Just the 1 pair and it drove out like it hadnt even been stuck.

Bahahaha nobody wants to get snapped bogged.

Driving yourself out voids all embarrassment though!

I've had a couple of similar issues, the most noteworthy on Fraser Is. It had been raining and I was running 285/18s on GOE wheels at 16 - 18 psi. I basically went back to high range and I think I 'switched' everything off. DSC was definitely off though.


I was going along on a very slight incline and came to one of those erosion control berms so I popped the throttle to ride over it. Absolutely nothing happened ..... not a slow build and then whoosh like some OPs report at roundabouts .... absolutely no change in throttle. Even when pressing welly to the floor, there was no noticeable increase in revs.


It's happened a few times now but never in Low-Range.


Don't know what's behind it.

I have noticed it as well,as an example,mine did it on occasions during a Simpson desert crossing.

In high range on the flat,going slow,say around 45k/hr,then going slightly uphill,then back off as you hit a set of ruts at the base,or about a quarter of the way up a dune,over the ruts,foot down,nothing happens,no go at all.

I have shot up dunes,at speed on beaches,etc and never noticed it happen.Only noticed it at slower speeds,say under 50k's/hr.

In low range it never seems to happen.

As Celtoid has said,what is the reasoning as to why they do this?The vehicle is obviously designed this way for what ever reason.

I have no experience with this yet, so it is good reading about this stuff. Based on what Gordon said in his previous post, I'm guessing in high range and therefore presuming at higher speeds, Landrover won't let the driver have control and therefore re-instate DSC automatically without any indication. So it sounds like DSC is never actually able to be completely disabled as such, just selected off until the vehicle decides it needs it again, apparently more so in high range.
