Haldex- Should it be serviced oil + filter when a new rear diff is fitted??

New rear Diff -- should the haldex be renewed/serviced at the same time.

Hi,

MY15 Dynamic Lux 2.2 SD4 with 45K miles on clock is being fitted with a new rear diff under warranty. As it appears that the Haldex unit may cause problems with the differentials should this unit be changed or at least serviced with new filter & oil at the same time.

I asked the main dealer how much it would cost to service this item and was told " There is no need to service the Haldex" as it is not mentioned in their manuals etc. Or indeed the handbook. Because of that they do not, & they could not even give me a price to do this job.

Is this correct as it seems that many people are saying that the service interval is approx. 20k miles?

Any info would be much appreciated as the job is being done tomorrow.

Many thanks in advance.

Bazz,

Contact bellengineering.co.uk They are the experts in diffs and haldex.
I ordered the haldex service kit for my Evoque after being told by the dealer that it didn't require servicing. Audi replace the oil and filter in theirs. Go figure lol

When my local garage did the kit, the colour of the oil drained out was something else!
£78 for peace of mind, well worth it!

Thanks chez,
I have seen their ad & watched the video, this makes JLR look very sad when they say it does not require servicing.
I am still wondering whether this has caused the original diff to fail enough to need replacing. I had hoped it could be done at the same time as the diif was replaced, in the hope that it would ensure that the diff remains in good working order, I did ask the cost for this & was told we do not do this at all, very strange. It surely would make sense as it may have been this that caused the diff to fail.Question

Cheers,

He said that when diff is removed the oil will be lost from Haldex pump so it should be replaced.
It would make sense to clean/replace filters at the same time or replace the Haldex unit.
I am still waiting for a call from dealers.

With earlier cars the Haldex fluid was originally “sealed for life” but after a lot of failures JLR decided that life was 3 years......... so on 2011 to 2015 I believe the oil is supposed to be changed every 3 years. I don’t know about later cars with smart disengaging rear drive and how that has affected the Haldex servicing.

Now driving a 2018MY Mini Countryman Cooper S E All4 PHEV, alongside my 1996 Defender
TDi300. I hope to be back in a new Land Rover in late 2019 or early 2020 but am having a short break
To try something different
