AdBlue: What is it, and why don't more diesels use it? | Auto Expert John Cadogan 

I understand that Adblue got its name after the marketing disaster of the more honest and accurate Golden Showers Additive.

This just reminded me of the absolute pleasure I experienced the other day. Following a 70s bus/motorhome, running a 2 stroke Detroit Diesel. Not only were my ears blessed with that fabulous music they produce with their straight pipes, but I also got to enjoy the very different smell of purely burnt Diesel fuel, without any of this BS between combustion and release to the surroundings. Bliss!

As a diesel mechanic in the US i have a different slant on adblue or def fluid as we know it. The problem.... polution The solution as you mentioned of 66% de-ionized water and urea (a byproduct of petroleum) Dispenced in a plastic jug, placed in cardboard boxes stacked on wood pallets wrapped with plastic shrinkwrap. Placed in diesel trucks and distributed to every ass bleeding retail establishment from the hollars of Appalachia to the desert of Arizona and the Canadian tundra. Purchase the product and pour the contents in your tank then throw away the bottle, shrink-wrap and cardboard (upon which another truck will take to the landfill)... congratulations you have helped solve pollution!

Great informative video John. As an automotive tech of 35 years +. The changes to comply with Euro emissions standards have even confused me. I'm an Australian based automotive technician. Highly Bosch trained. The general automotive public wouldn't know there is a difference in exhaust after treatment. Dpf. Diesel particulate filter. Deals with the fine soot particles that are produced with normal combustion of the fuel . Due to the high energy density of diesel fuel and the low energy conversion . Incomplete combustion ends in the production of soot. So the Dpf was designed to trap and capture the fine soot particles which will pass through the upper airways of human lungs . As mentioned in your video that primarily captures them in a small furnace to be dealt with later. Such the term. "After treatment". SCR is selective catalyst reduction. The addition of urea in to the exhaust is to combine nox ( oxides of nitrogen) with a readily available source of nitrogen to scavenge the nox with nn2 to reduce nitrogen oxides to produce nitrogen dioxide. With the vehicle density of a population of Australia it is not an emissions regulation to meet 0.005 gas per km. Due to the square km to vehicle ratio. Manufacturers can not justify the small amount of vehicles sold here on Australia soil. That will aid to the total emissions goals of the company. This is the reasons why "adblue' isn't a major requirement on most vehicles. Certain manufacturers that want there vehicles here won't delete emissions equipment to allow that vehicle to be sold in this country. Due to the cost of retooling for a certain market. But it still asks the question of when the nox sensor is in the realm of $600 plus for one sensor. Why isn't it just not fitted and a software rewrite just implemented.

So if you burn recycled cooking oil and adblue... do you get the unmistakable odour of piss and chips 😕.

Great explanation! My Euro car uses one tank of Adblue (about 10 litres) for approximately 15,000 km. There are early indications of low Adblue. However,a friend of mine has a Euro campervan that uses almost as much Adblue as diesel! All things are not equal so the warning about being out in the bush with low Adblue is very valid.

Just changed the (fully clogged) DPF filter of my car by myself. I took the old one to the recycling center and throw it in a big container of metallic stuff. Do you guess where all those kilos of trapped ashes will go when they will press and triturate that metall stuff? Bingo! In the air. Pure genius.

My sister bought an Audi Q7 brand new which kept running out of AdBlue and stopping. Turned out the plastic container had a crack in it. It took four visits for Audi to figure out they had used a plastic tank that wasn't even as good as Tupperware.

A ten gallon spill of adblue covers a fair bit of workshop floor. It was all hands on deck to clear it up,an eye watering experience!

I like this guy. Basic common truth presented in a humorous way. Salut John. From South Africa.

