    I accept that to be a fact, however if I sit completely stationary and nail it, I'll get a variety of outcomes ranging from instantaneous through to significant lag. So that has to be the box.

    I do need to test it again though, as it may have been sorted with the numerous software upgrades that have been updated since the car was released.

    I agree - it is gearbox not turbo lag - this is reinforced as the pause issue does not exist when you use Command Shift. If it was turbo lag the issue would then the pregnant pause would still occur. When the bit of turbo lag does show is when you are actually stopped and already in first gear and take off - the initial roll is a little slow until revs build up then full acceleration comes online - typical turbo lag.

    ...which is why I was curious about your experiences in different TC modes as these will 'tune' various elements of the systems.

    If it didn't happen in 'Sand' mode, with the g'box in auto, then it's going to be down to software more than a turbo thing.

    Haven't tried it in different TR modes - next time I go out I will see what happens - I assume there is no issue driving on the bitumen win sand mode.

    No problem at all but you should find the throttle a little more 'lively'...

    Well I drove about 100km around town yesterday and drove the first half in sand mode and the second switching back and forth - to be honest I could not detect any real difference except that when in sand mode it hung onto 5th gear a lot longer before changing into 6th. Still has the pause in Sand mode.

    However my engine is mapped and Drive is now quicker that Sport so that may also be the same with sand mode.

    If I have bought my car new - it would have spent most of its life at the dealers trying to get this pause fixed - then I suppose with Consumer Affairs trying to get it sorted. It really is not good enough and is dangerous.

    On a slightly different aspect part of the trip was to get some Castrol engine oil from the distributor but they only sell it in 20litre drums - good price but I don't want 20 litres at the moment so looks like I will continue to use a synthetic Nulon which is near enough.

    Why don't vehicle makers use oils that are commonly available (other than dealers) because most of the required oil that meets all specs rather than just some of the number are just not available in Aust. It seems near enough has to do.

    Whilst I agree it is sometimes a little annoying, I think you may be slightly overstating it. Once you know the car and drive to is capabilities it is not dangerous unless you drive it dangerously and it's not that big a deal. You do need to be aware of it though and sometimes you might need to wait for a slightly longer gap in the traffic before pulling out.

    The lag is nothing like the lag you used to get in an auto D1 300 TDI I had a manual one, but I had an auto as a loaner once and was shocked by the lag that used to have.

    Completely agree with Andrew, your view of it been dangerous suggests you are driving irresponsibly. As noted you are aware of this very minor delay but hold Land Rover responsible for the events that could occur because if it.


    Where is this world heading when we can't take responsibility for our own actions.

    Nonsense - and I am not the only person to have raised this as a safety issue both here in Aust and in the UK.

    When you wait for a break in the traffic and then go to pull out and it dribbles out at 5kph with nothing happening when my old lumbering 101 would have no trouble then it is dangerous - and I am not first to raise the issue.
