Diesel Particulate Filter (DPF) Maintenance: Quick Overview
DPFs are crucial for reducing emissions in diesel vehicles, but they need regular maintenance to function well. Here’s a fast guide to understanding DPF maintenance and what to look for:
DPF Maintenance Methods:
- Automatic Cleaning (No Dashboard Message): Long highway drives automatically clean the DPF by burning off soot. You may notice your engine idling at 1100 RPM before dropping to 800 RPM, along with a slight increase in power.
- Exhaust Self-Cleaning: If the dashboard says “Exhaust self-cleaning,” let the process finish to avoid issues. It means the system is clearing out soot.
- Power Restricted Mode (Limp Mode): If you see a warning and restricted power, you’ve entered limp mode due to failed cleanings. You’ll need a manual regeneration to restore power, indicating that your recent drives were too short for automatic cleaning.
- Manual Regen: If needed, manual regeneration involves idling the engine at 2000 RPM for 10-20 minutes. This cleans the DPF, and after a few drives, the engine light should go off.
Considerations for Diesel Vehicle Owners:
- Driving Habits: If you do mostly short trips, automatic DPF cleaning may not occur, leading to potential issues. Consider alternatives or adjust your driving habits.
- Long Highway Drives: Highway driving is ideal for automatic DPF cleaning, as higher exhaust temperatures keep the filter clear.
- Maintenance: Regular upkeep, including DPF cleaning and using quality diesel, is essential for optimal vehicle performance.
Conclusion:
Understanding DPF maintenance helps ensure your diesel vehicle runs smoothly. If your driving habits suit DPF cleaning requirements, and you commit to proper maintenance, a diesel vehicle with a DPF can be a great choice for minimizing emissions and ensuring performance.
If you find that your Diesel Particulate Filter (DPF) cleans are becoming too frequent or disruptive, especially if you aren’t doing enough highway driving, there’s a solution. The repetitive cleaning might be a sign that your driving conditions aren’t allowing the DPF to complete its automatic regeneration. In this case, visiting a GWM service center can help.
The service center can update your vehicle’s software to the latest version, which extends the number of DPF cleaning attempts to 10 before the car enters limp mode. This update gives the system more opportunities to clear the filter without restricting engine power. It’s an excellent option if your driving mainly involves short trips and urban conditions, as it reduces the inconvenience of frequent DPF maintenance while ensuring the vehicle stays in optimal condition.
