Adblue range on 2026 Berlingo

[Mjsmke]

I can't find the answer to this anywhere and any video i find is for an older model with the spanner button which i don't have.

I'm new to adblue and want to keep on top of it. Rather than waiting for the warning light to come on, is there a way to find an approximate range for my adblue tank?

I can see fuel consumption, fuel range etc but nothing for adblue.

Again, i don't have a spanner button, or any physical buttons around the display infront of the steering wheel.

Which engine does it have ?
Our 2016 1.6 hdi Cactus uses about 1 litre of adblue per 1000 miles, the 2019 1.5 hdi 308 uses about 1½ litres per 1000 miles. The handbooks for both give the adblue tank volume about 17 litres.

To top them up I do not wait for the low level warning but add it at servicing time once a year using the 10 litre containers to fill them but first add Wynns crystal clean and protect.

I wonder what prompts the injection of AdBlu? Probably the same as Eolys, the addition of more than a certain amount of fuel, 10L IIRC.
If that is the case, and it is going to be a wearying exercise to try, then filling up say ¼ tank each time to trigger it often may prompt a potentially sticky injector/pump to be revitalised.

I recently had a problem with my daughter's C3, defective pump. Let the garage do it as I am somewhat past being entertained by crawling around under cars. Came to £600 all told which was half of what I had expected, not pocket change though.
Actually Eolys come to think of it, but similar in function.
This was an independent garage but the owner is Citroen trained and plenty of experience, a decent and trustworthy bloke too.

I might be wrong but I would have thought the adblue is continually being injected in to the exhaust when the engine is running, unlike the eolys that is injected into the fuel tank at some point after filling up.

[myglaren]

More than likely.

Adblue is injected continuously when the engine-system reaches operating temperature. Eolis is injected only when it is doing regeneration. Adblue doesn't have a real liquid level gauge so you can't see exactly how much there is. There is some float inside that only reads three levels and it can only be read with the diagbox program .

[PaulC5]

Somethings to add, on our 308 it did not have a full adblue tank when new as it gave a low level 1500 mile warning on about 6500 miles so would have only used about 10 litres at most. After putting in 10 litres the warning went but there was room for more. About 3500 miles later I put in another 7 litres and it was full. It could be the car when new only had about 10 litres put in and not a full 17 litres. I also found the Peugeot official services do not include filling up the adblue so Citroen could be the same.

It's a 1.5 BluHdi. 2026 model.

I just want to know roughly how much range it has before setting off on a 4 day trip. I see the older models show an approximate range for adblue and service but can't see it on mine.

A few thoughts on AdBlue based on my 8 years with a 1.6 Picasso.

The estimate of 1l per 1000 miles seems about right. It does vary by vehicle and engione, my son's Transit uses at least double that.

The normal tank capacity is 17l but you never know how much is in there until you get the 1500 mile 'bong' warning.

When you top up it needs a fair bit to cancel the warniing, I think I recall reading 4.5l somewhere. Even then it can take a couple of re-starts before the warning goes away.

Unlike the early days of "blue Hdi" you can get adblue just about anywhere so no need to worry about running out away from home. It can be a bit expensive in some places so if you can plan to fill up at home it's better.

I used to buy 10l containers from screwfix, aldi, wherever.

When I got the car - preowned which is marketing speak for what those of us of a certain age called "used" - I had no idea what was in it so I ran it until the first 1500 mile warning, added 10l then waited several months for the next 1500 mile warning, that gave me an idea of usage and after that I just put 10l in every X miles or y months and never had a warning again.

You end up with the 10l containers, several over time. I noticed that some Tesco filling stations now have recycling crates but I used mine for outdoor container grown tomatos and small cucumbers. Cut 2 or 3 com of the bottom off, handsaw does it, and you have a pot base as a bonus. Take the cap off for drainage, turn upside down, fill with compost but as you fill bury the flexible spout in one corner, big end up, to make watering easy.

A geopolitocal aspect of adblue.

Its 30% urea, not a petrochemical but production is energy intensive. Thats why urea is now made in countries with spare gas & oil - Oman, China, Russia.... Most, 90%+, of the worlds urea is used in fertilizer. The rest in other things including adblue, and of course big trucks use gallons of the stuff. Look at the truck filling bit on motorway service areas, you see adblue pumps. Fertilizer prices have shot up, supply worries because we can't feed the population without nitrate fertilizers. China no longer exports urea products, Russia is Russia, and there's a big ship full of the stuff off the coast of Oman, wrong side of Hormuz. No need to panic buy, its not the sugar shortage of 1974 or the run on toilet rolls in 2020! But if I needed some soon I would get some in. If there is a supply crisis coming we'll probably run out of diesel before we run out of adblue but you do need both for a modern diesel engine to function.

... Eolis is injected only when it is doing regeneration.

I don't think so. I agree with PaulC5 and I'm sure it's injected into the fuel tank after putting at least 10l of diesel in. It's a measured amount which varies with what the fuel gauge reads before and after filling up.

Very early Eolys equipped vehicles had a magnetic operated switch on the fuel filler cap which simply dumped a certain amount into fuel tank regardless of how much fuel was put in.

I also found the Peugeot official services do not include filling up the adblue so Citroen could be the same.

Not my experience from some 8 or 9 years ago. They evacuated the Adblue tank and then put a measured amount of Adblue in. 10l or 17l I can't remember.

I was especially annoyed as I had just topped the tank up myself and specifically told them NOT to do anything with it.

I remember that, part of the standard Citroen service. I suspect it was to reassure sceptics who were being forced to blue hdi and were uncertain about the whole process. It didn't last for long, when every member of staff in the dealership had poured litres of urea onto their compost heaps what would they do with it next? Plus its wasteful as you say. But it does reinforce the fact that no-one, not even the dealer workshop, can tell how much adblue there is in the tank.

Next up was the 'bargain refill' from main dealerships - refill your adblue guv, only £xx. But it wasnt a top up, just 4.5l added in so it made it expensive adblue. Now we all do it ourselves - well I don't because we no longer have a diesel in the drive - just like you add any other consummables.
