D3 TDV6 fuel economy

[sinistr]

Hi all, I did a search but perhaps being on the phone -search yielded mill finds so I'm posting.

Got the D3 3 weeks ago, gave it a full fill up, I've so far done 750km and the trip computer is showing just over 200miles still to empty (330km).
Mainly city driving with about 150km of freeway - If everything is correct and the trip computer is not cheating me I should get around 1100km from the tank which would mean fuel consumption of 7-8l/100km!!!

If that's going to be the case it's absolutely amazing!!!! 2.5 ton truck using that amount of fuel (diesel) mainly city runs is just unreal in my opinion..

I'll keep you posted :)

Cheers mike

Ummm nope, something is lying, unless you have a long range tank.
There is no way the D3 will get that fuel,economy on 82L

Dreaming never hurts!

[101RRS]

The trip computer system is about 10% optimistic - so displayed fuel consumption 10% better than it is and displayed distance to go is 10% further than you will actually go.

On fill after a sedate country run I have often had 1200km distance to go showing but I rarely have got more than 1000km - that is in a RRS that is lighter, more aerodynamic but faster and more sporty than a D3 box on wheels.

Canaussie: you could be right! Long range tank could have been fitted - the car is an S with airbag suspension/terrain response and the guy who owned it and 2nd user did country kms... Even been in Tasmania from WA so it's possible he optioned it with another tank.

The last fill I did was 60odd liters and that was at 1/4 tank - I'll keep going for another 100-200kms and then fill it up :)

[sinistr]

Thanks Garry: what's got me surprised is the economy is on the up, this morning I had 190 miles to go and now I've got 220 miles to go..

Trip meter could be out but I expected the gauge to fall quicker than it has from half way anyway.

It will be obvious - is there a tank where the spare wheel should be under the rear - and if there is, there should be a spare wheel carrier on the back:).

What sort of l/100km is showing on the message centre and do you reset it with each fill? Also you keep on mentioning "miles" and not "km" so is the message centre set up for miles or Kms.

Garry

[TerryO]

Do you have a rear wheel carrier? If not the chances are you only have a standard tank or no spare wheel. ...:eek:

A long range tank is a expensive mod so chances are the person selling you your D3 would have been keen to point this out as it adds value to the secondhand price.

By the way fuel gauges on D3's can and do stuff up so be careful that you don't end up stranded somewhere with it indicating you still have 1/4 of a tank.

If the gauge starts to go up once it gets to around 1/4 tank instead of down then your gauge is stuffed.

[sinistr]

Garry: spare wheel is where the spare should be - so unless it's a larger stock tank.. There is no other tank fitted - no wheel carrier.

Computer is showing 10.5 at the moment (10.5l/100km). I'm quoting miles because the rest of the trip computer is in miles - need to visit the dealer to have it reset.

[sinistr]

TerryO: good point, I'll fill it up tomorrow just incase then and check. :) if again I get 60 odd liters it will give us an idea.. Last time it was 1/4 and had 60l - now 1/4 as well.

[101RRS]

Garry: spare wheel is where the spare should be - so unless it's a larger stock tank.. There is no other tank fitted - no wheel carrier.

There is no larger stock tank.

Can't you change to miles through the settings button on the end of the indicator stalk.

So if the message centre is showing 10.5l/100 your real consumption will be 11 to 12.5 l/100km.

Garry

[sinistr]

Doesn't allow me to change the miles to km... It resets the trip computer. Tried all the different ways I've found on the Internet - just taking the terminals off is left.

[RickO]

X2 to Garry's post below.

On a recent drive to & back between Melbourne and Brisbane, my actual fuel usage was on average 1.4 L/100km over the quoted figure.

Cheers, RickO

[sinistr]

It will certainly be interesting to see the fuel consumption... I just did another reset on the computer and strangely enough the range is now 90 miles not 200.. Beats me.. Maybe something hanged on the trip computer.

Anyway.. I'll fill it up tomorrow, see what I get :) I still think it should be pretty good! I think it will be sub 10.

Cheers Mike

Do you have a handbook?:( I don't know if there's much difference between the D3 and D4 re. message centres ... a mate's D4 requires you to get into the so-called "interactive" mode which you navigate with the steering wheel buttons some how, then scroll to vehicle information...and change from imperial to metric ... :angel:

[Rich84]

I've been able to get close to 1100 with majority highway driving @ 110km/h. As Garry said, that was in an RRS though which are slightly lighter and more aerodynamic.

Normally get about 820-850km to a tank, 30% highway driving, 30% city, 40% country driving.

