Slimer:
I'm guessing this is what you rang me about Jake? Sorry I missed your call, was playing in some Welsh mud and phone signals were bad at best

Mud and Ruts should do what you want or try Rock Crawl which will make the centre diff lock more sensitive (and the rear one too if it's fitted). If you haven't played with the suspension it will automatically raise when you select one of the off-road modes, if not just flick the lever, if it detects you've bottomed out and it's sitting on its belly it'll go into extended mode and automatically give you a couple of inches extra height on top of off-road height, if this happens (it'll tell you on the dash display) put your foot on the brake and hold the height lever up and after a few seconds it'll go up a bit further still. No it doesn't lower when the door is opened so if it's in extended-extended mode you might need a step ladder to get out :wink:

Same with low-range, just flick the lever, the message centre display in the dash will tell you what's going on

Leave DSC on, Sand mode is the only one you'd turn it off in straight away, if you're getting nowhere try it with it off but I doubt you'll need to. Remember the traction control works by sensing wheel spin so if you get stuck give it some revs and let the electrickery do its stuff but you'll probably find it will go through most terrain much slower than you're used to, i.e. no need to boot it as much as you'd think. It is bigger and heavier though than D1s, D2s, 90s, 110s etc so you may well get stuck in places they don't if you get bogged down, keep it moving and you should be fine

Back at home now complete with phone signal so feel free to give me a call if you want

Thrasher:
Slimer,

I beg to differ with you about DSC. It might explain why I have seen D3's stuck in places you'd never expect (i.e. while turning a corner and going up a hill). Essentially if you leave DSC on, the vehicle will act as if it is on road - when you attempt to drive up the hill, there is the possibility that a wheel can slip. When this happens, your natural reaction will be to lay down *more* power to get over the obstacle. DSC will counter this and will sap your power - that is what it is designed to do. Hence you will in effect be stuck - not enough power to get the heavy D3 where you want it to go. I would NEVER use DSC in the situation Jake was in - wth wet "road" under the tyres and offroad - it could sap the power and prevent the bow wave from forming properly......

If you have never had DSC come on - I guess you'll not know what I mean - but an easy way to get it to activate on road is to take a deserted roundabout and go round it increasing speed. Once you exceed the envelope for DSC it will cut in and the power will be taken away.

Land Rover Experience and the handbook also state that it must be switched off on the full size RR - as it is the same system, I can only assume the same rule would apply.

As an aside you can also activate DSC by going over wet speed bumps ....

Slimer:
Really depends who you talk to (including at LRE) whether you should turn it off or not Neil. The RR doesn't have Terrain Response yet (will do very soon though) which is perhaps why they say turn it off all the time off road. Having regularly driven a D3 off road for over a year now I've rarely needed to turn it off and very rarely got it to cut in too.

It doesn't actually go off anyway, it just 'holds back' and will still cut in if you really over do it. Don't know for sure but I suspect the DSCs 'sensitivity' adjusts too along with the throttle, gears, diffs etc. in the various TR modes, it's definitely seems less sensitive than in 'road mode' and takes a lot more before it cuts in. Traction control will normally be doing it's tricks long before DSC cuts in.

I've done the roundabout thing (in a V8 RRS), lots of fun, by easing off a tiny bit when the DSC cuts in you can then build the speed up a bit more each time before it'll cut in again.  :D

Thrasher:
The FSRR gets Terrapin Response this year (Oct) - it has meant they have redesigned the centre consol and made it look it cheap and tacky :( One of the reasons (not the only one!) why I may take a long hard look at Bagheeras replacement.

Adding TR to the FSRR will no doubt cause lots of software headaches again as well.

Jake:
The owners hand book states when off roading the D3 to turn off the DSC
(I have actually read a hand book  :shock: )

On a lighter note, what are you doing this weekend Simon?