The Adblue systems on PSA Europe vehicles had a clever system of using a plastic impellor on the Adblue pump, which is guaranteed to fail, leaving you with a £1000 bill for metal impellor pump, and a new tank as the pump is built-in! When the warning light comes on you had 1500 miles before engine "re-start" was blocked, if you didn't switch off it would keep running, as they cannot turn the engine off on a car doing 70mph on the motorway

Hi, John! Just stumbled on your channel, have subscribed. Your explanation of AdBlue, and Catalytic Converter, was just the best I’ve come across. 👍

Engineer's mantra. "If it ain't broke, fix it 'til it is."

John does make me laugh. The comment "The EU cuntries being the most advanced democracies in the world" almost induced an episode of urinary incontinence ...

You have to remember that engineers are subject to the whims of the bean counters, so what is actually best engineering wise is not always what makes it into the final product as cost quite often trumps good ideas. Then you also have the lawyers who determine if the business can get away with cutting corners to save more money, this was evident with the VW diesel scam even after the penalties they still made out like bandits.

I worked at a Company in Norway, that had a total world monopoly on Adblue, (which is a trademark for DEF. diesel exhaust fluid) heaters and quality sensors, also fuel level sensors for all commercial vehicles. Look at the fuel sensor and adblue installations on your Trucks, Tractors etc., they all look similar that's because they all came from the same place, (made in China). The process what DEF does is known as SCR (Selective catalytic reduction) converting Nox into N2 and H2O, DEF is only distilled water and urea but you can't make it yourself because there is the quality sensor in the installation and it's so finely tuned that you will never get the right mix, It is measured optically but they were trying to make a sensor that measured the quality ultrasonically, don't know if they got so far as left 6 six years when the Yanks bought the company and moved it out to low paying lands, the company who now has the monopoly is called TE Connectivity.

The problem with adblue is it tends to crystallise, had to have my tank replaced in January, Citroen paid £750 towards the cost of replacement - £1250. Most people don’t realise that adblue should be stored between 0-30C. Friends tank went again after replacement, now had it coded out.

Let's fix it by having the engineers actually spending time with those who will be using the product out in the actual world, instead of just sat in an office thinking they know what the customer wants!

yep; hired a Ford Everest from Melbourne to Perth last September, had to top up the AdBlue tank at Norseman. A real learning experience. ps: was not aware the engine would stop if the AdBlue tank was empty,. so glad I did fill it up when I did. Book said one tank would last 5000Km.

I haven’t checked recently but when I lived in Edithvale on the edge of Port Phillip Bay, it was possible to see a tinge of nitrogen dioxide on the horizon and the edges of the bay. It was the colour of black tea, cola drinks or bromine. This all goes away on a clear windy day.

My previous car was a Citroen C3 1.5 diesel from 2019 and it would warn you when you had 2400km of adblue left. Would have to be some serious roadtrip in the middle of absolutely nowhere for that to be a problem :D.

I got both DPF and AdBlue on my 2.0L diesel hatchback, and being a frenchie, the DPF uses a special aditive to lower the regen temperatures (Eolys 176).

Currently replacing the engine in a 2001 TD42 powered Patrol ute that the owner "cleaned out" with one litre of Add Blue. In the fuel tank.

Thank goodness for the diligent work done by our Federal Chamber of Automotive Industries. The other thing John, my Holden Ute takes offence at being referred to as a shitbox. It was built in 1982 anyway. It and I do not care what comes out of the exhaust except the sweet 253 note from its twin system. I will go back to walking before I use either adblue or an electric car. Jeff.

I can remember driving heavy B-Doubles for a major company and the shortage of Ad-blue in early 2022. I had to get Ad-blue from another of our companies depots (ours had run out) and it was an all in bun fight to get permission.......my depot boss had to have written permission from the other depot boss in a chain of emails that then had to filter down to guy in the workshop with the bowser key. Fleets were paying $4 per liter for the stuff.

Thanks for this John. I'd often wondered about ad blue but couldn't be arsed to look it up, anyway your explanation is much more entertaining than Google. My S class Merc. Uses it.

