Hi everyone I'm new the forum
I have just purchased a 2012 SD HSE Discovery 4 with 127000 kms on it, our previous car was a 200 series don't hold that against me! I'm guessing this issue may have risen before but I'm hoping for a fix to this issue as the car has 3 months warranty, the issue is the hesitation when slowing to a stop and than going to accelerate and it just dies is this normal? its quiet unnerving and dangerous. any help would be much appreciated.
An Italian tune up once in a while will help.

I had the same issue with mine when it was new. Possibly not as dramatic but caused me concern. This is my first turbo engine. Dealer said it was the delay until the turbo spun up from start so to speak. Noticed especially at first pulling into traffic when it would seem to decide if it would go. The other spot was an uphill intersection where I had to brake to a very slow speed to see if it was safe to go. In that spot I can use the gear override to be in a lower gear and that overcomes the issue. You do get used to it and adjust your driving and it's not such an issue. As the above post said using sports mode will help too and you can, as he said, alter the gearbox response by driving aggressively for a while as the gearbox will adjust to suit your driving style.

I agree with comments above (sports mode, driving style, manual downshift, etc) re reducing the lag.
But there is always some hesitation that you need to be aware of and consider when pulling into traffic.
I don't think it's turbo lag, it's programming to avoid wheel spin.
Jumping out into small gaps in traffic is not recommended in a 3t 4WD.
Cheers,

I think it’s a combination of the trans getting into the right gear and the ECU controller throttle holding back for the trans gear and then the turbo winding up. Sadly an electronic throttle isn’t as linear as a cable. I don’t notice it much anymore as I think you learn how to drive around it. Rolling on and off the throttle rather than big stabs improves things.

Exactly,it took me a while to teach SWMBO this.The Auto on ours will bang if you hit the throttle hard very occasionally after slowing down almost to a stop, as well,driving around this as well negates the problem.
Then i had it tuned,the lag then virtually disappeared.

Mine does it, 2016 D4 just out of warranty. Never did it before so suspect it's a gradual thing with something electronic and I've checked with the Gap Tool but there's no faults showing.
Looks like a job for an "expert".
And I won't be looking for one of them at the stealers.

That's an interesting observation Alan. I'm wondering if it is an early warning of a more serious issue, such as a build up of gunk or a small split or tear in the intake somewhere. It would appear that, as far as the vehicle's internal diagnostics are concerned, the episode is within accepted parameters so no error codes are triggered.
Has anyone experienced these episodes before needing to do any serious repairs? I'm thinking intake manifolds, EGR repairs etc.
