Really good explanation. Have a new (old) Diesel car and the Adblue is the new thing for me, as well as the NOX sensor (which I've just had replaced). Found the filler for it in the back of the car and wondered what AdBlue was and how it works.
Best video on the FULL explanation of adblue. Thank you so much. Inwas wondering if the adblue tank was crystallised because the line was empty. Now i know that it is pumped back in the tank.
Excellent excellent explanation. This system ads so much complexity to diesel engines. Don't think electric cars are not complex. Their complexity is different, but still overly complex. Petrol is still the best way to go.
You state that 30% urea is used for its freezing point,does that mean if cold was not a concern would a higher % mean less adblue volume needed to be injected for the same results?
My son in laws car broke down the other day Ad Blue problem.It was repaired by Peugeot he had problems before.The AA man said to him I can't do anything with this car has to go back to the dealership.Drove him and the car to a garage.He just paid over a thousand pounds for repairs.So another thing to go horrible wrong with a modern diesel arn't we happy.
I see that the passage from the catalyst to the particulate filter does not have direct access because it has gas flow deflectors. I was thinking of cleaning my dpf through the Addblue inlet, going down to the particulate filter, but thanks to your video I see that I won't be able to do it.
Hi very interesting video you are professional engineer just question I have audi A6 ....2016 year its only done 40000 miles from new and its coming up with p20e800 code low pressure and the adblue tank is full now when the engine is cold does the adblue injector spray the adblue?? Or the engine have to be at normal temperature ie 90° Celsius and then the adblue injector works ? Please kindly help me on this on this issue waiting for your reply Thankyou 🙏
Hey thanks for the comments, I’ve worked in the automotive trade many years. Could be a couple of things, this is a bit of a generic fault code so the system needs to be checked, yes it will work from cold if needed, depends on how much Nox emissions are produced. This Fault code could relate to an issue with the pump, it’s common for the AdBlue system to become blocked. As it’s full, that rules out low fluid. There’s also been software updates, which could be needed if there’s no other obvious faults
Absolutely unbelieveable. Why would it have to be so complicated? Just how clean are the exhaust gases? If they're practically clean as a whistle why are these engines being banned. And how does a diesel engine running with ad blue complare with a modern petrol engined car? Which is cleanest. No wonder some hapless motorhome owners have had to pay thousands out for new ad blue tanks. This ad blue just isn't good enough. It's got a very short shelf life and starts to chrystalise and knacker the tank up. For this reason I wouldn't buy a diesel car that runs on ad blue. But what a good video. It's really opened my eyes to just how complicated and these things are. I've seen inside modern televisions and they aren't this convoluted.
No wonder new vehicles are expensive. That's a complex system added to an exhaust! Is the exhaust fluid added before or after the headlight and taillight fluids?
QUESTION: I've got a new Nercedes GLC Coupe 300. There is an intermittent throbbing noise coming from the engine. My local Merce dealer said it is from AdBlue injector and it is normal. The car is brand new and I found it very loud as my previous Mercedes's did not have this issue despite all having AdBlue? How can I find out whether or not they are lying?
So the add blue dosnt go into the fuel tank? The other question what impact would it have on a vans engine if I were to gut the dpf and software delete it, would this be ok? Thanks
Hey! I have question about valve in exhaust pipe after ammonia trap (can see at 6:58 in video)? What it is called? I can't find any information in google about that valve, but i want read something about it. Thanks!
thank you for your video. Peugeot, on his 308 Bluehdi models has problems with the Adblue tank. Every car, at around 50000-60 000km has to replace the tank. It arrives suddenly as Check Engine+Adblue+Service it is almost 1000€ cost They say the tank is deforming because of wrong pressure
@Little Reptilian i dont know. The "new" tank has the same part number so probably no modification has been done. For now I am filling the tank every month, not letting the urea form cristals
I have a Peugeot 308 with 67000 km and I had a problema with the adblue injector… it really seems that it is a faulty system. However, I only had to replace the injector. In your case did the dealer covered the costs of repairment?
i think you've found the reason this system was invented for! If they've wanted cleaner exhaust air, they've could put a physical filter to the rear with a filter that needs to be replaced every week or so...
Good question, but I’m not sure to be honest but it will likely cause an issue, the system will detect that the AdBlue fluid is not doing what it’s supposed to do and then put the warning light on and stop working. That might mean you’ll need to flush the system out.
egr, dpf/dpd, scr, adblue etc...with so many expensive imission device you put in eternal combustion engine still not perfect to make the air clean ang breathable when you put your nose in the exhaust pipe and it cause headache of low power issue in the engine..how about the electric power plant that uses coal fuel, did they use thise kind of device to reduce air pollution or not?

P20EE would indicate an issue with the adblue system, first check the quality of the adblue fluid. If its been filled with water for example. The other common issue is the injector can become blocked. you could try taking it off and soaking the end in hot water to try and clear it.
I don’t have any data to suggest it does, you normally find the engines get more fuel efficient. The DPF system will use additional fuel in the burn off phase where it uses heat to burn off the soot.

Jack d Modern vehicles are all junk,too much electronics and stuff you don’t really need then when it goes wrong it costs an arm and a leg to fix that’s if you can actually find where the fault lies
Working EGR must have a larger effect on NOx by reducing combustion temperature and by effectively reducing cylinder capacity by introducing exhaust gases into the cylinder. Why not introduce higher volume but better filtered EGR exhaust gas into cylinders at cruise?
ADBLUE is simply common DEF (Diesel Exhaust Fluid), sold under a variety of names. There is literally no harm in using other manufacturers' brands of DEF as a replacement to Volkswagen's ADBLUE-branded fluid. Usually, 2.5 gallons of DEF goes for around $17-22, which should fill your DEF tank for at least 8,000 to 12,000 miles, depending on how aggressively you drive the TDi.
I would love to somehow fit this on my euro 4 non dpf diesel. Even though this causes trouble on the long run... at least the car does not polute that much...
Diesels used to be the greatest engine in the world for land based transport, now money men and bean counters have turned them into unreliable and bloody expensive piles of junk.

The best thing with Adblue is the amount of damage it can do if you put in the fuel. It's also good for making crystals
You state that 30% urea is used for its freezing point,does that mean if cold was not a concern would a higher % mean less adblue volume needed to be injected for the same results?
