This 2023 Renault Master had covered approximately 141,000 km when it developed emissions-control system problems. It uses a Siemens SID321 ECU, which requires suitable equipment and experience for programming work.

ECU programming

The video shows software work related to the AdBlue and NOx systems, along with an engine power calibration. The title also mentions the DPF and EGR, but the narration does not detail separate work on those components. No specific power figure or dyno measurement is given.

Checks after programming

The technician ran diagnostics after writing the software. The video reports that no fault codes remained, the engine started, and the warning lights were off. It does not show a separate road-test result or emissions measurement.
