Citroën C-Elysée MD1CS003 AdBlue SCR Removal Emulator
A plug-and-play CAN-bus emulator that permanently clears all AdBlue and SCR system faults on the Citroën C-Elysée MD1CS003 ECU, removing warning lights and engine restrictions without any wiring changes.
The Citroën C-Elysée pairs its compact sedan form with the MD1CS003 ECU and a Selective Catalytic Reduction system that relies on a steady supply of AdBlue (DEF) fluid. When the SCR system develops faults — whether from a failing AdBlue pump, a drifting NOx sensor or a degraded injector — the C-Elysée responds with persistent warning lights and eventual power restriction. The Citroën C-Elysée MD1CS003 AdBlue (SCR) Removal Emulator is a physical CAN-bus device that replicates every signal the ECU demands from the AdBlue system, eliminating all related fault codes at source without any software intervention.
How Does It Work?
The emulator plugs directly into the C-Elysée's original AdBlue system connector — no wires are cut and no soldering is needed. Its onboard microcontroller continuously generates the AdBlue level, fluid quality, temperature and NOx sensor signals that the MD1CS003 ECU expects, in the precise format the ECU's communication protocol requires. The ECU accepts these signals as valid, treats the system as fully operational and produces neither fault codes nor warning lamps.
Frequently Asked Questions
Is this emulator compatible with Citroën ECUs other than the MD1CS003?
This product is specifically optimised for the MD1CS003 ECU platform. Because the same platform is used across several Citroën, DS, Fiat and Opel models, check the supported vehicle list to confirm fitment for your specific vehicle.
Does fitting the emulator make any permanent changes to the vehicle?
No. The emulator connects via plug-and-play to the existing AdBlue connector. There is no wire cutting, soldering or software modification. The installation is fully reversible.
What does the warranty cover?
All our products carry a 2-year warranty. Please see our returns and warranty policy page for full terms and conditions.
