Citroën Grand C4 SpaceTourer MD1CS003 AdBlue (SCR) Removal Emulator
Plug-in AdBlue SCR removal emulator for the Citroën Grand C4 SpaceTourer MD1CS003 — clears all SCR fault codes and warning lights so your seven-seat MPV runs at full capacity.
The Citroën Grand C4 SpaceTourer is a seven-seat MPV built for large families and long-distance travel, running on the MD1CS003 ECU platform. When AdBlue crystallisation, a dosing pump failure or a NOx sensor fault triggers the engine warning light, this spacious MPV can be reduced to limp mode at the worst possible moment. This MD1CS003 AdBlue removal emulator electronically simulates the entire SCR system, delivering all the signals the ECU requires to confirm fault-free operation — so your Grand C4 SpaceTourer continues running at full capacity without warning lights, power cuts or recurring AdBlue (DEF) expense.
How Does It Work?
The emulator plugs directly into the Grand C4 SpaceTourer's original AdBlue system connector with no wire cutting or soldering required. It transmits continuously valid AdBlue fluid level, SCR catalyst status and NOx sensor values to the MD1CS003 ECU, which processes this data as normal system operation and generates no fault codes or driving restrictions.
