AdBlue (SCR) Øveraasen Mercedes Engine AdBlue SCR Removal Emulator
Permanently eliminates AdBlue and SCR fault lights on Øveraasen Mercedes-engined machines, preventing power derates during mission-critical winter operations.
Øveraasen snow clearing and airport runway maintenance machines operate in some of the harshest winter environments imaginable — conditions where a breakdown during peak snowfall can have serious safety and operational consequences. The Mercedes-sourced engines fitted to these machines use an SCR system that is particularly susceptible to AdBlue (DEF) freezing, crystallisation, dosing pump failure, and NOx sensor drift in sub-zero temperatures. When any of these faults occur, the ECU forces the machine into a reduced-power safe mode at exactly the moment full output is most critical. The Øveraasen (Mercedes Engine) AdBlue (SCR) Removal Emulator permanently eliminates these faults by electronically simulating all SCR circuit signals, keeping the machine at full power regardless of conditions.
How Does It Work?
The emulator plugs directly into the Mercedes engine management unit's SCR connector via the original factory socket — no wire cutting, no soldering, and no permanent modification to the vehicle's wiring. Once connected, it continuously generates valid NOx inlet and outlet sensor signals, AdBlue dosing pump feedback, and urea tank level and temperature data within the value ranges the ECU expects. Crucially, it maintains stable signal output even at extreme low temperatures. The ECU sees a healthy, fully functional SCR system at all times, logs no fault codes, and never commands a power derate or limp mode.
Frequently Asked Questions
Is this emulator compatible with all Øveraasen machines fitted with Mercedes engines?
It is designed for Øveraasen machines equipped with Mercedes-sourced engines and SCR systems. We recommend sharing the engine type and ECU reference before ordering to confirm an exact match.
Can it be installed in cold-weather field conditions?
Yes. The emulator connects via the original factory connector using a plug-and-play fit — no wire cutting or soldering required. It is also designed to operate stably at low temperatures once installed.
Can the emulator be removed later to restore the original SCR system?
Yes. Because no permanent changes are made to the vehicle's wiring or hardware, the emulator can be unplugged at any time and the machine will revert to its factory SCR behaviour.
Who is responsible for compliance with local emissions regulations?
Intervention in an emissions control system is subject to local legislation in many jurisdictions. Responsibility for lawful use rests with the operator. Always check applicable regulations before use on public roads or public areas.
