Renault Captur / QM3 MD1CS006 AdBlue SCR+DPF Removal Emulator

Renault Captur and its QM3 variant share the MD1CS006 ECU platform, and owners of diesel-powered examples frequently encounter a recurring cycle of AdBlue (DEF) faults, NOx sensor warnings and DPF blockages that drive up running costs and trigger limp mode at the worst possible moments. This AdBlue SCR + DPF removal emulator is engineered specifically for the MD1CS006 architecture: it replicates every sensor signal the ECU monitors across both the SCR and DPF circuits simultaneously. The result is a permanently clean OBD scan, zero AdBlue top-up obligation and uninterrupted full-power operation.

How Does It Work?

The emulator connects to the existing MD1CS006 ECU connector without any permanent modification to the vehicle — no wires are cut and no soldering is required. Once active, it simultaneously simulates the AdBlue level, temperature and quality sensor signals, upstream and downstream NOx sensor readings, DCU dosing feedback, and the DPF differential pressure sensor output — all within the parameter ranges the MD1CS006 expects. The ECU interprets these values as valid system outputs and generates no fault codes, so the vehicle never enters torque restriction or limp mode.
