How to Avoid Problems With Diesel Particulate Filters

Diesel particulate filters (DPFs) have been fitted to diesel-fuel cars for about two decades. If these filters aren’t maintained, there could be serious consequences for your vehicle.

To avoid problems with DPFs, here are some tips to follow:

Regular maintenance

Follow the manufacturer’s recommended maintenance schedule for your vehicle, including regular DPF maintenance. This typically involves periodic inspections and cleaning to prevent excessive soot and ash buildup in the filter.

Quality fuel

Use high-quality diesel fuel with low sulfur content. Poor quality or contaminated fuel can contribute to DPF problems. Additionally, avoid using biodiesel blends above the manufacturer’s recommendations, which can cause filter blockages.

Proper driving habits

Drive your vehicle in a way that helps maintain optimal DPF performance. Avoid frequent short trips or stop-and-go driving, as these conditions can prevent the DPF from reaching the necessary temperature to regenerate properly. Plan longer drives at higher speeds to allow the DPF to heat up and self-clean through the regeneration process.

Avoid idling

Excessive idling can lead to incomplete DPF regeneration and cause soot buildup. If you need to idle your vehicle for an extended period, consider using a DPF regeneration switch (if available) to manually initiate the regeneration process.

Regular DPF regeneration

If your vehicle has an active regeneration system, ensure it works properly. Active regeneration is when the engine increases exhaust temperatures to burn off accumulated soot in the DPF. Monitor warning lights or messages on your dashboard and address any issues promptly.

Clean air intake

Check and clean the air intake system regularly to prevent dirt and debris from entering the engine. A clogged air intake can lead to inefficient combustion and increased soot production, which strain the DPF.

Use DPF cleaning additives

There are DPF cleaning additives available on the market that can help in preventing and reducing soot buildup. Follow the instructions provided by the manufacturer when using these additives.

Consult a professional

If you encounter persistent DPF problems or warning lights indicating DPF issues, it’s best to consult a professional like 30 Minute DPF Clean. They can diagnose the problem accurately and provide the necessary repairs or maintenance.

Remember that following proper maintenance practices and driving habits is crucial for the long-term performance and longevity of your DPF system.
