Fuel range messed up or is this by design?

Just wondering whether everyone else’s car does this. It’s a MY24 L460 D350 and it’s the first time I’ve run it this low. It’s currently showing 29 miles of range left and the fuel light hasn’t even come on yet.

I struggle to believe that it’s meant to do this as my previous L405 Range Rover would be showing the warning at around 55 miles.

Does any one else’s do this or is there something wrong with the range countdown on my car?

Cheers

maybe its calculated that range from previous runs, did you just have a hard motorway journey? .. ... - .- -.

Nah not particularly. It’s being driven the same way as all my previous cars with a mix or town and motorway driving at cruising speed. Definitely not being driven hard at all. Even the SVR I used to have would warn you at around 50 miles or range which is why I’m so confused. I’d understand if I was ragging it but I’m not.

I guess the way to test Stan's thought is to go into the Remote app, click on the most recent journey and see what MPG it says you were getting.

If its a really low, like 15MPG then as Stan says, it might still have nearly a couple of gallons (ie not enough to give you the alert).

If it says something around 30MPG+, you know for sure you have an issue.

Good luck!

Curious to know what the miles left will read tomorrow after the FF has had a nightful rest. ... - .- -.

I had to go out now and couldn’t be bothered to risk it. It dropped down to 15 miles remaining just inside the red zone with the light on. Filled it up to the first click and it took just over 77 litres.

The online manual says usable tank size is 80 litres. That don’t really make sense to me either. So the light only came on with 3 litres in tank remaining? Seems like it gave me no warning at all that there was pretty much nothing left.

Fuel level is mostly measured by a „swimming“ piece on an level arm.
Its position and how the arm is bent makes a lot of difference.

I had a new supercharged P525 in 2018 and it showed far less range than expected, then my garage opened the tank and bent the measurement gauge, that it was showing exact „reserve“ light once 15 Liters/100km left.

Maybe this can be done in the other direction on your car? RR Classic 1998-2005

Hoyboy, my warning light comes on around 50 miles.

If these diesels run out of fuel it’s allegedly very bad news for the engines.

I would investigate if I were you. Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits. Emissions Analytics worked with........etc etc

Hmm that’s interesting,

It might be caused by that then. For reference I filled it up to the top a couple of days ago and it showed a range of 567 miles remaining. The needle didn’t budge on the fuel gauge until it was showing 452 miles remaining. Literally didn’t move at all for the entire time. I think actually drove around 80 miles in real terms before it moved.

Seems like it likes to overestimate how much is in there. I’m gonna try run it low again and see what happens. Didn’t get a chance to do it this week.

Yeah you’re right Bill really don’t wanna run it too low in case it actually runs out. That fact yours shows 50 miles remaining when the light comes on confirms my suspicions. Out of interest what does your car’s long term average mpg say?

I’m gonna test it again a few more times to see if it keeps doing it and if does I’ll take it in to get it looked at. Still confused on whether it’s the computer messing up or the physical float (or whatever it is) in the tank.

I’m not sure what the long term average is for sure, but guess it’s around 33.

As I posted the other day , I had some clear Belgium/lux motorway driving around 60-70mph and had 39 mpg.

Normally above 80/90 mph in France it drops to 30, Any faster goes down to 27-28. No lower.

Short trips are different.

ALL of my diesels , the mpg has improved with age & this one after 2 years is no different, I am seeing an improvement. Easily spotted by the fictional range after filling up.

When new the range after filling twas around 525 mile range, now showing 575 . As per all of the other cars the first fifty drops off after 10-20 miles or so.

Frankly on 15000 miles per year the Mpg tween 27 and 33 probably costs £500.00 and is really incidental to the cost of owning a FFRR, that said the difference tween petrol and diesel is not only the capital cost , but mpg of 22 against 33 is £1200-1300, more importantly if the end of the world is nigh, I reackon I can always find or store diesel, unlike petrol. Adblue might be harder to find! Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits.
