DPF filter change on the A3 motorway in Germany.
On 20.04.2021, a trucker from Moldova contacted the international road assistance service AWHelp24. On the way to Nuremberg, the DPF (Diesel Particulate Filter) regeneration indicator on the dashboard of his Volvo truck activated. This was the first indication that the filter was 40% blocked. The second indication was that the filter was actively regenerating at short intervals over the last few days.
Contamination of the DPF filter with ash increases the back pressure of the exhaust gases, which leads to higher fuel consumption. In addition, the accumulation of ash also reduces the capacity of the particulate filter. The service mechanics carried out diagnostics, which revealed that the DPF particulate filter had to be replaced. The technicians replaced the filter in minimal time, provided the driver with instructions and the vehicle was able to continue on its route.
