whole Haldex 4 i need to replace or just the pump.
Tried Bell but they are not answering their phone this week or taking orders as they are too busy.

The pieces of metal in the oil won't be from the pump, sounds like damage has been caused to the haldex internals unfortunately but best to speak to the expert on how to resolve the problem. Landrover - turning owners into mechanics since 1948

I now fear that it could also be the team h that it connects to in the diff. Or is that not a possibility. As you may tell I know nothing.

My advice is pull the fuse so no further damage is done. Wait for Bell to come back off holiday and let them have a look.

There are some excellent LR specialists who know the Haldex system very well, but finding one  Tangiers Orange - gone, missing her
Replaced by Ewok what a mistake - now a happy Disco Sport owner

Heard many stories where after servicing the Haldex, at some point after, it locks up and ruins something...
There is something fishy here... Maybe a wrong way of servicing it or maybe a wrong type of oil used?...

The Haldex now doesn’t engage at all so the JLR Merchanic I took her too is getting me a salvaged rear diff with haldex that has a 60 day warranty with it. Not really the option I would ideally pick but we will give it a go. Ivan said to get a post 2012 diff so the nose bearing is the better one. I have insisted on this. MY06 FL1 TD4 2 door red (gone)
