How can I prevent DPF faults?
Simple habits help: take your vehicle on occasional longer journeys, regularly drive on highways for 20-30 minutes above 2,500 RPM to help the DPF regenerate, use good-quality diesel, and keep the engine well-maintained, always using low-ash, manufacturer-approved engine oil. Avoiding frequent short trips also gives your DPF a better chance to regenerate naturally. Address Warning Lights: Don’t ignore the DPF warning light; get it checked by a professional.