Mine is the S model so I only have the cruise control buttons on the steering wheel, everything else is done through the 'i' on the light stalk but doesn't let me change any settings even if I hold it for a certain period of time etc.. Just resets the whole lot of data. :(

Mike the distanced to go does not use the average figure shown on the display - it uses an other formula that is supposed to reflect more recent usage rather than average usage since last fill or reset - don't ask me what that formula is though. If I have been driving in high fuel usage conditions and then refill, distance to empty on refill has been as low at 500km but as I start driving on the new tank but very sedately, distance to empty will slowly increase. If you monitor distance to empty closely you will often notice it going up rather than down as you drive.

Yes you are correct - there are posts somewhere on here how to change the internal menu ie change miles to km, mpg to l/100km, time lights stay on, speed alarm etc.

On cars with radio controls on the steering wheel, pressing the i button on he stalk resets the display as you have on yours but when you scroll through the various functions i comes up which allows you into the sub menus and use the steering wheel controls (up and down (volume) and side to side (radio function)) to select and change settings.

My handbook does not cover the basic radio/dash display so I am not able to advise how to change it.

Cheers

[sinistr]

Garry, you could be onto something there - I did notice last night I had the little 'i' letter pop up which I don't remember noticing before but I didn't do anything further.. I'll give it a go again this afternoon and try see if I can reset.

Do you think the controls on the radio would work in a similar fashion as the ones on the steering wheel? I'm intrigued now :)

Thanks for the heads up!

The range keeps climbing atm.

I honestly cannot remember the process for your car but something that does come to mind is that when "i" comes up on the screen and you enter the menu, as you do not have the steering controls I think the radio does it but I really cannot remember.

I guess you do not have the handbook for the car as it should be there. You can always join Topix TOPIx - TOPIx (http://topix.landrover.jlrext.com/topix/i18n/index#) put in your VIN and look up the handbook for your vehicle.


Garry

[sinistr]

Garry, sorry I do have the handbook but the instructions specifically relate to the car with the extra wheel controls, very limited for the standard pack.

[sinistr]

First consumption check - 10.27/100km!

Trip computer was still showing 90 miles range but I took on 79l of diesel.

Garry: I'm stumped, I can't get the little 'i' to pop back up on the display... I did have it now it's gone. That could have been my chance to change the miles to km. I'll keep trying.. I'll look into the book and see what I can get.

[BobD]

10.27 is a bit different to your first post. That is only 770km from your 79l but it sounded like you were going to do a lot more than 750km based on your first post.

You are lucky you could use 79l. I have never managed to put more than 65l in my D4 main tank with 0km to go for a long time and below empty on the gauge. I rely more on my 110l long range tank to get a reasonable range but even then I rarely get more than 1400km using both tanks.

Bob

[101RRS]

I am surprised some other S owners have not come along to assist as I know there are a lot on here who do not have the radio controls on their steering wheel.

Tapping the i button (not holding it should cycle you through l/100km, trip, distance to go, time and "i". When you reach "i" hold it for 2 secs and you should enter the sub menu (your on your own then). Holding the "i" when on l/100km for more than 2 secs will reset the message centre.

Sorry Bob, you are right about my initial count.. I was thrown by it but after a reset it was showing 90 odd miles (~140km) to go. I was able to put in 79l and I still had the gauge 3-4mm off the empty line not to mention the light never came on.

I need to find our what's going on.

Thanks Garry for your help, I just tried and tried and couldn't get the 'i' to pop up but now that you said cycle through I'll try doing that. All the posts online suggest going to the dealer to have it reset from what I've been able to find out.. But if I can change mine it will be a bonus.

I'll report also on my next fuel run.

Ok.. Just tried cycling through and nothing happened to make the little 'i' pop up :( don't know how I got it yesterday.

[sinistr]

Bob

Bob: owners manual says the car has an 86l fuel tank. That would explain the gauge still showing some fuel and the extra range on the trip computer. So it's not the 80l tank we initially thought..

[jonesy63]

IIRC, on the D3 - you need to have the seat memory module (under drivers seat), in order to change certain settings.

You can add the stereo controls buttons to the base model steering wheel, but you still can't change settings until you get the seat memory module.
Cheers,
Rob

[sinistr]

Rob, that's fair enough. I don't have that.
I'd think tho the miles-km is something accessible?

I just don't know how I got the 'i' yesterday..

[WhiteD3]

I might of dreamt this but.........

I am sure that when I got my 2007 D3 V6 SE delivered I had to kick up a stink with the dealer because I couldn't display the same info as I was shown in the demo car. After a few visits to the service dept they did something that gave me what I wanted.

But maybe the S didn't come with some display options....

[Glynhouse]

If it is any help I have put 82 litres in mine and still had 50klms to go showing on the read out !
Try not to do that too often.

