Excellent! In the second video (cross axle) one front wheel is off the ground but not turning. How come this does not happen when on a slippery flat field - where one front wheel will spin and take all the power. This is obviously a setting on the traction control but which one? I have a lot to learn...
That doesn't sound right, this will happen if all 4 wheels are turning at the same/similar speed, fooling the car into thinking that it is actually moving.
You really need to select the correct Terrain Response setting for the situation, as Andrew said, you should go to the Land Rover Experience course. I've been on it a number of times (Defender V8, Td5, Puma, RR Evoque, RR, D4) and every single time I've learned something new. --

AndrewS is spot on - got out of the car last week at the LRE day to have a leak and a fag whilst in the forest bit ....... could barely stand up and could no way walk where I had just driven the D4.... could barely walk at all mud and crap everywhere - I slithered back to the car and hung on....!!2016MY Discovery HSE - Black

These videos are an eye opener. Surely the traction control system should recognize the wheels are spinning and stop them. This is a big problem with a system using brakes instead of and LSD since it can't brake both wheels but ought to reduce power and increase torque to each until they spin.
Are there any 4x4 drive systems that can handle this slippery grass *without* special tyres? I have the standard tyres but when I had arguably the worst tyres made (BF Goodrich M&S), it was no better - possibly worse wince they are totally symmetric and after one turn they filled with mud and snow and became slicks..
Yes, but TC will only calculate a spinning wheel relative to what the other wheels are doing.
As the example of the RR shows, if all wheels are spinning away, the car thinks it's driving normally. At least that's how I understand it.--

Yes and a LSD will do not better as when there is the same no traction to each wheel both will turn as if the LSD was a locker.
More learning is required - me thinks.

A pity there is not a ground speed indicator to tell the car it isn't moving.
Does anyone know what settings each TC setting uses?
And yes, a bit more learning for me!
thanks

Something tells me the 4x4 manufacturers are trading on image alone. Check this out:
Topgear. Taking rear wheel drive estate cars through places most wouldn't take a 4x4

From the manual...
you could try turning off DSC and selecting mud...
Sill protection - LED internal lights - LED reverse lights - boot liner - Dog Guard - Rock sliders

When on a LRE I explained to the instructor that I was stuck in a field with a slight incline due to the loss of traction through tyres being full of mud. He said they call it green ice..its as simple as that. He said try off-road tyres but as a previous post said when there's no traction 'there's no traction'! It was the thick clay type 'summer mud' very sticky and slick. I guess its similar to the type you would find in the Alps? Perhaps the correct tyres for the conditions are required. In the end a good run up and more 'power' worked well enough but it wasn't pretty!!Following my success I was approached by someone who suggested I read the manual... :oops: he was of course absolutely right. Which reminds me I should actually read the manual...
