DPF Cleaning in Bridport
The Importance of Looking After Your Diesel Engine
Maintaining a diesel vehicle comes with unique responsibilities, and one critical task that often goes overlooked is cleaning the Diesel Particulate Filter (DPF). This is a crucial component in reducing harmful emissions, making it essential for your vehicle’s performance, efficiency, and compliance with environmental regulations. Regular DPF cleaning, alongside routine car servicing, can save you from costly repairs and ensure your vehicle runs at its best.
Bridport-based Central Motors is on hand to provide a complete maintenance program for diesel and petrol engines. We specialise in vehicle servicing, MOT testing, and general garage services, including new exhausts, clutches and brake replacements. We’re the team to call if you’re looking for reliable and experienced garage mechanics to look after your vehicle.
What is a DPF, and Why Does It Need Cleaning?
A diesel particulate filter (DPF) is designed for diesel engines to capture soot and particulate matter from exhaust gases before they are released into the environment. Over time, the DPF collects a significant amount of soot and ash, which can lead to blockages. A clogged DPF can negatively impact your engine’s performance, increase fuel consumption, and even cause your vehicle to fail its MOT test.
DPF cleaning helps remove this buildup, restoring the filter’s efficiency and keeping your engine in optimal condition. Our garage mechanics recommend you have this carried out during routine car servicing.


Signs Your DPF Needs Cleaning
Recognising the warning signs of a blocked DPF can save you time and money.
- Warning Lights: Many vehicles have a DPF warning light that illuminates when the filter is clogged. If this light comes on, act quickly to avoid further issues.
- Reduced Performance: A blocked DPF can cause your engine to lose power and respond sluggishly during acceleration.
- Increased Fuel Consumption: A clogged filter forces your engine to work harder, leading to higher fuel costs.
- Excessive Smoke: If you notice more smoke coming from your exhaust than usual, it may be a sign your DPF needs attention.
Ignoring these signs can lead to more severe problems, such as damage to the filter or even the engine itself.
How Does DPF Cleaning Work?
There are several methods to clean a DPF, ranging from natural processes to professional services:
Passive Regeneration
This occurs naturally when your vehicle operates at high speeds for an extended period, such as on a motorway. High exhaust temperatures burn off soot in the DPF, keeping it clean. This is why diesel vehicles are better suited for long-distance driving rather than short city trips.
Active Regeneration
In active regeneration, your vehicle injects extra fuel to raise the exhaust temperature and burn off soot. While this process is automatic, it requires certain driving conditions to be effective, such as maintaining higher speeds for a prolonged time.
Professional Cleaning
If your DPF becomes heavily clogged, professional cleaning may be necessary. Our reliable garage can assess your DPF’s condition and recommend the best cleaning method. Including this service in your regular car servicing schedule ensures your DPF remains in top shape.
MOT testing specialists, Central Motors can also use this opportunity to fit new clutches, brakes, and exhausts for our growing number of clients in and around Bridport.
The Importance of DPF Cleaning in Car Maintenance
Regular DPF cleaning doesn’t just keep your engine running smoothly—it also helps with:
- MOT Testing Compliance: A blocked DPF can result in failed emissions tests during your MOT, making cleaning essential for passing.
- Environmental Responsibility: A clean DPF reduces harmful emissions, helping you do your part for the environment.
- Cost Savings: Neglecting a clogged DPF can lead to expensive repairs or even the need for a complete replacement.
- Longevity of Other Components: When the DPF is clogged, essential components can wear prematurely due to insufficient efficiency.