In europe, the Euro6 sprinkles the adblue even on idling. That cloggs up the DPF with the Urea stone. Also new 2023 hiluxes in farms go to the shops for DPF delete. Because the do the ReGen like in every 200kms and even when idling. For preventing to set a field in fire when harvesters do theyr job and you go to check the progress, chat with the operator and let the aircon work on a hot summer day. And the dpf starts burning with 600c and you are standing in a dry hay or crops field. Neighbor's 2016 hilux started to catch fire after driving in Peat moss

I drive Kenworths with both Euro 5 and Euro 6 engines. The Euro 5 only use AdBlue and not a lot per trip. Average about 20 litres a trip. The Euro 6 have a DPF and AdBlue. They use about 3 times as much AdBlue for an equivalent trip. Supposedly better fuel consumption because it runs dirty/efficient and gets cleaned up in the after treatment. Not sure if it saves 70 litres of fuel a trip but it uses a tank of AdBlue for a tank of fuel pretty much. A bit of a wow the first time I drove one. My trucks are towing 100 tonne roadtrains so with less full load running it would probably not be quite as severe

Our GWM Cannon has a DPF. It does automatic burns but if you dare interrupt a burn three times, it can and does go into limp mode and drop the power immediately. Weirdly enough, the owners handbook shows that overseas models have adblue, the filler a smaller nozzle beside the normal fuel filler. I wondered why they had a long rectangular fuel door and when you open it, you notice that the diesel filler set well over to one side. That’s why. Overseas the second filler would be beside it taking up the free space that’s there on our version.

Sending love from Canada dude!!!!! From the top of the globe to bottom! Love the content John.

Not sure how many AdBlue-cars you've driven, but here in Europe besides it being mandatory to prevent engine start when you out of AdBlue, a very early and generous warning system is also required, giving you the first warning that a refill is required 2400 km before the end, which should be plenty in all halfway civilised regions, including most places in Australia. It then gives subsequent warnings at every engine start, counting down remaining distance in 300 km increments, until, when you really get towards the end, it will say something like "5 engine starts remaining" until "One engine start remaining". If at that point, your one remaining trip does not take you to an AdBlue refill, it really and truly will refuse to start.

Great explanation but I'd have to take issue with a couple of things. As for "e" being the first key to fail on a computer just by virtue of it being most used, I find keys fail randomly depending where the crumbs fall on my laptop and even move around. Also, you seem to deride sorting out issues in the pub but I have to say that some of the World's best ideas have come from beerstorming sessions, I just can't remember what they were as I was pissed so fck yo, oh bgger, crmbs have got in the "" key now.

I learnt today that there is a Silverton in South Africa. The only other Silverton I knew of was an outback ghost town in NSW, 25 kms NW of Broken Hill.

A large car manufacturer did wind up putting a heat shield on their DPFs as a recall a few years ago due to grass fire situation. I'm not sure that OEM engineers get it right every time.

Your cutting mat is so clean. :)

Adblue is nice when it freezes and cracks the tank. Cheap too with Mercedes.

Hi sir. Thank you for explaining what everything does and the reasons why it does it , I know nothing about cars but I’m still interested in the aspects that are relevant to the owner . As my late father would often quote ( knowledge is king ) , admittedly at the age of 70 I might be leaving a bit late . But of course there is another saying that rebuffs the as well . Kind regards

I'm willing to put a reasonable sum on the fact not a single ad blue system will last 100 thou km..Outside of the workshop are 3 everests and 2 rangers (ones a bt actually) all picked up as cheap ins write off..I don't care and neither should you the motors fit quite nicely under the bonnet of any previous bs 4wd..for the princely sum of about 8 grand I can give you 200kw without a single bit of bs to deal with..new car b fuct...thanks for the support John the second hand market in this country is doing quite well...cheers.

