AdBlue is one third urea and two thirds water. That means the stuff is REAL cheap to produce. They could sell it at a buck a gallon and make a fortune.
Well, that sort of thing is the genesis of my question. That is, if the low level indicator trips, and you fill the reservoir, will the low level sensor reset? It strikes me that EPA/CARB may not allow that, because it could be gamed by putting in a non-approved (and likely cheaper) substitute. Being basically paranoid, especially about EPA/CARB, I suspect that refilling the reservoir alone will not reset the indicator and instead it has to be reset by a 'qualified' person using special equipment to ensure that the approved fluid is used.

Adding Adblue to an AUDI, BMW, MB or VW is simple as removing a cap and pouring in the liquid. If you let the MB run dry you get 20 starts before it will not start. It then takes 2 gallons to reset the sensor. Buying Adblue will become as simple as getting oil very soon. You can order it from Impex. A 2.5 gallon container is $14.87. If CR really wanted to provide an honest assessment of the AdBlue systems being sold by the 4 different automakers they would have done a little research. They leave a lot to be desired as a research company. That $300+ AdBlue visit should have cost $45. That is less than 3/10ths of a cent per mile.
I too was concerned about Adblue. After a little research I am perfectly comfortable owning one. BMW keeps it full the first 50,000 miles.

A solution to that would be to add AdBlue before the sensor is tripped. If the sensor is simply working on level and does not have a "mileage input signal" then one could simply add Ad-Blue when it was 2/3 depleted, and never set the sensor off. I don't think the sensor needs to be reset by a technician anymore than your low-fuel level alarm has to be reset, if you run your tank low. There's nothing stopping you from putting some non-EPA/CARB fluid in your fuel right?
