When You Might Need DPF Cleaning

Maintaining a clean Diesel Particulate Filter (DPF) is crucial for diesel owners. The DPF minimises harmful emissions and ensures the seamless operation of your vehicle. However, with regular use over time, the DPF can become clogged. 

In this blog, the experts from Applied Radiators have outlined the warning signs that your vehicle needs DPF cleaning. 

DPF Warning Light

Modern vehicles are equipped with sophisticated onboard diagnostics, and one of the key indicators of DPF issues is the illuminated DPF warning light on your dashboard. If this light appears, it's a clear signal that the DPF is reaching its capacity and needs attention. Ignoring the warning may lead to further complications and potential damage to the DPF system.

Fuel Consumption

A spike in fuel consumption can also be linked to DPF issues. When the filter is clogged, the engine must work harder to expel exhaust gases, resulting in increased fuel consumption. Monitoring your vehicle's fuel efficiency and addressing any unexplained changes promptly can help identify potential DPF concerns.

Smoky Exhaust

A smoky exhaust is often an early indicator that your Diesel Particulate Filter (DPF) may require cleaning. When the DPF becomes clogged with soot and particulate matter, it can lead to incomplete combustion, resulting in visible smoke emissions from the exhaust. If you notice an increase in smoke, particularly a dark or sooty appearance, it's time to consider DPF cleaning.
