EMRT Professional NOx Sensor Emulator – Mercedes Euro 4/5
Internal PCB "Stealth" Solution for Actros, Axor, and Atego
 
The EMRT Professional Mercedes Euro 4/5 PCB Emulator is a high-precision internal solution designed for professional workshops and fleet owners who require a discreet, permanent fix for NOx sensor failures. Engineered to fit directly inside the original sensor electronics housing, this module restores stable communication with the ECM while maintaining a 100% factory appearance.
 
Key Features
Seamless Internal Integration: The custom-engineered PCB board is designed specifically to be housed within the original factory NOx sensor casing, utilizing existing connectors for a clean, "stealth" installation.
High-Fidelity Emulation: Provides the precise digital signal required for optimal SCR system monitoring, effectively preventing "Check Engine" lights and performance-limiting torque derates.
Active SCR Support: Fully compatible with a functioning SCR system. No deactivation is required, making it an ideal long-term solution for vehicles with aging catalysts or declining AdBlue injector efficiency.
Digital Signal Stability: Delivers consistent, high-accuracy nitrogen oxide level readings to the Engine Control Module (ECM), ensuring the vehicle remains out of limp mode even under heavy load.
 
Emulated Components
NOx Sensor (Stable nitrogen oxide level data reporting via CAN-bus).
 
Compatible Vehicle Models
All Mercedes-Benz Euro 4 and Euro 5 heavy-duty platforms:
Mercedes Actros MP II & MP III
Mercedes Atego (Medium-duty distribution)
Mercedes Axor (Regional and construction)
