Long time no see you….
Hi friends, few months ago I sold my TDV8, but until now, nothing was the same on my long trips… so; ones again, I need one!
I am seriously thinking to buy a 2010 MY 3.0 TDV6, and I have a doubt.
My previous RRS and of course my D3 G4 have the rear differential lock; I am not sure if I really need to pay for that, if the primary use this new RRS will be on road and sporadic medium off road. But, how this car works on snow road without the rear diff lock? It means, if I go to a snow place; may I affront“snow” roads? Or I need the rear dif lock to do it. If I am right, the previous Land Rover models, like Discovery 2, were without this option: only central lock like the Defender. I don’t remember any rear dif lock on my 02 Defender….
So…… rear dif lock, or not!!! Welcome opinions… Yuri

Go for it - it's well worth the price and can't be added later on.

Waste of money in my book.

From other postings and web sites it would seem the general concenus is that it makes it a little easier with than without but you will still get through without it, though it is not as controlled in extremme conditions.

The traction control is way superior to the Disco 2 and this is why they then had to fit a diff lock as an option later on.

If it is only going to be used for medium off road use then would say it is overkill.

Save the money and buy a second pair of rims with off road tyres or snow and ice and this will benefit you more

Personally the 2 RRS's i have owned haven't had it fitted and its not been missed, but if you can afford it and think you may need it then buy it  MY10 3.0 TDV6 HSE, Zermatt Silver, 20" Diamond Turned Alloys, Factory Privacy Glass, Premium Leather, Contrast Stiching, Side Steps, Etc

The RRS doesn't really need it imho. When I've been off road I've only had the standard rear diff and my RRS got through places where cars with the rear diff got stuck and vice versa. 2005 Zambezi TDV6 - Gone but not forgotten

I have never quite understood what the rear locking diff achieves when combined with the electronic traction control (ETC - that is standard on a RRS).

On my Defender (without ETC) I fitted a rear locking diff, so that if one rear wheel lost traction, the other rear wheel with traction still got power. An important addition - albeit expensive - especially when the rear half shafts broke due to the extra stress the diff lock threw at them.

But with the RRS with ETC, if one rear wheel loses traction the ETC stops that wheel spinning and diverts the power to the other wheel which still has traction. Surely this achieves pretty much what the diff lock achieves.

And if you need both rear wheels spinning to give you more push through snow or deep mud - then you can switch off the ETC. So (unless I have missed something here - which is perfectly possible - indeed quite likely) I can't see how the rear diff lock pays for itself ? RRS TDv8 HSE Rimini

Firstly let me say I'm not an expert in this space...

On paper I think you are 100% correct Smarticus.

However, I have found, in my personal experience, that I have sometimes have had to 'trick' the ETC to kick in using the brakes as or when the wheels have lost grip when off road. Particularly so when in bog holes, as sometimes the wheels spin and the car doesn't recognise lost traction.

I can well imagine that scenario - electronic aids to traction can be a bit tricky as they can be a tad too "clever" for their own good - whereas mechanical aids are more basic - but do exactly what they are told to do.

Strangely I feel this compelling urge to spend some time in a bog hole right now  RRS TDv8 HSE Rimini

The TC some slippage before it works the ediff doesn't. Cars equipped with it do make easier progress, but don't seem to be able to go any further. The skill of the driver is still the biggest advantage. Porsche Cayenne S Diesel 66 Plate

The rear diff lock makes a huge difference in some situations. ETC relies on braking spinning wheels to send drive to the wheel with traction. The diff lock, which engages in fractions of a second sends drive to both rear wheels without the brakes coming into play.

The difference is easily seen on very steep slopes with a loose surface combined with axle twisters or rocks. Probably not very common in the UK, but if you do go off roading in harsher parts of the world, then the rear e-diff is a necessity and in fact, comes as standard on all SA D3/D4 and RRS. All LRE cars have them too.

My experience with ediff is that it works much more smoothly and without any spinning especially in difficult situations like a cllimb in uneven rocky place for example.

What I realized is that you need to have low gear and rock crawl mode on TR to see the red lock on the rear axle in the 4x4 display (which denotes the activation of ediff). Maybe I'm wrong here.

The other benefit with ediff is that it DOES NOT use brakes for the job. 2009 Range Rover Sport 2.7 TDV6 SE, Alaska White, Almond leather, tinted windows, active rear diff, tow pack, HiICE, full spare: gone and already missed

Silly one but on the 4x4 screen, if you have a rear dif, it showns by having two locks as oppose to one lock only, right? Range Rover Vogue ‘17 TDV6
