The DPF traps soot particles from the exhaust gases and periodically burns them off in a process called regeneration. This happens automatically when the exhaust gets hot enough — typically during longer, faster drives — converting soot into ash and reducing harmful emissions.

Proper DPF maintenance prevents blockages, maintains engine performance, improves fuel efficiency, and ensures compliance with emissions regulations. A damaged (as illustrated here), neglected or blocked DPF can trigger warning lights, cause reduced power, and lead to costly repairs or MOT failures.

At Soul Garages we offer expert advice and servicing for diesel particulate filters, and can help you avoid damage before it occurs.
