DPF Regeneration – FAQ
What is a DPF?
The Diesel Particulate Filter (DPF) is designed to capture soot and reduce harmful emissions from your vehicle’s exhaust system. It helps keep your car cleaner and compliant with emissions regulations.
What is DPF regeneration?
DPF regeneration is the process of burning off soot trapped inside the filter. At Pit-air Motors, we use specialist equipment to safely and effectively regenerate or clean your DPF.
How do I know if my DPF is blocked?
Common signs include dashboard warning lights, reduced engine performance, poor fuel economy, and increased exhaust smoke. If you notice any of these symptoms in Croydon, bring your vehicle in for a diagnostic check.
Can I clean my DPF myself?
We don’t recommend it. Proper DPF cleaning requires professional tools and controlled procedures. DIY attempts can damage the filter or cause further engine issues.
How often does DPF regeneration need to be done?
It depends on your driving habits. Short city trips cause faster soot buildup, while longer motorway journeys allow the car to perform automatic self-regeneration. If you mainly drive around Croydon, more frequent manual regeneration may be needed.
What happens if I ignore a blocked DPF?
A badly blocked DPF can cause your car to enter limp mode, fail its MOT test, or even lead to serious engine damage. Early intervention is always cheaper and safer.
Is DPF regeneration an MOT requirement?
Yes. A missing, blocked, or faulty DPF will result in an MOT failure. Keeping the filter clean is essential for both legal compliance and vehicle performance.
How long does DPF cleaning take?
Most DPF regeneration or deep cleaning procedures take two to four hours, depending on the level of blockage and the vehicle type.
