    I'm with Terry.....sink the welly every now and again to let the transmission know what it's connected to....

    In affect, dropping into sports mode at each busy intersection/roundabout probably achieves a similar thing.

    My car was just recently serviced but flipping the shifter has become so second nature to me, I'd have to try not to...just to see how it drives lately. I'll give it a go.

    I owned the RRS MY2007 2.7 and now the D4 MY2012 3lt. Both have the same issue. The only way I have found to get around it is, as already suggested, keep the revs up by down shifting as you approach the stop. I was always under the impression this was turbo lag?

    Hi Graeme, does that mean you do left foot braking with the right foot slightly on the accelerator?

    LR have commented stating it shifts down slower to increase fuel efficiency and smooth driving. I see it as a pain cause I drive a Vito everyday and it has good engine braking and assistance from the auto when slowing down, and is ready to go when ever needed. Love the smooth driving but sometimes you just want it to move a little more quickly.

    Technically it can't be turbo lag in the 3.0l, as the first turbo produces boost right off idle....supposedly

    No, its usually because I do most of the braking early and allow the vehicle to coast the last bit into the intersection or roundabout so can hover between the accelerator and brake.

    I suspect there's more exhaust pressure for the turbo at idle than at a few revs higher on over-run with a closed throttle and no fuel to combust. That boost is within 500ms of the throttle being opened from idle rather than at idle or on over-run.

    I found that my 2.7 litre LR3 had the lag but have no such issue with my 3 litre RR Sport which has the dual turbos. LR claim 500NM of 600NM of torque available in less than half a second from opening the throttle and mine behaves as per LR specification. I could not believe the difference between the 2.7 litre single turbo engine (very slow pickup) and the 3 litre twin turbo (virtually instantaneous).
