Having experience of the Haldex Gen 4 in the Yeti, it was brilliant and required hardly any wheel slip to get the back wheels working. The VCU in the Freelander 1 seems slow, crude but effective and an awful lot cheaper with no electrics and pumps to go wrong.
the vcu worked perfectly its the traction control that I was having problems with
The 2000 onwards TC is slightly different in that it pulses the brakes faster. The earlier system should provide enough grip to maintain momentum on slippery surfaces. That's what the TC was designed to do.
Oh well fairy muff then my traction control is "working"!! lol roll on icy weather so I can try it out on that!! lol

Hippo's got a good vid on YouTube showing older gen cars with diff lock having trouble on an axel twister and TC cars getting over no problems...

The pulsed wheels look like they're spinning freely, but obviously they're not! The D2 at 3:20 is a good example.

There's another one over ere too: Freelander 1 v6 Electronic Traction Control Demo Up Hill On Snow And Ice - YouTube
The theory of traction control is just that. To control traction. Spinning wheels sap all the power so applying the brake to a spinning wheel will allow the wheels with grip to have the power available in the hope it allows you to move. Naturally the system can fail if there's total loss of grip on all 4 wheels (or it's bellied out with not enough grip to overcome the fact yer stuck) and you have to appreciate it's a backup device which is helpful to have, a bit like a fire extinguisher, but not completely fool proof. The system is clever enough to vary the amount of braking to each wheel. Newer vehicles like the Disco 4 and Freelander 2 can pulse the wheels quicker than our Freelander 1's. The system monitors the speed of each wheel and pulse brakes them if they spin or turn faster than the others (beyond a set limit). Yer brakes need to work and yer need tyres with tread too.
