The AdBlue/SCR software was changed on this Renault Master III with a Continental SID321 control unit. After the work, connectors related to the system, including the NOx sensor connector, were disconnected. The video shows the vehicle starting without entering limp mode and the engine responding to the accelerator.

After the control unit changes, diagnostics showed no faults, including on a repeat scan. The vehicle was then road-tested. Engine temperature and pressure readings appeared normal, while AdBlue consumption remained at zero during the test.

This summary reflects the checks shown after the software change and sensor disconnection. It does not indicate that the SCR system continued dosing AdBlue; the video specifically reports no consumption during the test.