My average consumption - up and down the Kuranda range road - is around the 10-10.5 per/100, usually fill up between 650 - 750klms.
On the road no van it runs at around 7-8klms/100, van (3tonnes) pulls it back to 15-16/100

Given we live in a country which uses the metric system it should be a no brainer to have the cars display in that format.. I had the chance to try the change and I missed it when the 'i' came up... I'll try a hard reset today and see if that makes a difference.

[sinistr]

just did a hard reset and nothing has changed for the trip computer unfortunately. :(

My long range tank is also about 110 litres - it gravity feeds into the main tank so completely empties before we start using the main tank (D4, 2.7 litre TDV6).

On the way across to Tassie a few weeks ago, we left Kalgoorlie with full tanks, topped up in Norseman. Aim was to reach at least Ceduna without re-fuelling. When we got to Ceduna, still had plenty of fuel so kept going, and ended up reaching Port Augusta (1,668 km from Norseman) with still just on1/4 tank showing on gauge.

The back of the D4 was loaded (with seats down) and we had a reasonable amount on the roofrack. Had a reasonable tail wind all the way across which would have helped.

Total fuel for the entire trip (7 weeks away, Kalgoorlie to Hobart & return with a lot of touring around / camping / fishing based on actual fuel purchased and km's travelled (I don't even look at the litres/100km readout on the dash) averaged 10.2 litres per 100km - which I reckon is pretty good for a box shaped vehicle which would have weighed well in excess of 3 tonnes with all of the gear we had in / on it (and I'm not what you'd call a "slow" driver).

Had to put a new set of tyres on it when we got back to Kalgoorlie - but that would have happened anyway and I was glad to finally get rid of the original Continental's. Took the opportunity to also install the TPMS that I had previously purchased from Juddy on here at the same time. Now it's due for a service, so will have to book it in with Barbagallo's now that I'm back down in Perth at work. :D

Definitely a much more relaxed (and cheaper) trip than the last time we did it (in a Prado) and the time before that in the D2. ;)

Managed to get the 'i' on the computer- turning the DSC off.. But still can't do anything with it. :(

[101RRS]

Isn't that just a switch on the dash above the radio? I don't believe that DSC can be permanently turned off.

When in "i" did you try twiddling the radio knobs to see if that could move you through the menu?

Tried everything... And got nothing. All the buttons, reset everything again and again and no menu :(

I'm certain though, last time the i came up it was not because of DSC.

[4evershiva]

hi guys, my computer screen displays 14.4l/100km, I got the disco 3 SE petrol version. Initially when I did the drove from Sydney to Brisbane, it showed around 10.5l/100km. After city driving, it shows 14.4l/100kms. Just did my recent service. Is it something I need to be concerned about....

[theresanothersteve]

We have the 2007 S, albeit coil (not air) suspension.

There is no way to get into the computer on ours, what you see is what you get. The missus was disappointed because she wanted an outside temperature display...

Our other car, the Holden ute, does have all the whizz bangs but I still calculate fuel manually, actually an Excel spreadsheet. Most accurate way to do it and you can observe trends.

[101RRS]

It would seem that you got the "i" message for other reasons. In the higher level spec systems you can go into "i" via the stalk but also if there is an issues somewhere in the car's system "i" on the display will come up - for eg recently the washer bottle on my car was low and the "i" display came up and a few seconds later said washer bottle low - any issue - major or minor will maybe bring up the "i" display - maybe as simple as rear door unlatched while ignition is on.

Did you try the Disco3UK site - I am sure they will have your answers.

Garry: I have mate, I've looked on just about every forum out there and many people have thesame issue and some are able to fix it with a hard reset (didn't work for me) or go to a dealer.

The I came up and gave the message - dsc off and that was it. But a big yellow light is on anyway so it's a little bit redundant. Other messages display as well like doors open, bonnet or tailgate, lights on or going home lights etc... Some functions are there but not all.

I spoke with Kevin at Rovertech and he said its something he can try and change with down thing he connects, otherwise it's a display issue. I won't spend $$$ to get it fixed tho - it's a little bit annoying but I can live with it :)

About to do a second fill up this week - have 200km to go according to the trip computer (120 miles) and have done 650km on the trip meter.

Computer is showing average usage of 10.8l/100km so it will be interesting to see what my calculations come back with and what's showing incorrectly where. Not a biggie if its out by a little bit.

[sinistr]

11.26 on the run just before, since then 10.27 again (identical to the first run).

We've taken the car down south for a trip 1400km all up. (Denmark WA)
9.57l/100km on the way down and around the place, still need to check on the way back.
