Video tutorial

The video documents an intervention on a Fiat Ducato with issues in the AdBlue system. The engine warning light and the AdBlue warning light illuminated, indicating reduced range.

After refilling, the vehicle shut down, entering protection mode, only after 250 miles. The diagnosis revealed three faults: a faulty AdBlue pump, a non-functioning tank level sensor, and a leak from the pipe between the tank and injector.

The pump, sensor, and damaged pipe were replaced. After reassembly, a regeneration of the diesel particulate filter (DPF) was performed via road test.

The system was tested with diagnostics: the DPF and AdBlue system parameters were within normal limits. The intervention required specific skills and diagnostic tools, which confirmed, after the repair, the absence of errors and correct functioning.
