If you own a diesel car, you almost certainly have a diesel particulate filter, otherwise commonly referred to as a DPF. However, you may not know exactly what this is or how to maintain it. But, we are sure you’ve read about it in the news, heard horror stories about it from your friends, or maybe you’ve had problems with yours already, and had it cleaned by our DPF Cleaning Experts in Petersfield already. 

Diesel particulate filters have been fitted to diesel cars for over 20 years now, but if not properly maintained, or if it’s tampered with there could be serious consequences for your car and your pocket.

So, let’s explain exactly what they are, what they do, why you need them and how to look after them. So hopefully you wont have troubles that mean you have to call our DPF cleaning experts in Petersfield, to get you back on the road.

What Is A Diesel Particulate Filter?

A Diesel Particulate Filter (DPF) is simply a filter that captures and stores exhaust soot that’s generated in the combustion process, in order to reduce emissions from diesel cars. Have you noticed how clean the air is in cities in recent years, compared to a few years ago?

But because diesel particulate filters only have a finite capacity, this trapped soot periodically has to be emptied or 'burned off' to regenerate the DPF.

This regeneration process cleanly burns off the excess soot deposited in the filter, reducing harmful exhaust emissions and helps to reduce the black smoke associated with diesel vehicles, particularly when accelerating.

Sometimes this regeneration process fails and your DPF will need a helping hand to remove the soot and ash that’s blocked it. At AutoMatt, the DPF cleaning experts in Petersfield, we have invested in the special equipment needed to clean the DPF, without having to replace the diesel particulate filter, which is often costly.

Is It Illegal To Remove A Diesel Particulate Filter?

Yes, it is illegal. Owners face fines if caught (up to £1,000 for cars and £2,500 for vans) and removing a DPF can also invalidate your car insurance policy. Because of this, the presence and completeness of your DPF is also a fail or pass on your MOT test.

How Do I Tell If My Diesel Particulate Filter Is Blocked?

If the DPF is becoming clogged with soot or a fault develops in the system, a warning light will appear on the dashboard to let you know something has gone wrong. Don’t delay in contacting us at AutoMatt if you see this warning lamp, as generally speaking, once the warning lamp is illuminated, total breakdown is not far away! Don't worry though, AutoMatt's DPF cleaning experts in Petersfield, are on hand to determine what's caused this warning lamp to come on.

What Causes A Diesel Particulate Filter Blockage?

Short journeys at low speeds are the prime cause of blocked diesel particulate filters. This is why car makers these days, often recommend a petrol engined vehicle for city drivers instead of a diesel. Unlike a few years ago, when there were many mis-sold diesel engined cars sold.

There Are Many Other Things That Cause A DPF To Block:

Poor servicing, and extended service intervals all put unnecessary stress on a DPF. A diesel particulate filter on a poorly serviced car may fail sooner than a well maintained one. Generally they should last for at least 100,000 miles, having your DPF periodically cleaned by our DPF cleaning experts in Petersfield can drastically increase this figure.

It’s important you use the right type of oil as well, a diesel engine with a diesel particulate filter needs a special engine oil, referred to as ‘Low Saps’ oil. Unfortunately, you can no longer top your engine oil up with cheap oil from Tesco, unless you want problems in the future.

Performance modifications can damage a diesel particulate filter, as can using low-quality fuel.

Do you run your fuel tank always on empty? Only topping up with a tenners worth of fuel? If so, many cars will not enter into the regeneration process, which will eventually cause a breakdown.

How Do I Maintain A Diesel Particulate Filter?

The best way to maintain a DPF is to make sure it’s fully able to regenerate itself when it’s full of soot (when the warning light appears).

There are two types of regeneration: passive and active.

Passive regeneration occurs when the car is running at speed on long motorway journeys which allows the exhaust temperature to increase to a higher level and cleanly burn off the excess soot in the filter automatically.

Active regeneration means extra fuel is injected into the exhaust manifold by the ECU to raise the temperature of the DPF and burn off the stored soot.

Problems can still occur however, if the journey is too short, as the regeneration process may not complete fully. In this case the warning light will continue to show that there is a problem with the DPF.

Some garages can clean blocked DPFs, in a process called forced regeneration. However, at our workshop in Petersfield our DPF cleaning experts prefer a softer approach to unblocking a diesel particulate filter. We have a special DPF cleaning machine that gently removes the blockages from the DPF on your vehicle without having to remove it, which is cost effective.

Do I Need A Diesel Particulate Filter To Pass The MOT?

A diesel particulate filter check has been part of the MOT test since February 2014. If a diesel particulate filter has been removed or modified, the car will fail its MOT test. Removing the DPF will cause the warning light on the dashboard to glow, this is also an MOT failure, as no dashboard warning lights should remain on during the MOT test.

What Is The Cost Of A New Diesel Particulate Filter?

Diesel particulate filters are very expensive! So, having one of our DPF cleaning experts clean your diesel particulate filter at our Petersfield workshop is always preferable. Good quality DPFs can cost over £1,000 and often over £3,500! It’s been our experience that fitting a ‘cheap’ replacement DPF, is often a false economy. They frequently cause further costly problems down the line that could have been avoided.

As cars age, the cost of the replacement DPF could be more than the value of the car, and it is older, higher mileage cars, that are most likely to require a new DPF. So give us a call on 01730 858120 to find out how we can help keep you on the road.

Modern diesel car owners need to be conscious of the importance of maintaining their diesel particulate filter through good driving habits and best practices.
