DSC?
Can anyone please tell me the purpose of this function, My Disco has this switch on the dashboard now is it meant to be on all the time or off? What is it best used for?
When i push the switch in a orange light comes on.
I have read the owners manual on the subject but i am finding it difficult to understand,
regards to all.
looking forward to Snowdonia!!Steve

DSC is dynamic stability control. It keeps your car where you want to go it if you are just going over it's limits.
Say if your are going to fast over a roundabout and it senses that your steering input is bigger than the turn the car is making it will first take the trottle input down and if that's not enough it will actively use your brakes to make sure it will react as you steer it.
The system should on the road always be on.
You can switch it off but you don't switch off the whole system just the first bit taking back the trottle. This is handy when offroad or in deep snow. So in cases where you need power and don't mind a little wheelspin.
Your traction control will still be working.
You can try this on a piece off zand where you can make a few circles on full power. First do it without DSC switched off and you feel its controlling the slide by cutting back on power. Stop and feel the heat coming off the brakes (don't touch them as the are hot) Thats the traction control/active braking part.
Now do the same with dsc turned off. You see that the revs don't come down and your traction control is working it's ass off. You will see that you need to steer a lot more to do the same turn at the same speed.
If you stop now and feel the brakes you probably don't have to come close to the brakes to feel the heat.
I hope this makes it a little more clearRoel

and just to be clear, Traction Control is ON by default. When you press and hold the button the orange lamp is warning that it has been turned offI know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.

Traction Control is always on
Dynamic Stability Control is on by default and you can disable its early intervention, but it cannot be totally disabled (I am led to understand). Essentially it is disabled though.
DSC should always be on unless you are attempting to climb a particularly difficult slope where the D3 may slew left or right while you need full power. The system will think you are skidding and cut engine revs and start to brake any offending wheels.
I usually forget to turn it 'off' and have rarely been caught out.
LEAVE IT ON UNLESS YOU KNOW WHEN IT HELPS TO DISABLE ITS EARLY INTERVENTION.

The braking part it will still be working. It only doesn't cut back on power when you switch it off.
Try to do the circle as I described with DSC off. The brakes will get hot so traction control and the stability part still work.Roel

This is the most important bit Rich.
Turning it off and then finding you slide off the track as didn't kick in to help save your D3 is a bit of a .

Well the type of test you are carrying out may not be extreme enough to re-engage DSC operation ... if however you did a high speed elk test you would find that it's likely to kick back in when its been switched off 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021
