AdBlue is a special liquid used in SCR system (Selective Catalytic Reduction). It is a water solution containing urea at 32.5% of the nominal concentration. The main reason for using AdBlue is to reduce nitrogen oxide emissions. Unfortunately, this system creates very high costs.

Adblue is stored in a separate tank. On different models, the entrance to the tank is in various places, for example in the trunk, under the hood or near the neck of the diesel tank. From the tank, the mixture reaches the SCR catalyst, where nitrogen oxides are reduced to harmless water and nitrogen.

The AdBlue and SCR system is complex and prone to malfunctions. Electronic nitrogen sensors, modules, pumps - all these devices can malfunction and are costly to replace them. In vehicles that travel hundreds of kilometers, you should also fill up the Adblue tank regularly.

All of this creates additional driving costs that drivers want to avoid.

The AdBlue shutdown service is the electronic deactivation of AdBlue by removing the dashboard lights and warning messages in the ECU associated with the system.

In most cases it is sufficient to reprogram the engine management system accordingly. In some models it is also necessary to detach the SCR unit from the vehicle.


The Adblue system reduces nitrogen oxides in combustion gases, which is good for the environment and human health. However, AdBlue also has many disadvantages, and many drivers consider disabling the system.

complex system susceptible to damage - comprehensive repair can cost several thousand dollars,
solution - solidifies at 11 ¬į C (12.2 ¬į F) - a faulty heater in the tank can cause crystals to form which can block the injection system and lead to pump failure
frequent fluid refills required
the solution is extremely corrosive - the spilled liquid must be wiped off quickly so as not to damage the paint coating and the anti-corrosion coating.
