The SCR (Selective Catalytic Reduction) system uses AdBlue, a urea-based solution, injected into the exhaust gases to reduce nitrogen oxide (NOx) emissions in diesel engines. This device is designed to comply with strict environmental standards.
AdBlue / SCR removal consists of electronically disabling the system through ECU (engine control unit) reprogramming. This neutralizes AdBlue-related warnings and faults while optimizing engine performance.
The AdBlue / SCR system is essential to reduce NOx, which causes air pollution and respiratory diseases. It is mandatory on many modern diesel vehicles to comply with Euro 6 standards.
An engine freed from the SCR system gains responsiveness and overall efficiency.
No more refilling the AdBlue tank or replacing faulty SCR components.
No more AdBlue error messages that may restrict vehicle performance.
AdBlue removal is illegal on public roads and reserved for off-road, export, agricultural or industrial use.
No, not for road use. It is reserved for export vehicles, closed circuits or specific uses (agricultural/industrial).
Mechanically, no. The engine usually works better without SCR since it is no longer restricted by the system. However, NOx emissions increase.
Fewer breakdowns, no AdBlue warnings, lower maintenance costs and a more responsive engine.
AdBlue / SCR removal is increasingly requested by professionals and drivers wishing to free themselves from the constraints of this system. It helps avoid costly breakdowns, improves performance and removes AdBlue-related alerts. However, it increases NOx emissions and must be considered carefully, in compliance with current regulations.
