AdBlue (SCR) CLAAS AdBlue SCR Removal Emulator — Tractor & Combine Harvester
Permanently clears AdBlue SCR fault warnings on CLAAS tractors and combine harvesters, eliminating power derates and downtime throughout the harvest season.
CLAAS tractors, combine harvesters, and forage machines run at full throttle for extended hours during the most time-critical windows of the farming year. Dusty field conditions and sustained high engine loads place the SCR system under constant stress, generating AdBlue (DEF) dosing faults, urea quality warnings, and NOx sensor drift that force power restriction at exactly the wrong moment. In rural locations, getting a dealer technician on site can take days — and in harvest season, a machine down for even a few hours can mean direct crop losses when weather windows are short. The CLAAS AdBlue (SCR) Removal Emulator permanently eliminates these fault conditions electronically, keeping your machine working through the entire season.
How Does It Work?
The emulator plugs into the CLAAS machine's engine control unit connector via the original factory socket — no wire cutting, no soldering, and no permanent modification required, making it straightforward to fit even in field conditions. Once active, it continuously generates valid NOx inlet and outlet sensor signals, AdBlue dosing pump feedback, and urea tank level, temperature, and quality data within the ECU's expected ranges. The ECU reads a healthy, fully operational SCR system, logs no fault codes, and never restricts engine output or PTO performance.
Frequently Asked Questions
Which CLAAS machines is this emulator compatible with?
It is designed for CLAAS diesel tractors, combine harvesters, and forage machines equipped with an AdBlue SCR system — including Arion, Axion, and Xerion tractor series, Lexion and Tucano combines, and Jaguar forage harvesters. Confirm your machine's model and ECU reference via OBD diagnostic equipment or service documentation before ordering.
Can it be fitted in the field without specialist tools?
Yes. The emulator uses a plug-and-play connection to the original factory connector — no wire cutting or soldering required. It can be installed quickly in the field without specialist workshop equipment.
Can the machine be returned to its original configuration after harvest?
Yes. The emulator makes no permanent changes to the machine's wiring or hardware, so it can be removed at any time and the machine will revert to its factory SCR behaviour.
What are the legal considerations for use on public roads?
Modification of exhaust emissions systems is subject to local legislation for vehicles used on public roads. This product is intended for agricultural field use. Responsibility for lawful use rests with the operator.