There's a dpd/f disable mode on trucks when the pto is on, aimed at fire trucks to stop the fires starting from the 600°c the dpd/f's get to. Old mate hasn't worked on many vehicles if he thinks a full guard doesn't get full of grass... Plus it holds heat in at freeway speeds instead.

Before I watch, in the UK I think it's the difference between Euro 5 DPF and Euro 6 with add blue. And after watching, the difference is £12.50 per day to enter the ulez zone inside the M25 around London.

You are lucky to avoid the constant stream of ad blue warnings, EML and limp mode events caused by this technology. Along with blocked nozzles, control units and never ending software updates

I recall that during the covid disaster it was reported that Ad Blue was in such short supply there was a very real possibility that the road transport industry faced closure. Is Ad Blue produced in Australia or is it imported?

🤣STOP having so much fun making your vids John !! - its starting to show 😃

Out in rural areas, you have the issue of people stealing your AdBlue. That is quite literally taking the piss.

John, I have one of the first Euro 4 compliant NS Pajero’s that hit the country. I had nothing but problems with the DPF system for the first 3 years of its life and the dealer’s had no idea on how to fix it. I fixed the F@#ken thing though.😉 and you would probably guess how. I still have it now with no issues since.

The engineering behind all this stuff is fantastic. It's a great shame that diesel is falling out of favor when one considers how clean it can be if these systems are operating correctly. Countries like the UK do however need to put a little more regulation around modifications and emissions checks to make sure these systems do keep working through the life of the vehicle. At the moment one can broomstick the lot of it and get it all programmed out and still pass an MOT emissions check.. I suspect many are removed due to the huge costs when things go wrong.

I MADE IT DAD

Hi john, i just purchased the olight Baton 4 and the Perun 2. I just have to say the quality of the lights and the packaging is one of the best I've seen so far i can see why you endorse this company. I would encourage everyone to try this product. 👌 And my new isuzu truck does not have a DPF or Addblue 👌

My VW Touran warning light came on when the ECU estimated there was 1000 miles (1600km) of Adblue remaining. As far as I know, the system permits Adblue top ups at any time, not just when the warning light comes on.

To abide by Euro 5, there were 2 techniques that most manufacturers went with. Exhaust Gas Recirculation and Ad Blue. Euro 6 pretty much requires both to comply.

Thank-you for another informative technical video. I'm in the UK and I have a 2016 Skoda (so VW control logic) with a 2 litre diesel engine which uses AdBlue. A full tank is good for about 4500+ miles. The tank level is monitored and when the AdBlue range is down to 1500 miles, you get a nagging warning message every time you start the car. I understand that the warning becomes permanent when you get down to 500 miles but I've never run it that low. To run this out of AdBlue, you either need to be one of those who ignores warning messages or on a very long journey indeed. AdBlue is a minor chore but I'm one of those who ran a two-stroke bike for years so it really doesn't bother me. Only elephant trap is that when you've just filled up the AdBlue you need to switch on the ignition for 30+ seconds before starting the engine or the controller responsible doesn't update the AdBlue level (weird German logic if you ask me).

If you choose high egr use you can avoid nox, but more sooting, higher load on dpf, and oil detergent, intake carbon. If you treat nox with nh4, raise compression, reduce egr, better lkngevity? More complicated more ship to go wrong.

My favorite is the fuel extender you plug into the USB socket in your car.

Here in the UK, our diesels had DPF a decade or more back. AD blue is a later inclusion in cars and vans that was firstly introduced on HGV's and buses. EURO 6, I believe.

AdBlue is implemanted in euro6 ( either a , b, c...and now revision ap i believe) to get NOX down. Some euro6 engines have it some not as they comply. In some cases the same engine has different power output the lower power 2l turbo diesel under 150hp will get away without adblue but the same engine with higher power and over 150hp will require adblue to comply. And addblue will not be used at a rate that you will need to fill up like you do with diesel.... i did not realized in Australia a car could be brand new and not be euro6 equivalent emission standard...

John you are truly a font of knowledge, thankyou for sharing with us mere mortals.

