Euro 5 Emission Standard and Why Emulators Are Needed
The Euro 5 standard introduced significantly tighter limits on NOx and particulate emissions from heavy commercial vehicles compared with earlier generations. To comply, manufacturers integrated Selective Catalytic Reduction (SCR) systems and AdBlue (DEF) tanks into their drivetrains. AdBlue — a solution of 32.5% urea in deionised water — converts harmful NOx gases in the exhaust stream into harmless nitrogen and water vapour. When AdBlue pumps fail, injectors clog, NOx sensors degrade, or SCR catalysts develop faults, warning lights illuminate and engine performance drops. Euro 5 emulator devices solve this by sending the correct CAN-bus signals directly to the ECU, clearing fault codes and restoring normal vehicle operation — without relying on a malfunctioning system component.
Supported Makes and Systems
Our Euro 5 category covers Volvo, DAF, Ford, Mercedes-Benz, Iveco, MAN, Renault, Scania, Cummins, Deutz, Mitsubishi Fuso, and New Holland commercial vehicles. Purpose-built emulator devices are available for the different engine and ECU variants found across these brands — including specific cab and engine combinations such as the DAF CF 85 and XF 105. With more than 52 Euro 5 emulator models in stock, the range spans three core device types: AdBlue (SCR) removal emulators, NOx sensor emulators, and DTC fault code erasers.
Device Types: SCR Removal, NOx Emulator, DTC Eraser
AdBlue (SCR) Removal Emulator: This plug-in device generates the CAN-bus signals that tell the ECU the AdBlue (DEF) system is operating normally. AdBlue consumption stops, the AdBlue warning lamp extinguishes, and engine de-rating is prevented. NOx Sensor Emulator: Replaces a faulty or removed NOx sensor by simulating the correct measurement signal in the exhaust stream, eliminating sensor-related fault codes. DTC Fault Code Eraser: Clears stored emission-system diagnostic trouble codes and prevents them from being rewritten, keeping the vehicle clean on diagnostic scans. Multi-brand 10-in-1 emulator devices are also available, supporting several makes and ECU types from a single module — ideal for workshops and fleet operators.
Choosing the Right Euro 5 Emulator
Selecting the correct device requires knowing the vehicle's make, model, engine code, and ECU software version. An emulator built for the DAF XF 105, for example, will not suit a different DAF variant, and Cummins-engined vehicles may use different CAN-bus protocols depending on the ECU revision. Always check the compatibility list on the product page before ordering. If you are unsure of your ECU software number, read it with an OBD scanner and send it to our technical team — we will identify the correct model for you. Installation involves connecting to the vehicle's CAN-bus wiring and should be carried out by a qualified auto-electrician or workshop to avoid ECU damage.

Frequently Asked Questions
Which vehicles are compatible with Euro 5 emulators?
Our Euro 5 category covers commercial vehicles from Volvo, DAF, Ford, Mercedes-Benz, Iveco, MAN, Renault, Scania, Cummins, Deutz, Mitsubishi Fuso, and New Holland. Compatible cab and engine codes are listed on each product page. You must select the device that matches your specific ECU type.
Do I still need to top up AdBlue after fitting an SCR removal emulator?
No. The AdBlue (SCR) removal emulator sends signals to the ECU indicating that the AdBlue system is functioning normally. The vehicle will not be speed-limited or de-rated when the tank runs dry, and there is no longer a need to refill AdBlue (DEF). Note that while the emulator is fitted, the SCR system itself remains physically inactive.
What is the difference between a NOx sensor emulator and a DTC fault code eraser?
A NOx sensor emulator is a physical device that replaces a faulty or removed NOx sensor and feeds the ECU the correct measurement signal. A DTC fault code eraser does not replace any component — it clears recorded fault codes from the system and prevents them from being written back. The two devices serve different purposes and can complement each other.
Can I install the emulator myself?
Emulator devices connect to the vehicle's electrical system via the CAN-bus wiring. Users with a solid background in automotive electrics can follow the included installation guide and video instructions. However, because an incorrect connection can cause ECU damage, we strongly recommend having the device fitted by a professional auto-electrician or specialist workshop.
Are the products covered by a warranty and return policy?
Yes. If a device develops a fault caused by the unit itself, it is replaced or refunded free of charge under warranty. Damage resulting from incorrect installation is not covered. Please refer to our returns and warranty policy for full terms and conditions.
How long does shipping take?
In-stock items are typically shipped free of charge, usually within 1-2 business days. Delivery time then depends on your location but is generally 1–3 working days. A tracking number is emailed to you as soon as the order ships.
