It does have a turbo lag I am afraid, my boss has one and I test drove two and they all had a turbo lag 
I am sorry, but I am not trying to rattle your cage here. I had a 530d E60 and the turbo lag urged me to sell in within 1 month of ownership. I then test drove 535d and the turbolag is admitedly much much less - but IT IS there.
My SA at Cooper BMW told me that the smaller turbo cured the turbo lag issue to a great extent but did not eliminate it and that is understandable as ANY turbo in the world will need a fraction of a second to respond to the signal from the throtle?

There really is no noticable turbo lag with this car.

What I was trying to understand was how you were trying to engage kick-down, if you weren't kicking down the accelerator ("gas" pedal)...

I have owned three e60s, 525d,530d and now this mother.
I have experienced the normal turbo lag in the single turbo cars, and have excepted this as a normal feature of the diesel engine.
But this is a real pain, it is not turbo lag, the 535d is almost free of that, it appears to be a software issue that delays gear changing in the D mode. It is very bad on a rolling start (i.e junction) but it also appears in town driving.
I have spoke to the BMW techs, they say its a problem know to them it across the range (Diesel).
Maybe the facelift gearbox will be better, but after 10 BMW's I have found all with some over looked design, the only BMW I owned with no problems is my wifes X3 3.0 SPORT.
I am thinking of a DMS upgrade, as my understanding is it removes this problem, but it also removes my warranty and I AM SURE I WILL NEED THAT!

My take on this is that you are maybe confusing the 535d's habit of starting off in 2nd gear and then deciding to change into 1st just as you set off leaving you pretty much stranded, rather than real turbo lag?

Hmmm... surely you can EASILY get 400 miles on a tankful without this palaver (and 800 miles is impossible on a tankful in a 535d - at least it is on mine).

The most on a run I have ever got was 42mpg on a 487 mile journey from Colmar to Calais....total max miles reached 678. So that would mean a re-fill at 600ish miles when the light comes on. 800 miles would be well over 50mpg and thats IMPOSSIBLE on a 535d.
I know an E60 does do slightly better MPG than an e61 like mine, but my old man and I drove the same route in convoy recently and the difference was minimal.
Normal 70-90mph Motorway run is about 35mpg in a 535d.
Where do you live? Must be no traffic !!?

OK about the turbo lag debate: It is a rule than EVERY turboed engine suffers more or less from turbo lag. Petrol, diesel, sequential, parallel turbos it doesn't matter. Yes the sequential TT set-up on the 535d makes it almost turbo lag free, but ALMOST! If you do some test with the throttle response/engine (turbo) delivery you'll see that there is some turbo lag left. Even though it's true that the small turbo in the 535d is spooled up a bit even from idle, that doesn't mean it's spot on with the delivery at every throttle input. To be spot on, in theory it would have to be spooled up at maximum or very high speeds and that would be almost impossible in practice. It would probably need a bov just to blow into the atmosphere the extra boost not needed in some times.
In conclusion i'm sure that no turbo car (even the 997 turbo) has the response of a NA engine.

I don't think anyone suggested that they could get 800 miles range

I think you'll find they did...just read the quote from the top of my post.
