This 2014 Ford Kuga 2.0 TDCi arrived with a recurring DPF warning. The owner had previously had the filter washed at another workshop, but the warning returned soon afterwards. Diagnostics showed a high filter load and an exhaust temperature sensor fault.

Inspection confirmed that the filter remained heavily blocked after washing. The video also explains why temperature sensors and other regeneration parameters need to be checked before cleaning a DPF: if the system cannot start or complete regeneration correctly, washing alone will not resolve the underlying issue.

The engine control unit was reprogrammed, DPF and temperature sensor counters were reset, and the filter housing was modified. The car was checked and returned to the owner; the video shows it in use the following day without the original DPF warning.
