The use of this device leads to increased exhaust gas emissions. Once you install and use an AdBlue removal emulator, your truck no longer complies with Euro 4, Euro 5, or Euro 6 emission standards. Our device is intended only for use in countries where Euro 4/5/6 environmental regulations are not enforced. The AdBlue removal emulator disables the flow of DEF (Diesel Exhaust Fluid) within the SCR system. Purchasing and using this device is a personal decision.