If you are stuck in Dingo Piss Creek with no AdBlue, can you not just get the dingos to piss in your AdBlue tank instead of the creek?

Adblue treats NOx and Particulate filters filter particulates … seems pretty straight forward. As I understand it reducing particulates requires high combustion temperatures which means that more NOx is produced and most NOx compounds are lower energy than Carbon Dioxide, so carbon rich fuels like diesel produce more.

ABSOLUTE FANTASTIC info....nailed it John...BRAVO!!!

FYI: Ford Ranger Wildtrak X requires AdBlue as it’s Euro 6 compliant.

Very well explained JC, thanks. My current diesel powered vehicle is most likely the last I'll ever be driving so I may not get to enjoy the feeling of ever having artificially concocted pseudo "piss" in a tank onboard, (makes me think of an acoustic mobile shitoire` for some reason).

When euro 4 came out for trucks in Australia, I was working for Volvo trucks at the time, an engineer was explaining to us that the difference between egr and scr systems was that you can tune the engine lean or rich, rich gets more soot and treat it with a dpf, or run the engine lean and treat the exhaust with adblue, and for the early introduction of euro4 with trucks, most the smaller trucks could be egr and the bigger trucks needed to be scr. Probably got it all wrong. Guessing the emissions regs are so tight now that they probably need both?

Add blue works with the CAT not the DPF. This comment is not to John just other people who a watching who didn't pick that up.

I booked a VW diesel hire car in Rome. The dashboard said the car would not start if the adblue ran out. I had no idea what adblue was. Had to google it. Luckily, we returned the car with 50 kms left in the adblue tank. What a con. I was contemplating filling it with urine as didn't want to interrupt our driving tour.

Adblue can be coded out and is not tested for at MOT in the UK.

Hi John. Very informative video. Thank you. Correct me if I’m wrong here, but my understanding is the catalytic converters fitted to diesel engines, don’t actually deal with NOx at all. This is the job of the EGR system or the scr systems only. Only three way converters on petrol (non lean burn) engines can deal with NOx. Keep up the good work. I am envious of your deep engineering knowledge.

So in a pinch, being stuck on the Gun barrel Highway, with an empty Adblue tank, could I just piss in it to fool the ECU? Bushcraft, love it!

John, great video but when the first warning light for any car fitted with an AD Blue system flashes on the dashboard alerting the driver that it needs topping up there is at least a minimum of a 1000 miles that can still be driven before the ECU shuts the engine down and with many many cars now, like my DS7, it's 1500 miles, then another warning at 1000, then 800, then every 100 until it stops altogether and lets face it if you do let it get to zero then you probably don't have the IQ to be allowed a licence anyway. I know Aussie land is vast but even a 1000 mile warning of impending doom is far more than any driver needs to enable a top up.

AdBlue does have an expiration date and isn’t to be stored in direct sunlight as it often is in garage for courts . Urea breaks down with heat and uv .Always check the underside of the bottle. A lot of times it’s expired by some substantial time .

New Amarok (2023) uses Adblue in Europe same as Ranger (2023)

For anyone who hasn't experienced it, the fumes from a new London bus are reminiscent of what you would get if you stood outside from an extractor fan on an indoor swimming pool. Definitely a hint of chlorine or ammonia but far more fragrant than the sooty guff of 20 years ago. Literally no diesel smell at all.

Adblue's nothing like urine - there's no blood in it for starters. (You can scrape Euro 5 with about 170 bar peak cycle pressure, with adblue you can go nuts, so 210-220 or more with consummate efficiency gains as limited by the engine structure. It also tends not to cut in for up to an hour of engine start so your Euro6 engine will very likely be substantially dirtier than Euro5, especially on short trips. It's good technology for machines which run all day, but not for commuter cars.) Off highway seems to have a break point at 100kW below which machines don't need it, so there is a sweet spot for tractors at about 140hp

There are quite a few Euro 6 Diesels around without AdBlue. The later Subaru diesel is one example and the last of the Volvo 5cyl Diesels is another (I drive a 2015 XC70 D5 so can confirm its Euro 6 compliance and lack of AdBlue).

