VW Crafter MD1CS104 AdBlue SCR + DPF Removal Emulator
A plug-and-play AdBlue SCR + DPF removal emulator for the Volkswagen Crafter MD1CS104 — resolves pump faults, NOx errors, and DPF blockages in a single installation with no wire cutting.
The MD1CS104 engine management platform in the Volkswagen Crafter presents a demanding set of emission-system challenges: AdBlue pump failures, NOx sensor faults, DEF crystallisation blocking the dosing unit, and DPF blockages can individually trigger torque derate and speed restrictions — and when they occur together, the vehicle can be rendered undriveable. The Volkswagen Crafter MD1CS104 AdBlue SCR + DPF Removal Emulator resolves all of these issues in a single installation. It simultaneously simulates both the SCR and DPF control circuits, so the ECU permanently sees a fully functioning emission system without any fault codes or warning alerts.
How Does It Work?
The emulator connects directly to the original OEM connectors for both the AdBlue/SCR and DPF control circuits on the MD1CS104 harness — no wire cutting or soldering is required. The device generates real-time signals for NOx sensor inlet and outlet values, AdBlue level, quality and temperature data, DPF differential pressure, SCR catalyst temperature feedback, and the AdBlue dosing pump control line. The engine management unit receives all parameters within normal range and therefore generates no fault codes, allowing the vehicle to operate at full power without restriction.
Frequently Asked Questions
Is this emulator exclusive to the Volkswagen Crafter?
Yes. It is engineered specifically for the MD1CS104 ECU and is primarily intended for Volkswagen Crafter models equipped with that engine management system.
Are the SCR and DPF systems disabled simultaneously?
Yes. This version simulates both the SCR and DPF control circuits, so faults from both systems are resolved in a single plug-in installation.
Does the AdBlue tank need to be emptied before fitting?
No. Once the emulator is connected, the system ceases to consume AdBlue (DEF), so any fluid remaining in the tank can stay without issue.
What warranty and shipping options are available?
All our products carry a 2-year warranty. Please refer to our returns and warranty policy for full terms. International shipping is available on request.
