AdBlue is a water-based urea solution used in diesel vehicles to further reduce NOX emissions in addition to the EGR system to achieve EURO 6 standards, the adblue converts some of the remaining NOX to water vapor and nitrogen.
AdBlue is a clear, non-toxic and high-purity urea solution of ammonia and 32.5% in demineralized water, among others. The additive is injected into the exhaust gas directly into the SCR/NOX catalyst located in the exhaust behind the particulate filter. A disadvantage of Adblue is that it crystallizes and it is a corrosive liquid for metals, this crystallization clogs or damages mechanical components. For example, the NOX sensors, adblue injector, the SCR catalytic converter or the adblue pump/tank. With many brands, these are expensive parts, an adblue pump and attached module can in some brands repair costs already towards 2000,- euro or even higher.
Continuing to drive with an empty or broken adblue system is not a solution. With many models, in addition to an error message in the dashboard, the car starts counting down and after x number of kilometers the car can no longer be started and the car must be reset with a special diagnostic tester, after this one can then start once to make a single trip
to the garage for repair or filling.

We received the information below from the RDW;
“The answer is that the removal (or deactivation) of the Adblue system, which is part of the emission control system, is considered a ‘change of construction’ under Vehicle Regulations.” If is changed then you are required to have the registration number updated by presenting the vehicle for inspection at an RDW inspection station.
The emission values, established when the vehicle is admitted, are taken from the vehicle registration register. Unless it is demonstrated with certificates that the vehicle again meets certain emission values.”
Deactivation of the adblue system starts at 225,- euros depending on make and model. the later reactivation due to repair is free of charge.
