The rise in the price of gas leads to that of AdBlue, which is necessary for the proper functioning of recent diesel engines. This product could even run out, or a car with AdBlue broken down will refuse to start.
Fuels are not the only automotive fluids to be impacted, among other things, by the global increase in the price of energy. This is also the case for AdBlue (and its alternatives Blue +, ClearNOx, etc.). This liquid feeds the SCR catalyst of recent diesel vehicles which are equipped with it, via a dedicated tank, and it is necessary to fill it up during overhauls, or even sometimes between them. It allows the SCR catalyst to transform nitrogen oxides from the exhaust into nitrogen and water vapor that are relatively harmless to our health. It is composed of urea (32.5%) and demineralized water (67.5%). Its manufacture requires ammonia, but the production of ammonia uses methane, and this gas has seen its prices increase considerably. over the past few weeks.
AdBlue is used to feed the SCR catalyst of recent diesels.
AdBlue production significantly slowed down
The largest European suppliers of AdBlue have reduced or even interrupted their production. The German SKW Piesteritz has just announced a 20% reduction in its ammonia production. His compatriot BASF is also slowing down. The Italian firm Yara has decided to suspend its activity for four weeks, and the Slovakian firm Duslo has also put its production on hiatus. As a result, supply difficulties are starting to drive up AdBlue prices in several European countries.

Recent diesel engines shut down in the event of a shortage
Even more worrying than the rise in price, this reduction in AdBlue production could lead to a shortage, or vehicles designed to work with this product will refuse to start if it failseven in the absence of any other mechanical defect. The Slovak government has already ordered 500,000 liters of AdBlue which will be reserved for national carriers. Because road transport, on which a large part of the global economy depends, needs AdBlue in large quantities to drive its diesel trucks. The main French distributors of AdBlue for individuals do not seem to be short of it for the moment, but the situation should be closely monitored.
Water to compensate for the lack of AdBlue
If you run out of AdBlue, it is possible to fill the tank with water (minimum 5 to 10 L). The liquid will deceive the vehicle which will be able to start and drive. However, this solution is only useful for troubleshooting. In fact, the water promotes corrosion in the exhaust system and renders the pollution control system inoperative.
