No CDL in sand?

While my disco does not have ETC - my Freelander does.

No real dissadvantage Gazzz and definitely an advantage "on road", but I have heard that when used in sand or extreme conditions the ETC can easily over heat. Personel preference, but I prefer to only have the CDL engaged when doing any off road as I like to know exactly what the car is doing as a result of my input. I hate the fact that I can press the accelerator and some electrics will make another decision without even consulting me first!! Many of you might say whay did you buy a car with so much elecrtics, well it is a comfort thing and on road I value these electrics greatly. It is simply off road I like the basic approach.

Sounds like some car park you have at work to get your disco stuck!!

Thanks for the info - I had heard that with ETC it will cut in as soon as the wheel slips but in reality the wheel still is providing some forward thrust until it completely slips - the TC stops this so instead of one and a half wheels driving when the ETC cuts in there is only one wheel driving - the other one is stopped providing drag. Clearly when one wheel looses all traction then ETC is helpful - a switch would be nice so that can beswitched off until needed or in real slop. Maybe a ETC system that cuts in much later - when slipping wheel is really starting to spin but there is still momentum might also be better.

Car park was soft dirt (with inpeded rocks) and the area closest to work was highly eroded with 2' deep ruts. No one will park in the area but 4wd will - front wheel fell into rut and transfer case caught on impeded rock - opposite wheels slipping hung up - at knock off time - embarrassing - had to be pushed out - real embassing - especially when the RAV 4 parked next to me just drove out

It should be clearly understood that in a situation with one front and one rear wheel off the ground, a CDL on it's own WILL NOT provide you with drive to the ground. Additional traction aids are needed to get power to ground, such as locking front / rear diffs, limited slip diffs or traction control systems.

It would appear that many D2 drivers make the mistake of driving their D2 like a normal 4x4 and back off the power when forward momentum is lost, then bemoan the deficiencies of traction control when a simple obstacle stops them.

Without going into a long winded explaination of how the D2 TC system works, to get the most from it don't drive it like a Nanna. Keep up steady power, or even feed it a little more and the TC will do it's thing.