Thanks John, always wondered what that sign was about at the petrol station. I wonder if we could get those same regulators to stop Victorians from going "Eh, fuck it" and slamming into each other on straight freeways?

I absolutely enjoyed this video whilst I sat and stroked my beard. Thank you John.

Glad to see your handlers have cleaned you up a bit and got you to have a shave, was it with your rechargeable BATTERY shaver? that’s good they got you to have a wash, that should help to get rid of the slight odour of urine around you. How’s the weather down your way? Queensland doesn’t seem to be doing to well.

Our works Berlingo has a warning of about 3k that you need to refill the adblue. I always thought the adblue is a direct replacement for a egr, but how you explained this it seems to work in a better functional way then an egr. Egr's are fun to clean out, but a new adblue tank with all its funky electronics on a Peugeot, costs 4k to replace. Owch!

I own a euro 6 add blue diesel here in the UK and the dash gives you a 1500 mile warning before your add blue runs out so if you do run out its your own silly fault, the advantage with the add blue system is that the DPF is now incorportated within the add blue system and now mounted closer to nthe exhaust manifold in other words under the bonnet as opposed to a DPF being mounted under the car, these are getting stolen at a rate of Knots because they are easily accessable, just try getting you battery recipricating saw up past the front sub frame and close to the exhaust manifold to remove the add blue can and combined DPF its virtually impossible.

To drive to drunk had me there for a minute hahaha,love your work John.

Very informative. I've been told numerous times that Adblue was just an exhaust pollution masking agent.

What's so fantastically typical, is that at the vehicle registration office in Germany they will only issue up to a euro 4 stickers. Regardless if your car is euro 5 or 6.

I think you'll find a significant number of great innovations in engineering started in a front bar. *Started*. Because the following day people followed up.

The engine will not “stop” (a simple thought experiment might just illuminate just how dangerous this would be), rather it may not restart on a subsequent ignition cycle to the AdBlue tank depletion (or perhaps as John might put it…..’deplete-i-on’). Some models may just reduce power. Cheers.

Ive got a V6 2023 next gen Ford Everest they have a 18ltr Adblue tank that lasts around 15000kms so not worried about running out to much

Muy old 2014 Beemer 280D used the stuff. No big deal - I could easily go 10,000 miles/16.000 km on a tank of Adblue. That cost about $8.00 US at the time.

Yet another entertaining production John, thank you sir. The boffins at Subaru made my 2016 XV, (you may call it Crosstrek), a Euro 6 2.0D; without the need for adblue. But then they stopped making diesel engines, which is a shame, because I get awesome economy and torque from my wee XV. Which is especially useful when towing my old caravan Velma. So called because she used to get shacked up to Scooby-Doo my old Legacy. Many Cities in Scotland are becoming ULEZ next year, so will require Euro6 for Diesel and 4 for petrol ice's. But I like driving my old 300TDI defender most, and she does start the day by tossing a cup of oil into the atmosphere like a sacrifice to Satin, after which she produces very little smoke. She will run on almost whatever fuel you have to hand; paraffin, veg oil, whatever! I think Subaru tossed a really good engine here because of political pressure, and I'm glad I have one, even if the car is not of the same high quality of previous Subaru's.

My 2015 MB E220 had AdBlue/BlueTEC system. NOx sensors failed EVERY year - a painful expense... Hated it (but the car was a nice drive, clean and good MPG)

How about adding unneeded tiny tanks of adblue to the jets of millionaires and billionaires flying halfway around the planet for their monthly SAVE-THE-PLANETS conference in Tahiti? I'm sure it won't be inconvenient if the engines stop every fifteen minutes at 30,000 feet during the trip.🤣

Hi John, here in the UK my Amarok 2018 does have Adblue. A neccessary evil says I, but boy is it temperamental. At one point a warning light came up to say I had "too much oil", (dealer had serviced it for warranty purposes). I did have too much oil purely down to the level rising because of the adblue overdosing! Who knew!

