The sensor down stream of the SCR can tell the difference. After the process of the add blue being added and the catalytic reaction the sensor expects to “sniff” a specific content of gases if these gases fall outside of the correct window of operation the system tends to log an efficiency fault code something like P20EE.

The match of 250 miles to detect and clear the fault indicate it's probably a sensor further down the injection system rather than in the tank itself. The fluid in the pipe between the tank and injectors needs to be used before the content in the tank reaches that sensor.

When Add Blue is added, the temperature in the exhaust system is raised. It is at process that depends of a number of factors, like the outdoor temperature, driving speed etc. The system that monitors the exhaust, measures the temperature, and will calculate this rise in temperature over a period. If the temperature is not matching the expected rise, something is wrong with the Add Blue. With information from other sensors in the system, the monitoring system can determine what is wrong, and this will give you a dashboard indication. The reason it takes 250 miles for the system to figure out what is wrong, is that other factors that affect the exhaust temperature, must be ruled out first, and that takes time.

I can't say whether this bullshit or not, but I do know that in our American heavy trucks, you call them Lorrys, there is a sensor inside the DEF tank that reads the tank pH. Urea is acidic, uric acid. The sensor takes multiple readings using electric pulses. The computer knows that water containing 13% uric acid and a certain other percentage of ammonia will come back with a specific voltage and anything outside of the parameters will trigger it as low quality exhaust fluid. As for the 250 mi thing, I don't know what the hell this guy's talking about, maybe it's different for cars but in our trucks the computer monitors and checks itself every 15 minutes and after three failed checks it will trigger a problem and will not reset itself back to normal until it gets three clean 15-minute checks.

@@rattlecanmaster The system has nitrous oxide (nox) sensors before and after the treatment unit in the exhaust. As long as the readings are being reduced enough by the trap for the sensors show sufficient reduction in nox the system is happy. When the reduction is insufficient, the system injects more ad blue into the ceramic matrix in the exhaust, and expects to see a increase in nox reduction. If it sees no change the money light comes on because it knows something is wrong. If you dilute your ad blue with water the active chemicals will be used up quicker and it will inject more often, and will in fact only go as far as the amount of ad blue in the solution allows. Hence you will get no more miles by diluting it! people mistakenly think this stuff is continually injected, not the case. the 250 miles probably equates to how far you have to travel before the solution in the pipe between the tank and the injector in the exhaust is purged. At the dealers their software has a purge function, to run the pump and injector without the car moving to clear bad solution from the line. You also need to be aware that ad blue goes off after time in storage. If you open a pack and it smells strongly of ammonia don`t use it it will not work properly and can bring the money light on. Ad blue should be stored out of direct sunlight and below 25 degrees centigrade. so if your garage has a stack of it on the forecourt in the heat and sunlight, the chances are it will be bad. even if it is only half bad it will be used up twice as quickly by your car as the reduction in active chemical will be just the same as watering it down.

There is also a NoX sensor before after the SCR catalyst and looks for a 60% or better reduction in NoX. During a shortage of adblue or apocalypse it could keep you mobile though.

