OK, so the latest thing (in a long line) to go wrong with my wife's 2007/57 FL2 is the Haldex.

It was fitted with a Generation 3 Haldex, so the issue was how to repair or replace this for as little as possible.

The standard options seem to be:

1. Find a second hand Gen 3. Cost variable!
or
2. Pay a fortune for a 'specially adapted' Gen 4 - only available from Land Rover. Cost £2,000++

Well - there is a middle way to adapt a new, standard Gen 4 (cost circa £300) to work with a pre-2009 FL2. The 'extra' cost for parts is about £600 + VAT, so total parts cost is about £1,000 - but still substantially less than buying an 'off the shelf' adapted Gen 4.

My indie LR specialist worked very hard to find this solution, so in deference to him, I'm not going to broadcast it here, but if any established members find themselves needing to replace a Gen 3 Haldex on their car - please feel free to PM me and I'll share the solution.

Hi Calc,
Is the solution to this issue software related? I was wondering if perhaps Autologic can fix the transmission faults and makes the gen 4 haldex work on my Freelander 2/2008.

Hi - No, it's hardware. LR sell a part which allows a Gen 4 to be adapted to replace a Gen 3. But seemingly almost no-one knows it exists. It isn't easy to find and doesn't show up on most parts searches etc. But, if you know it's there and / or know the part name or number (not sure exactly which) - it can be found and ordered from LR. I believe it is then relatively easy to swap over and fit.

LR014073, Haldex GEN4, compatible with GEN3, SERVICE ONLY, (8H999799 to 8H999999)

Its funny cos according to Microcat, LR014073 matches my car, but in fact it didn't. Alex, you saying that GEN 4 only matches GEN3 cars with vin between 8H999799 to 8H999999?
Calc, thanks for the info. I will ask headquarters in UK and see if I can find out more about this part then. Cheers.

Good luck. I don't think LR make it easy to find or even to find out about!

Thank you. I just don´t see a reason for LR to hide this information to their costumers.

Whats the benefits to change haldex 3 to 4? allready one broken diff, and when i changed it i noticed some " scrats, wear on haldex bearing. Incase of haldex failure someday, might be vice to change it to gen 4?

OK, just to share here what happened: I replaced my GEN3 haldex with the GEN4 part number LR014073 and all commands for terrain response went faulty. So I took the car to the dealer and at first the computer was not recognizing the new part. What they did was trying to update the ECU software using an older machine which has recognized it and it is now everything working perfectly fine. Costed me nothing cos the car was already scheduled for maintenance services. So lucky...

It's possible that the new Haldex ECU, being a "service only" item, to come blank from the factory and to need to program it anyway with the right software.
See it like a blank CD which need to be burned with the right software installation kit in order to be useful.
Anyway, glad that you sorted it!
