To resolve DPF issues, follow these steps:

1. Perform a Regeneration Cycle: Drive the vehicle at a constant speed of around 60 km/h (37 mph) for 20-30 minutes. This allows the DPF to heat up and burn off accumulated soot.
2. Check for Fault Codes: Use an OBD-II scanner to identify any fault codes related to the DPF. Follow the manual’s troubleshooting guide to clear the codes.
3. Inspect the Exhaust System: Ensure there are no blockages or leaks in the exhaust system that might affect the DPF’s performance.

Our manual provides comprehensive instructions for managing DPF problems to help keep your vehicle running smoothly.
