I think it was in this thread (im not going back through it!!!) that a video was posted showing a Deefer struggling to get up an axle twister on a modest climb...with Disco's doing it relatively easily. I and others made the comment that the CDL did not appear to be engaged...
Here is a video posted in the General section by a kind contributor, that shows how the TD5 traction control works (with CDL engaged...).

There were uphill axle twisters in that worse than the video earlier in this thread that the Deefer eats up. Its a better representation of what a Defender can do and its impressive. Not posting this up to start fights, just so that readers can see the true abilities of this vehicle.
Cheers
