E diff?

[shorty]

Not sure if my attachment worked but if it did can anyone tell me if this car has the e diff based on the info screen photo?

The pic is from a 2011 D4. Thanks in advance!

Yes, green lock on the rear diff in the pic on the left is the e-diff.

That light IIRC is there regardless of fitment or otherwise...

Need to check on top of rear diff for wiring harness to be certain its fitted

PM me the VIN and I'll tell you for sure.

That's interesting and must have changed for later models. See photo of mine, showing only centre diff symbol (MY14).

Yes, when the infotainment system was updated late 2012 (I think), LR dropped the "always there" rear lock symbol. You also get the incremental lock indicator on the newer models.

Came into effect with MY12 (i.e. 11/2011 build date)

On a similar subject - I have a 2010 2.7l D4 that didn't come with the e-diff however, I've crawled underneath and after checking a mates 3.0l D4 with an e-diff - all of the associated plugs to accept the e-diff wiring are part of the vehicle loom.

I've found a couple of companies that can sell me a complete overhauled e-diff for thousands of $$ less than actually buying one from Land Rover and, they have confirmed that the diff could be a direct replacement for my non e-diff.......for under $2K!

So.....It seems that it is a credible possibility to fit an e-diff into my D4 and enjoy the advantages without the significant expense.

Couple of things that I need to confirm although so far, research suggests it is possible.
1. Will the ECU recognise the addition of the e-diff (It seems so as the software is part of the ECU but not being utilised on my non e-diff system)

2. I'm aware that I won't have the goochy electronic display on the dash as I don't have the upgraded entertainment system (But I could live with this knowing the e-diff is doing it's job although not actually showing me on a display)

Next step is to buy one and see if it all works :cool:

Does the 2k also include the "Rear differential control module" (ECU)? Unless you can find one second-hand they can be expensive!

[Graeme]

A new rear diff module was 234 GBP earlier this year.

You should probably fit the stronger CVs too, possibly with stronger half-shafts.

Does the price include the motor?

Someone on disco3club.co.uk did it.

Yes it does Graham - the company is based in Sydney and are diff/gearbox specialists. It is a complete diff - not just the centre.

Big thanks to Dan as well for passing along the UK D3/4 link that shows it has been done before. Gives me more incentive to get this project underway for literally a quarter of the price of buying the bits new or....buying another D4 with the electronic diff fitted!

[Graeme]

Which company?

I costed an e-diff conversion for my model 4.4 TDV8 Vogue earlier this year at approx $8K ex UK for new/refurbished diff components, new control module, the combination wiring loom (75 GBP) and freight. Retro-fitting to the Vogue is easy, as would be the D4 if the connectors already exist, with only CCF activation once fitted. The 8K cost is not so easy to accept.

The Vogue does not use the same housing as the D4 but as supercharged Vogues have an e-diff standard then I've considered getting one and having my CW&P fitted rather than buying new. BTW, the MY10-12 Vogues use the same e-diff control module as the D4.

Let me know how you go as I may be interested in doing it in the future.
