WebDPF Cleaning at Halfords Autocentres. If you own a diesel car then chances are you have a Diesel Particulate Filter (DPF). Any diesel engine can be susceptible to soot build-up, especially those mainly driven around town or on short or low speed journeys. DPFs are designed to remove this soot as you drive, but over time they can stop working. WebA Diesel Particulate Filter (DPF) is an important part of a vehicle’s exhaust system, designed to reduce the amount of soot and other particles emitted from the engine. Over time, the DPF can become clogged with these …
