I know haldex has been mentioned but can I ask what the haldex unit is seen a fl2 says had a new haldex unit fitted what would the reason be for, is it something that needs replaced periodically

I know I need to check that water pump and belt changed, do any fl2 run on chsind

The Haldex is an “on demand electronically controlled clutch” that is fitted between the end of the propshaft and the rear differential. It works with the terrain response system to control drive to the rear wheels.

Haldex is effectively an electronically controlled clutch that engages drive to the rear diff if the car senses loss of traction - in normal driving conditions the car is front wheel drive only.

Rear diff is also a weak point, bearings fail as they're not strong enough. Look for a car that's had a replacement diff from Bell Engineering.

Best advice is look for a car that has a full service history

Its not unknown in FL2s because JLR did not put servicing of the haldex in the scheduled servicing so the units dont get the necessary oil and filter changes and can wear out beyond 60K miles. JLR preferred owners to have to pay for a new haldex.

Other users of Haldex systems (eg VAG and Volvo) have regular mandate haldex servicing - the frequency depending upon application but can be every 20000 miles. Jules

The servicing is not very technical, just very awkward and time consuming - its DIY-able. So to keep servicing costs down JLR just missed haldex servicing off the list. Jules

I drive a 2007 fl2 that I’ve owned since 2010. I’ve had the Haldex serviced at Bell while they were changing the diff. Most cars that use Haldex recommend that the oil is changed regularly. JLR say that the Haldex is sealed for life. I’d say that it is no more expensive than anything else on these fairly complex vehicles. It can cost £1000 to have the clutch and DMF changed on a manual.

Bossbob I’m having a blonde moment what’s a DMF, have no chance of diy, I can change a battery and that’s it

Maybe my local mechanic putting off as he says only decent thing they made and stopped making them, he says sums up LR For you

He said he wouldn’t have one as a gift

Dual Mass Flywheel, a device fitted between the engine and clutch that absorbs vibration at low engine speed. As a huge portion of the cost of having the clutch changed is labour and the dmf is accessible, you’d normally change it at the same time.

Exactly - the life of which can be quite short if not serviced.


I imagine servicing a haldex, say every 30K miles, would add a significant cost to the annual oil and filter change. It would bump up the all important total servicing costs during the initial 3 year warranty period. Jules

Audi, Volvo and the others that use Haldex are not afraid to specify servicing intervals for their vehicles. AFAIK it’s only JLR who think that it’s disposable.

My Freelander had 154,000mls on it when I sold it and it still had the original haldex (and oil) and still drove like a new car. It was still running the original clutch, shockers etc etc It was 6 years old at that point and I had bought it when it was 4 1/2 years old with 132,000mls on it with full LR service history as it was a lease car. I had no trouble with it or any DPF issues despite only doing very short commutes Monday to Friday. Currently have a D4 Euro 6 which again has had no DPF or oil dilution issues during the 7 months /7,000mls that I have had it again doing 5 miles to work and back each day. It gets a longer run most weekends but I do not go out my way to give it a run, just my normal running about.
