DPF cleaning is the process of restoring your diesel particulate filter to its original condition. This includes testing and thoroughly cleaning the DPF to eliminate ash, soot and carbon buildup, ensuring your vehicle runs at peak performance and efficiency.

Indicators that your DPF needs cleaning include a loss of power, the DPF warning light turning on, activation of limp mode, failed regeneration attempts, a strong smell of diesel, excessive exhaust smoke, rising oil levels and higher fuel consumption.

Yes. Cleaning your DPF is far more affordable than a full replacement. It provides a cost-effective way to extend the life of your current filter, saving you money on expensive replacements and offering long-term value.

Opting to refurbish your DPF is an eco-friendly choice as it helps reduce the demand for new filter production and minimises waste. By refurbishing, you play a part in conserving resources and lowering environmental impact, contributing to a more sustainable future.

At National DPF Cleaning, we offer both an on-car DPF clean and an off-car DPF clean. On-car cleaning involves running a special chemical through the filter to remove soot particles. Off-car cleaning is more thorough and uses specialist machinery to remove up to 98% of carbon, soot, and ash particles.