Greetings from California. Let me tell you, I'm just running into that. I once did it. I added probably 500 ml of distilled water; is the only one that can work, tap water wont make the trick because its minerals and impurities and the sensor will catch it fast; to my wife's X5 35d and it helped to clean some stubborn codes that were making to fail the smog inspections required by law every other year in California in order to register your car. It worked! After doing that, this year I'm having some codes with the Nox sensor in my beloved small beast 2011 335d, so I decided to do the same trick. Well, since last time worked like a charm, this time I probably added way too much water, almost a gallon of distilled water to the brand new DEF liquid from BMW, it went well and it happened the same like happened to you. The Sensor It didn't recognized it at the beginning but after about 100 miles, finally the car told me it had the good DEF. For about 300 miles it ran without any countdown warning, added it when I had only less than 150 miles, since I wanted the water to clear things inside. But I guess it was a bad idea since after those 300 miles of driving without any issue, last week came back the 200-mile warning saying "Bad Nox Exhausted Liquid..." So this time I'm guessing it was too much water in the mix and the sensor caught it, I tried to add more DEF to make the system recognized the real deal is in the tank but it didn't work. So I just finished draining the active and passive tanks, I used a siphon pump, $7 in your local hardware store and it makes the process to be over in less than 10 minutes, and then I added about 1.75 Gallons of BMW DEF, the only issue is that my countdown is just about 24 miles! I drove it for a little bit but still bad Nox fluid code is there!!!. What I will do is to leave the engine on for about an hour or so, right now is winter in CALIFORNIA and is about 43⁰ F, so it's way too cold for this part of the state, not far from Malibu. Then I will drive it for over 150 miles hoping this thing doesn't shutdown in the middle of the freeway when the 24 miles warning runs out. So lesson learn, the sensor will catch the imbalance ratio between Urea and distilled water. You can add a little of distilled water but absolutely it won't replace the urea. Don't try it at home. Now pray for me so this stupid code goes away.

Then after you've spent a small fortune having the DPF reconditioned over and over before just removing it, then getting spot checked, then paying a huge fine to stop the gov taking your car, then putting it back in, then spending £72 a tank for diesel, you might just start putting random slish in the Adblue tank. Thankfully though modern cars now deny you use of your product you've paid money to own, if you do things like this. I'm glad I'm normal and have an EV, well, my second one now, first one caught fire and this one broke down last week, well I say broke down but I ran out of charge because the services were full and I foolishgly thought if I just drove gently, it'd make it home.

The system takes no notice of what you put in the tank - it works by measuring the exhaust gases, after the adblue injection in the exhaust, and it expects a specific range of emmisions/Nox - if you've got adblue in the Nox results will be in range - anything else, water, tea, coffee and the figures will be wrong and upshoots your fault message

It's a bit of a mixed bag with these. The AdBlue system burns some of the NOx that Diesel engines put out, so they have an effect on the emissions. Which would make them useful. The DPF however breaks down larger particles and creates microparticles, which in turn means yes, the emissions *look* cleaner, since there are no "big" soot particles, but those soot particles just fall to the ground while the broken up microparticles are getting everywhere, including your lungs. I have a pre-DPF-car and I'm glad it works that way (although I pay a penalty because politicians fall for that DPF propaganda crap). The catalysator decreases CO emissions while at the same time increasing CO2 emissions, so I'd say it takes one kind of pollution into another. So meh... Btw. since CO is the real killer (not CO2 as the politicians seem to believe), I find it fascinating that all the emission tests tend to focus on CO2. Looks almost like someone in the petrol engine lobby had a finger in those emission laws, since those are the real stinkers (just speaking figuratively, CO is as odorless as CO2, but uinlike CO2 it can poison you) when it comes to CO.

A few key elements: Urea (ammonia diluted in water) is used to reduce NOx emissions, by oxidizing the NOx with NH3 and obtaining N2 and H2O (nitrogen and water). A diesel car with all 3 EGR, DPF and adBlue deactivated smells distinctively. Some cops (here in Europe) know that and the fines are discouraging... Better buy a smaller engine car (below 100 bhp) as they come without an adBlue system.

Could you just reprogramme or disable the computer to bypass the AdBlu sensors?

No chance if they were able to check strength of the liquid that would be amazing! You can get these deleted by ecu programmers it will be due to emissions like the lamda hence it needs running to clear the water in the system

I imagine it works on conductivity between two probes. A 66% water/33% urea mix will have a specific conductivity that is different to just water and it just measures this continuously. My guess anyway.

I don't know about cars, but most Euro 6 trucks have an AdBlue quality sensor which measures the urea concentration (should be 32%) of the AdBlue in the tank, one way to measure it is the electrical conductivity. The sensor can see if it's water, AdBlue or even diesel that was filled into the tank. This type of sensor is required for the vehicle to be legislated to Euro 6, not sure of this was present for Euro 5 as well. The 250 miles indicates that the system wants to see Nox conversion to reset the AdBlue warning. Even dealerships can't just reset these as it would be illegal, all of this is described in EU law texts.

