D4 Fuel Tank Capacity

Your tank could be faulty,heard of something similar on here.

The max that I have ever put in mine is 76 litres.

That small tank is one of the very few downfalls of the vehicle.

So in reality the tank holds 75 litres useable, not 82.3 litres.

Is that spec for the diesel or petrol engine? Previously only the petrol engine had the greater usable fuel tank spec.

Landrover Australia have a downloadable specification sheet for Australian models which states the diesel fuel capacity is 82.3 litres useable. The owners manual states the same.


If they had stated it was an 82.3 litre tank and you could only use 75 litres that could be understandable but they put in the word "useable". Truth be told if the fuel tank capacity was listed as 75 litres useable I probably would not have purchased the thing. Might give it a bit more thought and go through consumer affairs to see where I stand.


Very disappointing really as so far the whole Land Rover experience has been pretty good. Now you start to think what else isn't correct.

I think the most I put in mine was about 78L but that was without hitting the first out-of-fuel condition so perhaps 82/83L is the maximum that can be used (early D4s had a stated 84L total capacity and that probably hasn't changed), but stating 82L "usable" is a fair stretch for normal conditions. Hopefully the lower realistic usable capacity will seem insignificant considering the benefits of the D4. I could get 950 kms from my TD5 D2's 95L tank on a particular round trip whereas the D4 wouldn't go the distance, but was a far better vehicle in almost every aspect. If you do much travelling away from civilisation then even 82L wouldn't be enough.

So if i get the IID Tool can i reset the low fuel warning to something decent. Even when i run it to zero km the most i have put in is about 68 Litres.

On that same question, by fixing it , does it make the fuel usage actually closer to reality (if fixing the speedo etc to correct and removing the error)

And following on from Graeme,if towing, for example a heavy van,the standard tank is pretty hopeless.

There after market long range tanks available..

I actually got 1100k's out of a tank of fuel in my D2a,on a long run.You could actually squeeze more than 95l in it.

I regularly managed 1250-1300 kms from my 99 TD5 D2 until a good MAF was fitted. However it ran so lean on light throttle that it had a dangerous dead spot.

The D4 low fuel warning can't be altered but the calculated fuel consumption can be adjusted using an appropriate diag tool. As for 68L, are you persisting in filling it right up, dribbling in another 8-10L after the first cut-off?

I've put 81 litres in the RRS a couple of times without the trip computer having quite hit zero. Something's gotta be NQR?

On one trip miscalculated distance to next town and distance to empty read zero 15 kilometres out of town. Made it to the next town without running out and still only took 69 litres. Contacted Land Rover and they had me take it to a dealer who put the diagnostic computer on and said all is OK.


So, to test it out I put a jerry can in the vehicle with 15 litres in it and ran it until, like the book states, it started misfiring to indicate running out is immanent. Drove about 5 kilometres to next servo and first clicked off at 58 litres but after several attempts squeezed in 60 litres neat.


So in reality the tank holds 75 litres useable, not 82.3 litres. Pretty disappointed in that to be honest, coming from owning Land Cruisers previously with their healthy capacity and one Touareg (90 litres capacity) I nearly didn't buy the Discovery due to such a small indicated tank. Now to find out it isn't even what they state I feel ripped off. My business partner was looking seriously at one too but he has now gone off it, what else have they exaggerated?


For the record, I sent another email to them saying I wasn't happy and they didn't even bother responding.

The distance to empty is a vairiable figure,based on calculations of the fuel its using and the amount left.
I was told when mine was delivered it has a first warning that the vehicle is out of fuel.The vehicle will "run out of fuel".It now has around 10l of fuel to go,it will re-start.I was advised fill immediately as it will take 40l of fuel in the tank to be able to prime should you run it out the second time..
If you carry 20L of fuel you should be able to see how far it actually goes before it hits the "You ingnored the fuel gauge,the red light and the distance to empty".Simply put the 20L in and fill up,I bet you get very close to the 82 useable.

The inaccurate fuel gauge and distance to empty readings do not really worry me, although it is still disappointing. They have both been around a while and plenty have them working pretty accurately, especially when you pay so much for the vehicle.


The owners handbook details this;


Vehicles with a diesel engine have a system that prevents the fuel tank from emptying completely. When the fuel reaches a minimum level, the system activates a reduced power mode, i.e., the engine does not run properly. The engine is also switched off, after travelling a further distance of approximately 1.6 km.
If the fuel gauge indicates a low fuel level, or the low fuel warning lamp illuminates, refuel the vehicle as soon as possible. See LOW FUEL WARNING (AMBER).
If the system protection function activates, the vehicle must be refuelled immediately. In this event, the vehicle should be carefully driven to the nearest place of safety, as soon as safety permits
A minimum of 4 L of fuel is required to restart the engine, then use the following procedure:

1. With the brake pedal pressed, press and hold the engine START/STOP button and crank the engine for 5 seconds.
2. Release the START/STOP button.
3. With the brake pedal pressed, press and release the START/STOP button to crank the engine. The engine should start within approximately 5 seconds.

Also Andrew, if you had fully read what I wrote, I did exactly as you suggested. Fuel can with 15 litres in it, ran it until it entered reduced power mode (like a small consistent misfire), added the 15 litres and straight to a service station (about five kilometres) where only an addition 60 litres could be added after several clicks. Total 75 litres. That is what I believe is the rip off.


I should have added, I reset the trip meter when the distance to empty read zero. It was another 88 kilometres until the reduced power mode activated. That isn't just a slight error of margin, it would be closer to 15% wrong. I suppose that is the difference between British and Indian standards and that of the Germans. Hopefully the next Touareg is larger inside, that was the only thing that stopped me buying another one.
