This video features a Renault Master with a Siemens SID321 engine ECU. The vehicle had arrived from Poland, and work on its AdBlue system had already been carried out by the time of filming. After the ignition was switched on, no AdBlue warning was displayed on the dashboard.

A service reminder remained on the instrument panel. The video identifies it as a reminder to replace the brake pads, unrelated to the exhaust after-treatment system. The workshop also says it works on DPF-related faults in Renault Master, Nissan Navara and Opel Movano vehicles equipped with the SID321 ECU.

The video does not show specific fault codes or a road test after the work, so it confirms only the AdBlue status shown on the dashboard. A DPF repair result is not demonstrated in this case.
