I know for the most part that this forum and the Land Rover world are already well aware of what a Haldex is, what it does, when to service it and all of that stuff. But I know there still is a large amount of Freelander 2 / Evoque owners (new and existing) that don't know that they have a Haldex on their car. Or if they do, they don't take it to somewhere that will do a full and proper job. With the help of all of you, hopefully we can get the message to those people.
If you don't want to read this post, I've done a quick 4 minute video for you to watch and share. Feel free to adapt this post and post it elsewhere on other forums and other manufactures forums that have a Haldex fitted to their 4x4 cars. Also, feel free to share this video to help make others aware that they have a Haldex fitted to their car and hopefully save themselves time, trouble and money by having it serviced before it fails.

(Yes I know it's our Yeti in the video and not our Freelander 2, but it was just the car that we had handy at the time of filming the video ).
What is a Haldex?
This is probably a terrible explanation but here we go. In super brief and simple terms, a Haldex system is a component that sits between the prop shaft and the rear diff. The job of the Haldex is to pretty much let the car run in front wheel drive in increase fuel efficiency. As soon as the Haldex system notices any form of wheel slip, it engages drive to the rear wheels to help aid with traction.
Why have I made this post and video?
A Haldex system has been fitted to alot of different brands 4x4 cars out there and there is alot of people out there that don't realise that they have this Haldex system fitted to their 4x4. My aim is to bring awareness to those people with the hope that it will save them many pounds in the future.
Not only that, it's also to bring awareness about taking your 4x4 to the right garage. Some garages won't know what a Haldex is! Some may know what a Haldex is but only do half a job when it comes to servicing it which leaves you both out of pocket and with a Haldex that may as well not been serviced. I'd say that there's a shocking minority of garages out there that know what a Haldex is and how to fully service it.
What do you mean by fully servicing it?
I'm going to discount Gen 1 and Gen 2 Haldex's as they are fitted to very old cars now.
Gen 3 and 4 Haldex: These need o-rings changing, haldex oil draining and replacing, filter changing and most importantly, pump removed and the filter on it cleaned. The pump filter is what often gets missed by alot of places. Or even places saying to customers that the pump doesn't have a filter.
Gen 5 Haldex: These do not have a replaceable filter, so it's just o-rings that need changing, haldex oil draining and replacing and the screen on the pump needs cleaning.
Even if you take your car to a Land Rover dealership, firstly, you might have to get them to acknowledge that the Haldex exists . Then, if they do acknowledge it's a part that needs servicing, you may only be getting a half serviced Haldex! Often the pump filter is overlooked.
When should it be serviced?
General guidance seems to be every 2 to 3 years. Or if you're a high mileage user, every 20,000 miles 'ish.
What goes wrong?
Inside the Haldex is what looks like a series of small clutch plates. As these bind together to deliver drive to the rear wheel and release when drive to the rear wheels isn't needed, the material wears off of the plates and is discarded in the oil. This junk is either caught by the filter on Gen 3 and 4, or caught by the filter on the pump on all the generations of Haldex.
Over time this builds up. As you can imagine, the oil turns more to sludge, the filters get more and more blocked and the pump has to work harder and harder to do its job. Then one day, it'll just give up and you're in for an expensive bill.
Best case scenario, it's a Haldex service and a new pump. Worst case scenario, it's a whole new Haldex!
Can I service the Haldex myself?
From what I've seen, from the pump location, it can be a bit of a pig to get it removed. Other than removing the pump, I don't think it's an overly complex job to carry out.
Handy links.

Alana and I have recently taken ownership of a 4x4 Skoda Yeti that you see in the video. This is the state of the pump after 65,000 miles! What you don't see from this image was the large amount of junk that was built up by the pump that come flooding out!

As I have said in the video, if this gets 1 person to service their Haldex and avoids it failing, then I'm a happy man. Hopefully I've covered most stuff. All I have left to say is happy motoring all 😀.https://www.youtube.com/@scottandalana4x4

What he said...
Good video Dean1234. I was planning to service my car's HALDEX anyway, (this summer, when the weather has improved), your video has me even more convinced that it will be time & effort well spent...
