Welcome Jon, you're just up the road from me 
I too have noticed a decrease in economy since the cold weather has set in which I've put down to the FBH getting a lot of use too

After some head-scratching , I came up with the conversion formula (reasonably accurate) and thought, in case not everyone knows it, I could put it in here, as a sidenote to this thread. The formula works both ways. Generally it is
270 / known => unknown
e.g.
270 / 30 mpg => 9 litres/100 kms
or
270 / 12 litres/100kms => 22.5mpg
Hope my arithmetic's ok!

Eric,
To join the MPG game (and lets face it, its the real measurement unlike this new fangled decimal stuff) just change your settings in the Settings Menu form ltr/km to MPG.

Anyway, the computer in my TDV6 HSE (auto) gets reset each tank full, but I can tell you through the summer the averages were normally 25.5-26.5 per tank and rarely dropped below 25. Highlight was 29.8 over a 1500 mile family holiday from busy Surrey to the glorious Highlands of Scotland via a few golf courses. My mate and his family following in his 2 litre Ford Galaxy couldn’t match it, he didn’t get as much kit on board, they had to thumb a lift off me coz they couldn’t get up rocky track (read gravel driveway) and he had to leave his back row of seats at home.
My normal journey is a fairly easy going 20 miles of low traffic A/B roads all the way to my office, but this week the average is sitting at a lowly 23.8 after 4 days and 200 miles on this current tank. I’m putting this down to the FBH which has been running every morning and most evenings this week.
So now I arrive back where I started because I found this forum whilst looking up ‘Cabin Pre-Heater’ on Google. I still recall the dealers response to my question, “Is a cabin pre-heater available as an option because I didn’t see anything on the website or the documentations LR sent me?†“Well Sir, cabin pre-heating is standard on this HSE.†He has a snotty gram on its way to him as we speak. My aim is some free service vouchers and an apology from my dealer whilst I wait for BN to sort out a fix because he seems to know what he talking about.
Future posts will be shorter… I promise.
Welcome Jon, I am merely relaying data from experts. I have also been the test bed for the remote system. When I bought my first D3, the ad on the LR web site definately stated pre-heater. I also wrote to my dealer to ensure it worked ex of vehicle running and they endorsed it. It did not, so I received a nice compensation package from both the dealer and LR, but I did not ask for it and would not have, they volunteered it.
However I decided to try to get the facts, which I have done, you know the rest. Fantastic vehicle and I am sure you will be impressed, enjoy.

Thanks for the welcome...
Another thought on the MPG decline since the weather has got cold. For sure the FBH doesn’t help, but also the tyre pressure will also be down. It all adds up. A lone Disco in the land of the Cayenne.

You are spot on there. The FBH will burn until the engine reaches a temperature that the car can sustain its own heating system at. In towns this could be 15 miles or more as LR's traditionally run cold when on tickover revs. That is another reason why the FBH was fitted.

I'm still at 16.6 MPG after 300 miles. Could it be because of the heater? How much does it take? By the way there's a great fuel consumption converter at http://www.convert-me.com/en/convert/fuel

adara, can't recall if your car is auto or manual. I believe it is auto, in which case it will be lower. You may also find that you will use oil for the first 6000K as it soaks into the engine.
Yes that is a good converter, I have marked it for the future.

Ours is averaging 16 now  but this is the first tank of only school and shopping runs, all around town.
So what is this FBH, what does it stand for and what does it do? Is it why we get exhaust from the front of the car and the feeling of getting gased when warming up.

Hello BN! Yes, it is an auto. Had the service check the car today, everything OK. They mentioned the oil consumption too. Said that if after 1000 miles consumption does not lower they will try a reset. Could this help?

Do they all use oil to begin with as I checked mine after 1000 miles and it had used none at all should I be concerned ?   Zermatt silver 06 reg.

FBH - Fuel Burning Heater
In reality this is automatic and helps the engine warm up (thus faster warm air into cabin) at temps of 8 degrees or below. Turns off when engine at preset temp.
Yes you will see the exhaust from the FBH coming form under the left side wing. Look behind the wheel and you will see the exhaust tube behind the plastic wheel arch cover next to the engine bay.

Mine uses hardly any oil... and racked up 30K miles now. So don't worry, I'm sure its getting into the engine

Hi, similarly to Jon I'm also a first timer. Getting back to fuel consumption I suppose with a vehicle weight the best part of 3 tonnes our expectations shouldn't be too high. I've had a D3 since the middle of September but do not cover that many miles, having only covered 700 in that time. Many journeys are short, country lanes, to the village, occasionally to the school etc but we still manage to average 26-28mpg, and 30+ if we get a half decent run along A roads. I'll be interested to see what we get on a longer journey, the first of which will be to Eastnor in December. Car hasn't been used for a few weeks so don't know how the FBH in the colder weather will effect the figures but I can see that we could be hit quite hard due to the short journeys.
However, considering the type of driving we do and and the few miles we have driven I've nothing to complain about. I drive a manual S by the way so this could easily tie in with the thought that the higher range models use more fuel.