People have speculated on diluting it further, but what if you increased the concentration?, would the sensor register the effect and then inject less as the NOx was cut back, I haven't looked but it may be possible to buy urea in more concentrated forms, so if this worked it may be a cost saving or at least a way of keeping your vehicle on the road if adblue stocks were difficult to obtain.

I usually top up the adblue on my Ranger as soon as I get the first warning. It typically takes it about 20 miles before it registers and resets the counter. After reading some of the comments on here, all I can suggest is to do the following: When the car tells you the Adblue is running low, it's trying to help you out. So swing by motor world and buy a bottle of it and save yourself some grief. So much simpler than trying to cheat an expensive system that was designed by someone far smarter than any of us. The alternative is to drive something other than a diesel vehicle.

Instead of solving the problem they make you buy adblue! (Its not a coincidence that Adblue arrived as VW and others were facing legal action!). So, lets not fix the problem, lets get the customer to pay for it so that we can all pretend to be green! Like most green legislation its nothing more than a profit generation scam.

I imagine it's because some bus (or van) models that have diesel engines are sold in some countries with AdBlue tanks and in some countries without them.

I doubt it's the adblue sensor in the tank that triggers the error to occur. That is there to mainly ensure the correct level and flow rates are being observed. It's more likely the sensors in the exhaust. The ECM has several downstream exhaust sensors that measure several aspects of the emmissions control systems. These include; Exhaust gas temperature (both pre-DPF and at the DPF) NOX levels pre-DPF DPF pressure differential SCR catalyst performance If any one of these values read out of the ordinary then the engine computer can do one of the following; 1: Command the EGR open to recirculate exhaust gas into the engine to cool the combustion, reducing NOX before the DPF 2: Command a particulate filter regeneration, or display a DPF restriction warning if the exhaust temperatures are insufficient for passive or active regeneration of the DPF, or the DPF is loaded with ash that doesn't burn off. 3: display an AdBlue system fault warning on the dash and prevent the engine being restarted until the SCR has been serviced. in the case of 3, there are sensors after the SCR which detect the presence of residual NOX emmissions. Diesel exhaust fluid (DEF) is designed to be a catalyst which breaks down these NOX emissions. If the ECM detects a NOX level that exceeds its expected values, this is cause for a fault code to be triggered and the ECM will prevent the engine being restarted until the fault is reset and the SCR is cleaned and refilled woth good DEF or other components serviced if, say, the DEF pump fails. Might be worth mentioning too, the SCR doesn't use a lot of DEF when it's doing its job properly. The 250-500 mile delta between the AdBlue warnings appearing and disappearing post-fill is likely due to the SCR supply lines clearing and the vehicle detecting the presence of NOX post-SCR.

you can measure the resistance of the liquid and try to feed the same resistance to the sensor output, mostlikely uses a type of resistor to measure condutivity, tap water should be way diferent, or you can possibly get bicarbonate and after you know the true value that adblue gives, try to measure the condutivity from the water and in real time time try to add the bicarbonate little by little until you get a condutivity match number. Remember to stour it up the water as you add XD brief explanation bicarbonate will increase conductivity gradually as the levels of bicarbonate increase inside the water, so you can see for how many liters of water you should add how many grams of bicarbonate... best water should be demineralized water to have the best consistent results... hope it help some one :)

What surprised me was you had 55miles before the car would be imobilised. I thought it was much more. As the adblue injection only takes affect when the detected level of nox is high. When levels are reduced which will happen depending on engine load. The injection will be reduced or stopped. My car just reports I need to refill every time I start the engine. When it will give up warning I'm not sure offhand.

Put simply if you want to run on water full time you can, but you will require a good diagnostic computer ,simply reset addblue concentration value to 32% each time eml comes on ,but it's probably easier to just use add blue ,hope this helps
