If you own a diesel vehicle, you probably have a diesel particulate filter (DPF). They are designed to help reduce the level of soot your diesel vehicle emits. Diesel cars are notorious for producing black smoke from the exhaust, which can be dangerous for the environment and your own health.
The filter captures and stores soot but, due to their limited capacity, they need to regularly clean themselves through regeneration. This happens under normal driving conditions. This process removes the build up of soot and reduces harmful exhaust emission.
More often than not, a DPF clean will be able to restore your filter and get it back to as new. With our thorough, eco-friendly cleaning service, we remove up to 98% of soot and ash, which makes a huge difference to your DPF. This can help restore fuel efficiency, as well as eliminating the need to purchase a replacement DPF.
We always recommend a clean over an outright replacement, and believe our cleaning service is the best option to help reduce emissions and keep your costs down too.

To keep your DPF in good shape, you should avoid lots of short journeys in your car, as these can cause blockages. Some oils contain additives that can block your DPF, leading to an anti pollution light appearing on your dash. If your warning light continues to stay on, turns red, or additional DPF lights come on, do not leave it too long before getting it checked out. If you continue to drive with your warning light on you will cause more damage which will become more expensive to fix.
Many garages will offer a DPF cleaning service, but not the full diagnostics examination your vehicle requires. We hear stories all the time of garages simply cleaning a car’s diesel particulate filter without assessing what faults or problems are causing the issues.
Your DPF is built to collect soot. This is normally removed by passive regeneration. However, certain issues can cause an excessive build up and cause the DPF to clog. This then requires cleaning to unclog the filter. It is usually caused by a combination of the issues below:
– Driving a lot of short journeys, or spending a lot of time in traffic
– Not following vehicle’s service schedule
– Wrong engine oil specifications
– Consistently driving on less than 1⁄4 tank of fuel
– Excessive vehicle mileage or worn engine, causing increased oil burn
– Engine faults or engine management lights
– Cheap or supermarket fuel
There are often tell tale signs that your vehicle may be in need of a DPF clean. If you recognise any of the issues below, you should book in for a diagnostics check. We can then advise you if your vehicle is in need of a DPF clean.
– Warning lights on dash
– Vehicle in limp/derate mode
– Poor acceleration
– MPG lower than it used to be
– Oil level rising
– Excessive vehicle smoke
– High fuel consumption
– Strong diesel smell.
Ignoring these warning signs can cause oil dilution, which can cause damage to your engine and turbo. By addressing these issues early, you reduce your risk of needing a replacement DPF or further costly repairs.

DPF cleaning is one of the most commonly requested services we offer, as it is a more cost effective alternative to a replacement. However, you must ensure that you use a garage that offers a thorough clean and assess the health of the diesel particulate filter in the process. We have invested in the latest technology to offer a professional deep clean which will leave your car safer and reduce the need for bigger works in the future.
We cover a wide range of vehicles including cars, vans, HGVs and commercials. We also offer discounts for trade or fleet work. We are also specialists in DPF cleaning for agricultural and plant equipment as well as boats and marine engines.
If you approach our garage after seeing a dash fault light, noticing your vehicle in limp mode or a persistent smell of diesel, a DPF clean may be in order. Our in depth process means you can be sure your vehicle will be given a DPF clean using our latest eco-friendly technology.
Below is a step by step explainer of our process:
Sometimes a full clean isn’t necessary, and we can regenerate your DPF without needing to remove it from your vehicle. This is called a static regen. This is only possible in some circumstances, when initiated with our diagnostics tool. If your DPF is found to be over clogged, a full removal and clean will be required. With both services, we offer every customer advice to keep your DPF clean and reduce soot buildup.
