Mercedes Citan MD1CS006 AdBlue SCR+DPF Removal Emulator

The Mercedes Citan is a workhorse of urban delivery and service operations, but its MD1CS006-controlled AdBlue (SCR) and DPF systems become a chronic source of faults in the short-run, stop-start duty cycles that define city use. On short urban routes where exhaust temperatures rarely reach the level needed for active regeneration, DPF blockages are almost inevitable — and AdBlue dosing faults or NOx sensor errors compound the problem, triggering engine limiters that bring vans to a standstill at the least convenient moment. This emulator is engineered for exactly this urban use-case, permanently resolving the SCR and DPF emission system issues that the Citan's MD1CS006 platform generates in city environments.

How Does It Work?

The emulator plugs directly into the Mercedes Citan's MD1CS006 ECU connection socket with no wire cutting or soldering required. Once connected, the device fully simulates all parameters the ECU monitors across the emission systems: upstream and downstream NOx sensors, PM (Particulate Matter) sensor, AdBlue tank temperature and level sensor, AdBlue pump feedback signal, SCR catalyst temperature, and DPF differential pressure and exhaust temperature readings. The vehicle ECU reads all SCR and DPF systems as functioning normally, runs the engine at full power, and generates no fault codes.
