Driving a BMW and NOT doing any of the above? Is that even possible??
To the OP, that's real good MPG btw.
My 205TD does similar MPG, only weighs around 800kg or so, and is only 80hp, so less than half the power! It is about as high tech as a tractor tho, which means I can fix it with a hammer.

Driving like that is so much fun tho
and mandatory for all Bimmer drivers.My 225bhp beast can quite easily return 35-37mpg if driven normally, and its surprising how relaxing your journey compared to bombing it in the outside lane.
That said, i have never been happy with the MPG i have gotten in Diesels, i have never gotten the claimed figures, i guess i keep trying to drive them like Petrols.

How bad is it?
I'm now down to an average of 51.3mpg due to 80+mph indicated (legal on Irish roads guv) trip today with a very laden car (about 200kgs in the back). Thats over the last 500 miles, and the range is displaying 260miles after some spirited driving home from the motorway...

I will probably get slated for this but my Pug 307 2.0 XSI managed a sickly 28.1 Mpg over the past 2100 Miles.
The trip computer is accurate to +-0.5Mpg
Mind you i dont really care as i only do about 7,000 miles a year so the diffrence between 28.1 Mpg and 35 Mpg is only £178. (ignore tyre cost)

With regards to the lack of power below 2K RPM, I'd make sure you get the car serviced if it hasn't been. A new air-filter and some fuel additive made a difference for me.
I'd recommend you get some of this: http://www.edirectory.co.uk/pf/880/mia/d/millers+diesel+power+plus+sport+4+500ml/pid/5589699
Obviously shop around as they can be expensive. Essentially its just like running expensive fuel.
So, service, filter, fuel and then see if that lag is still around. If so, remap. I had my Punto JTD done. A sports map allowed power from 1 to 4K RPM. Power delivery was very smooth. Turbo certainly had to work harder. MPG certainly went up - this obviously meant maintaining the same driving style.

After driving the 530i most of the time our 530d always feels a bit lathargic below 2krpm, and it's fully serviced and low mileage.
Not sure whether my fat fryer's engine needs some more miles to losen up or something. It's ok on a gentle cruise - 49mpg @ 75/80mph down to Cornwall last week, but around town it's straight back down to 33mpg which is a joke.
A fair chunk of the economy advantage a Diesel has, is actually down to the fact there's no choke on a cold start.
Must say the fact there's zero power under 1800rpm is VERY annoying, quite a few times I've been stranded with no power trying to nip out in front of someone coming round an island or trying to nip out of a junction or whatever. It's nowhere near as flexible/driveable as a petrol engine.
Mine's on a 2 year lease but I might be able to offload it soon onto a colleague here and get a proper oil burner with a 3.0 engine and more pistons.
If I paid the £17,000 price tag for this car out of my own money I'd be considering suicide right now.

Am i wrong in saying that turbo lag is the lag on throttle response that you get at *any* engine speed in a turbocharged car, at least thats what ive always referred to as lag, not the engine speed at which the turbo's become effective.
The 335i for example gets around some of the lag by having 2 smaller turbo's which take less time to spool.
On my old (1985) RS Turbo, it would lose to a 1.3 escort below 2500 rpm, keep it around 3000rpm and it simply flew as soon as you hit the pedal, anything much below that and you had to literally count "one two" before anything happened!
Modern twin turbo's don't suffer this, which is as you say, due to the spool. (I think!)
Thats because the turbo was innaffective below that engine speed, thats not lag 
, lag is the delay from mashing the throttle to receiving boost, due to the big fat turbo having to spool every time. The 335i's turbo's i guess would be a fair bit smaller, and more efficient, thus being less laggy. They still feel laggy though, so turbo technology cant have come on that much

Comes down to that "Boost threshold" and "turbo lag" thing. Your right in what you say Jez but the terms tend to get so mixed up by people that "lag" is the term that tends to get used for both.
I dont get why people dont seem to be able to differentiate between them. I commented that i found the 335i fairly laggy, and was getting replies about the fact that it can make full boost at 1500rpm - thats not what i was meaning, i was meaning that at *any* engine speed, you get noticable lag :/
