A blocked Diesel Particulate Filter (DPF) is one of the most common causes of warning lights and reduced performance in diesel vehicles. Auto Clinics High Wycombe offer professional DPF cleaning services that restore your filter to optimal condition without the cost of replacement.
A Diesel Particulate Filter (DPF) is a device fitted to the exhaust system of diesel vehicles to capture and store soot particles, preventing them from being released into the atmosphere. Over time, particularly on vehicles used primarily for short journeys, the DPF can become blocked with accumulated soot and ash.
Common symptoms of a blocked DPF include an illuminated DPF warning light on your dashboard, reduced engine power or limp mode, increased fuel consumption, a strong smell from the exhaust, and in severe cases the engine refusing to start. If you notice any of these symptoms, have your DPF inspected promptly to avoid more costly damage.
We carry out professional DPF cleaning using specialist equipment that safely removes accumulated soot and ash from the filter. Our process includes a diagnostic check to confirm the blockage level, a chemical cleaning treatment, a forced regeneration cycle to burn off remaining deposits, and a post-clean diagnostic check to confirm the filter is functioning correctly.
A professional DPF clean is significantly cheaper than replacing the filter entirely. In most cases, a thorough clean restores the DPF to near-original efficiency. We'll advise you honestly if the filter is too far gone to clean and replacement is the better option.
DPFs block most commonly in vehicles used for short, low-speed journeys that don't allow the filter to reach the temperature needed for passive regeneration. We can advise you on driving habits and maintenance that will help keep your DPF clear.
