Thread: 2015 d4 fuel gauge.

Get used to it. I've found that when the Dist to Empty shows 0 km I have nearly 100 theoretical kilometres left. Somewhere in the workshop manual it explains the methodology behind it. Basically they don't want you to run it to empty so it cuts out for the first time when there's something like 4 litres left. You can then restart it and drive on. There is a second event after that.

"In the event that fuel is allowed to run too low, signals transmitted from the fuel level sensors initiate the fuel rundry strategy. The driver will be notified before the tank is run critically low on fuel. Although this is a simulated rundry
procedure, it provides the symptoms of the vehicle running out of fuel and the driver will perceive it as such. The engine will stop when there is approximately 4 liters (0.87 gallons) of fuel remaining in the fuel tank."

The most I've put in mine is ~72 litres with 20km to empty showing on the gauge.

There have been instances of dented tanks and faulty fuel gauge senders.No harm in getting it checked.

In mine (MY14), after filling the gauge stays reading full for up to 100km before moving down.

I haven't actually taken notice of km-to-go versus refill amount yet.

That sounds better! It's been like it from new. I would of thought 82.5 useable litres meant exactly that. Fuel below empty on the guage is not really useable? Makes for a poor range.
Thanks for the replies.

Mine runs more like Scotts.
You could carry a 10l jerrycan and test the km to empty.Its something I want to do,problem is almost all my trips involve a 165km trip to the city.Havent really had it at home with less than half a tank to test the factory low fuel warnings.

Can the distance to empty calculation be recalibrated with a diagnostic tool?

Or, even more useful, is there a display that can be set on a diagnostic tool for the litres of fuel remaining?

I miss having an actual dipstick to check oil (SD V6) and want to know accurate fuel levels too.

I reckon I would be pretty annoyed that I had to walk 10 or 20 km (and back) for fuel for a car "pretending that it was empty". Is it really that hard to bleed the fuel lines?

When they delivered mine,they warned about the almost out of fuel "feature".Once there is air in the system it will not self bleed unless the tank is at least half full I was told.

I have put 75 litres in mine ... although when that happens, I feel like calling Weights and measures - IMO fuel companies often cheat on quantities delivered. Which is theft.

But I wonder what the capacity of the Disco's tank really is?

The petrol vehicle has a larger tank - would LR have the extra cost of different tanks? Or are the tanks the same size, with the diesel tank having more reserve, and the software making you think its actually run out?

The diesel has 82.3 litres, the petrol 86.3 litres ... it seems they both have 86.3 litres, with 4 litres being held as a compulsory reserve. Pretty good engineering from the sound of it.
