Ok, so I have a Scout, complete with Haldex and ESP. I know the Haldex is "semi-intelligent" and will shift power from the front to the rear wheels as the fronts lose grip. The ESP will limit power and (in theory) apply brakes to individual if required as wheels lose grip.

 

Which comes first? Do they work in concert?

They work well together in most situations but in extreme slippery stuff, sheet ice or mud I've found it best to turn ESC off.  Tries to prevent wheel spin to the point it will brake all wheels & stall the car on steep ascents or descents (i.e. all wheels are losing traction). Caused mine to become an expensive toboggan on an icy slope so have learnt that sometimes a bit of human input is necessary.

Yes agree, on slippery terrain or when need traction turn TCS off, let the wheels spin and pickup if they can, without being limited by brakes.

In normal conditions I find haldex comes first. Push into a corner too hard and it will understeer for a moment before power gets applied to the rear and tightens your line. Great fun.

Likewise try doing an aggressive start in the dry. You'll just fly away. In the slippy stuff I find fronts loose grip, then the backs then traction control cuts in.

At least that's what I think happens. Most folk claim they can't tell when power is being shifted but it feels quite obvious to me. Might be placebo effect?

I have felt that happen once or twice.

I suspect this will happen more often in October, which I when I've planned to get the remap done

In very bad conditions turn the electronics off and use manual feel.

Get some decent tyres as a 2wd on the right tyres will always better a 4wd on the wrong tyes.

Whilst I accept it is far less effective I much prefer second gear, foot to the floor.

 

I'll still be stuck but its far more fun

Great answers guys.

 

I have to admit was was thinking more in general and in motion as opposed to snowy conditions.

 

Really can't wait for the snow to get here though

That's what I thought last summer. Had my winter tyres on and the scout was ready for adventure! What happened... Hardly as much as a frost!
