Thread: Disabling ABS while 4wdriving in a 96 Discovery TDI?

Yes - while I certainly accept that many people claim that TC retards them in sand etc, when you understand how it works (retarding the wheel that does not have traction and transferring drive it to the wheel that does have traction) it is hard to understand how TC would retard momentum.

I have had two cars with TC an FL1 and the RRS and in my experience neither retards momentum when TC activates - in fact the opposite.

With a modern vehicle like the RRS I would say that it is Direction Stability Control (DSC) kicking in rather than TC and causing retardation but many people who say TC retards them are in older TC vehicles that do not have DSC so maybe early and slow to respond TC systems did cause issue.

However my FL1 was the first landie to have full 4 channel TC, and no DSC and it never had issues.

Yep, this is also my experience.

Once you deflate your tyres and choose the right gear + momentum, it is quite hard to get the TC to activate.
