A Diesel Particulate Filter (DPF) rarely blocks on its own.

In most cases, the DPF becomes blocked due to a problem or fault elsewhere, and it is imperative that we find and resolve this issue first.

Carrying out a DPF clean without doing so will almost certainly lead to your DPF becoming blocked again.

Once we’ve carried out our assessment, we will identify the root cause(s) of your DPF problems and inform you of any necessary repairs that are required.

The cost of some minor repairs will be covered in the DPF assessment fee.

Here at CJ Auto, we offer some of the most competitive prices in Warrington – but this isn’t to say that the quality of our service is compromised.

We always go above and beyond for our customers.

The importance of our DPF assessments

A fully functioning DPF is crucial, so where one is giving you issues, the first step is to discover the root cause.

If your DPF is faulty, you might think it’s as simple as just removing it altogether but doing so could land you a hefty fine of up to £1000, with penalties rising as high as £2,500 for van drivers.

Removing the DPF from your vehicle could also invalidate your car insurance, so it goes without saying that this isn’t the quick fix you think it is.

Whether it’s a systems fault or a mechanical issue, our advanced assessment is designed to get to the bottom of the problem, with our sole aim being to provide a first-time fix – saving you time, money and hassle.

It’s important to note that we do offer a DPF cleaning service where necessary, but if your DPF is faulty due to a block or another issue, an assessment must be carried out first.

In many cases, we can restore your DPF without needing to clean it, getting you back up and running in no time.

Frequently Asked Questions

Diesel Particulate Filter, or DPF cleaning, involves the use of specialist technology and chemicals to reduce soot emissions generated by your engine.
Usually, the filter removes soot automatically by using passive regeneration, but our cleaning service here at CJ Auto removes the excess that might be preventing regeneration from taking place.
Our experts will inspect your filter to assess the scale of the problem and complete a sophisticated cleaning and drying procedure to remove excess soot and ash – testing your vehicle afterwards to ensure the procedure was successful.

There are many tell-tale signs that your DPF is in need of a clean.
When the filter becomes clogged with soot or faulty in any way, you’ll usually be alerted by a light on your dashboard.
The emission of black soot is another sign that you need to have your filter looked at, as well as your oil and fuel consumption levels increasing.
If you’ve been experiencing any of these issues, don’t hesitate to make a booking with our experts.
Give us a call on 01925 589 066 or email reception@cjautoservice.co.uk to arrange a convenient date and time.

Your DPF is more susceptible to blockages when you take a number of short journeys whilst driving at slow speeds. However, in most cases a blocked DPF is a symptom of another problem, like a faulty DPF sensor, incorrect engine oil or a failing turbo.
Its important to note that a blocked DPF is usually just a symptom of a problem elsewhere in your engine, rather than a fault with the filter itself.
Checks and cleaning services should be carried out by a professional, to ensure the job is done properly and to steer clear of any nasty issues further down the line.

If your DPF is compromised in any way, the results can be devastating for your vehicle. There are many reasons why you should have it checked and cleaned regularly, including:

• Better fuel economy and engine performance

The DPF is part of your vehicle’s engine exhaust system.

Even if it’s only partially clogged, it will increase back pressure in your engine, which will negatively affect your fuel economy.

Keeping your filter clean will help your engine run as smoothly as possible.

• Avoid pricey

Diesel particulate filters don’t come cheap.

A new one can set you back anywhere between £1,000 and £3,500, but the best way to avoid these expenses is to have it checked and cleaned regularly by a professional.

• Increased resale value
It’s no secret that a well-maintained vehicle can put an extra few hundred pounds in your wallet when it’s time to sell up, and having your DPF filter cleaned regularly will help to keep your car or van in the best shape.

Generally, a diesel particulate filter should last you for around 100,000 miles, but this can vary depending on how well-maintained it is.
Ensuring the optimum health of your DPF is key if you want maximum longevity, and neglecting your filter will, of course, result in you needing a replacement much sooner.
To keep your filter in tip-top condition, it must be emptied regularly.
This requires no work on your part, as it will happen naturally in a process known as ‘regeneration’ – where the soot that’s been collected is burnt off when your engine reaches a specific temperature.
Ash will be left behind during this process, which is where DPF cleaning comes in and why it’s so important.
The type of fuel you use also plays a massive part in the overall health of your vehicle’s filter.
If you take good care of your filter, it can last you for up to 150,000 miles before you need to think about getting a replacement.
