Fuel Gauge

[IJD]

Anyone have an issue with the D4 fuel gauge accuracy, the tank capacity stated is 82L, when on empty I can only get about 70-5 litres onto it. I am about to start towing a caravan so I am not sure if I will need to carry additional fuel.

I would get 78L in on average from empty, prior to fitting the long range tank, now get 170=D. I'd be looking into the gravity fed 50L tank someone added to where the 3rd row seats and foot well live. Great alternative to adding 300kg to the rear with a LR tank and RWC if you're towing a caravan. IMO 82L is at least 40L too little for touring.

That's normal and one of the most common discussion points in here.
There's a reserve capacity to prevent running the system dry.

As Scott says, which is a feature of pretty much every car. They leave what typically amounts to around 80-100km of fuel after reading 0 km to go.

Maybe petrol's are different but the gauge on my son's V8 D3 is much better than the D4 and allows a decent range because you can use the whole tank. It's also the same on my TDV6 L405. As well as using much less fuel than my D4 the gauge is accurate and you don't seem get a massive reserve that is unusable.

Maybe the difference is that the 85l in the L405 is actually useable and there is a reserve volume on top of that or that the D4 useable volume is not the actual useable volume. Either way, I need the long range tank on the D4 but the L405 is fine without one, despite the specs saying that both have the same sized tank. I've never managed to get even 70l into the D4 tank at zero km to go and below empty.

Unfortunately I've just thrown out a great wad of fuel receipts from the glove box,, but I would normally run to empty, at which point the car tells me I have anywhere between 50-80 klms to go. It has run down to about 35-ish "to go", at which point the screen says it will look for the nearest fuel station .
It's never gone into any sort of limp mode that I can tell of, or shutting/slowing down.

But alas, I have a gravity fed tank as well, so its been a while since I've filled right up to tell how much I'm actually using, but there were a few full fills in the receipts,, so sorry, but I can't help with those figures.

I would say that if you're banking on that last 10 or so litres, then best you take a jerry can.

No good being stuck on the side of the road explaining to the wife that you did the calculation but didn't account for the head wind, or what ever, if you're cutting it fine have backup.

I would like an auxiliary tank of 40ltrs to fit in the spare well instead of the usual 100ltr or so tank.

I towed a caravan for 6 months. Took a 20L Jerry can and only used it 3 times. Filled up when we stopped for a coffee. The most I ever put in was 65L. I agree the gauge is wrong but so it is on every vehicle I have owned.

That's not the point. Because of the gauge you can only use about 55 to 60l because it shows empty too early and you don't want to use the last 10l which is actually 20 or more litres and fill up. It would be good if it was like the L405 where there is an actually useable 80 litres or so until the gauge reaches empty and there is still a reserve left. The D4 says useable 82l but its not useable, which is the main complaint.

On the L405, half full means you put in 40l, quarter full means you put in 60l and empty means you put in a bit under 80l, which effectively gives you a much greater range because you know exactly what is going on. The fuel range is also pretty accurate, unlike the D4.
