But why risk overfilling when 5 litres will last for ages?

Don’t LR say that one litre should last about 500 miles. So 5 litres would be 2500 miles. That is possibly only a couple of months before needing refilled again?

I maybe just need to do some trial and error. Hopefully less error.
And fill up just a little and see how it lasts etc.

My tank implies it’s got 1056 miles left. Technically that should be about 2 litres.
If it’s a 14 litre tank, then I should easily be able to get 10 litres in.

Some testing needed me thinks.

If I remember correctly mine used about 1 litre every thousand miles

Exactly my thinking too.

No it just overflows lol and make a mess. If the warning message is on 10ltrs will be fine. Did mine the other week.

Not good advice at all, a dealer apprentice once overfilled our older MY16 because he didn't know how much to put in, that vintage of evoque doesn't tell you how many litres are left or how many to put in only miles left and as the OP says how do you work it out, I guess its just experience but we always entrusted the dealer so any 'incorrect quality diesel exhaust fluid' warnings were their problem not mine. The latest evoque as can be seen from DKZs screenshot actually tells you what you need to know

What we do know is is its a 14L tank, you can buy 10L reletively cheaply from a petrol station forecourt, the top up warning on the dash gives you roughly 1400 miles notice before it runs out, what we don't know is in the older model evoque is how many litres left for those 1400 miles but using DKZs screenshot it suggests at 1500 miles to empty he still has 5L and its asking to top up with 2gallons which is by my simple maths about 9L so it wouldn't be a good idea to put in 10L the moment the warning appeared, perhaps leave it till 1000 or 800 miles and put in 10L

As its so important not to overfill its piss poor that there is no gauge to inform of quantities remaining/required.

How do the dealerships know how much to add without over filling?

When ours throws the 1500 mile warning I buy a 10lt can and put half in and the other half in my van!

 

[chanlon1]

What's the definition of "overfilling" though?
Is it when physically no more can go in, and it actually flows out the end of the pipe, or can you overfill without even seeing the liquid near the top?

 

[Doink]

Overfilling is when you submerge to ultrasonic sensor, well before any comes out the filler neck. The dealer in question in our experience got the apprentice to fill it, as a rule if we're paying 29.99 to top it up then we ran it down to 100 miles so as to get our monies worth, this time the lad checked how many miles we had and then asked my Mrs how much 'SHE' wanted in, she said you tell me your the mechanics, well he proceeded to overfill it and cause no end of problems

From memory we always used to get it and it read 4800 miles to empty but how much they put in I don't know, perhaps they didn't want by risk overfilling it, shame on this occasion the apprentice wasn't thinking, my advice is unless you can reel off a 1000 miles in 2 days like Maffy then leave it till 500 miles and put 10L in, no worries of overfilling then

There is a sensor in there that knows when it gets low. How else would the warning message get triggered?
And the tech people will get the same reading from the sensor saying what % the tank is at. As mentioned before, I can monitor mine with a custom app I use and that dial is moving as I go around corners or up & down inclines.
Any tech with a doctorate behind his name would be able to tell you that 15% left in a 14 litre tank will require no more than 11.9 litres to fill. Give or take a margin not to overfill. The doctorate part is where you convert the litres to gallons for the sake of the invoice to the customer. 😜
Was it clever from JLR not to avail this to their customers and rather have a warning comes up so you can panic and go to your friendly JLR to fill up for you (at a price no less), I must say yes to that.

What is the app and OBD reader you are using to get this information?

 

[Straydog]

If you overfill then the float sensor apparently can't get a reading.

Sorry but I referred to a float sensor when the AdBlue tank actually uses a sonic sensor (a float sensor would be adversely affected by the AdBlue solution).

I use my OBD2 from my motorbike - it is called UniCarScan. The app I use is called Car Scanner.
Most reputable OBD2 scanners should work, I am not talking about knock-off Chinese ones from Fleabay.

I got a decent reader off Amazon which reads a lot of data via the Car Scanner app, however the Reagent graph is always at zero. Not sure if I need pony up and pay for the full version in order to get the data?

I still need to fix the Ox Catalyst monitor dial, but this is my goto screen.
Just do it if this is your thing. There is so much more you can get from it.

Thanks. In your settings, what connection profile are you using?
I couldn’t find any specific Evoque one, just

The standard advice for pre-MY20 cars (with filler under bonnet) is wait until you get the warning then put 10 litres in. That way you won't overfill it and bu**er the sensor. MY20 and later, with the filler by the fuel cap, the car tells you how much to put in, although it's best to wait until nearly empty and then put in 10l.

The warning being the first time it says DEF required in 1500 miles?
Or once it gets to zero, is there another "warning" you are referring to?
thanks

Try it and let us know! Joking aside why are you even asking, your given 1500miles notice, for us that's like 3 months of using the car daily maybe 50miles a day, there's absolutely no need to run out.

In ref to Paster Master at 1500miles there's somewhere around 5L left so it's a bit tight to be putting 10L in IMO, unless your going to travel a 1000miles in half a day why not just wait till the counter reads 1000miles and then put 10L in, it'd surely fit in then, no need to top up the moment the warning appears, there's plenty of time

 

[chanlon1]

why are you even asking

why am I asking?
So that I don't overfill, or only put a small quantity in and have to top up again.

I think I will just put a small amount in and try to work out how much the car consumes and go from there.

 

[Doink]

I get that but ive already given a detailed response, for the avoidance of doubt I'll say it again, it's a 14L tank, at the 1500mile warning you roughly have 5L left so putting in 10L at the first sight if the warning risks overfilling it so wait till 1000miles or 800miles and then put 10L in, or do what we do and run it down to 100miles only we then go to the dealer, you on the other hand can safely put in 10L, yes it won't be brimmed but it'll give you a few thousand miles

Thank you.
Appreciate the perseverance with me....I'm new to diesels, JLR and Adblue.........