Remember kids - there's no such thing as a dumb question. Unless it's being asked of the auto expert.

John, Could you do a video about add-on Propane Injection. I have seen these mentioned as a small performance enhancement on diesels and maybe also gasoline engines. I realize they aren't like a nitrous injection system but used to help a truck or motorhome climb a long or steep grade for a little extra oomph. Even a simple system that only provides and extra 20-30HP can be helpful at times. What is the story on these units and their applications?

Ad Blue its great for the garden makes everything grow really good !!!!!!!

Problems 1 and 2 are common in Australia currently.

I lot of diesel vehicle (that incorporate a DPF) owners don’t understand that after each regeneration there is a very small layer of ash left as a residual. This ash cannot be burnt off and builds up very slowly over time. So at some point (generally around 150,000 klms-but this is VERY generally) they will need either a professional method of on car cleaning, or the DPF gets removed and sent to a specialist cleaning shop that have expensive equipment that in 99% of cases can clean them with a test report to prove the results. It will be almost like new. DPFs can fail, though this is rare. The ceramic core can crack for a variety of reasons. A replacement DPF is very expensive to replace with a new one. Best not to modify ANYTHING in the engine, exhaust, tune as this could have “unintended consequences”. I speak from experience.

Politicians can fill your adblue tank 😂because they are full of it 😂

In "Murikkka, all diesels now require a DPF and AdBlue for the double whammy of maintenance nightmares.

I had a frustrating experience with a 2017 Peugeot Euro 6 diesel six months ago. I left Melbourne en-route to Newcastle in NSW. The dashboard indicator was telling me I still had over 5,000 kms of Adblue fluid in the tank. After driving 600 kms, a warning light flashed up with chimes informing me that my Adblue was low and I could only drive another 1,200 kms before engine starting was disabled. I stopped overnight in Parkes and bought some Adblue fluid and added it to the Adblue tank. Still the warnings persisted. After arriving in Newcastle I went to two different mechanics who connected their scanners and tried to reset the error message, but to no avail. The Adblue tank was filled to the brim but it still made no difference. I tried calling the local Peugeot service centre and they were booked out for weeks. In the end I called the Artarmon service centre in Sydney. They were also booked out for 2 weeks but thankfully agreed to look at the issue anyway. They had the car for 30 minutes and had to do a re-set to clear the error. I drove away happy and stayed overnight in Sydney. The next morning - a Saturday morning - about 100 kms out of Sydney, the error came back with the same warning. Luckily I could still get back to Melbourne and booked it in with my local Peugeot service centre (again, a 2 week wait). They discovered the Adblue tank had a leak, and needed a completely new tank. These tanks are over $2,000 each. And this tank was a replacement for a previously split tank. So my car is now on its 3rd Adblue tank in six years. Just love Peugeot's Euro 6 system.😠

My car (BMW F30 335d 2017) is Euro6 and ULEZ compliant, but it definitely does not use AdBlu!

A very informative video. Here in NZ I drive an off road euro truck totally in the forest/Bush and it uses adblue or it won't go!!. But all the forest harvesting machinery use far more diesel than the trucks don't require adblue . Where is the logic in this?? Poor possums breathing in all the shit from the machinery but at least the trucks are helping with clean possum air!! Keep up the good videos (dude)

Have a 2013 Peugeot Partner diesel van, which has a DPF and a bladder of Adblue which is located down the rear under the floor pan. It is automatically blended with the diesel. Of course this has to be installed by Peugeot and computer updated for the remaining kms to empty. However it will notify you that ad blue needs to be refilled, i have to say JC that the engine doesnt stop running.. just annoying chime notifications that its empty.
