DFP Assessment
DPF Cleaning & Diagnostics Service
At CJ Auto Service Ltd, we understand that a Diesel Particulate Filter (DPF) rarely blocks on its own. Most blockages are caused by underlying faults, which we identify and resolve before cleaning to prevent recurring issues.
A fully functioning DPF is essential for your vehicle’s performance and legal compliance. Removing a faulty DPF can lead to fines of up to £1000 for cars and £2500 for vans, as well as invalidating your insurance.
As accredited members of The DPF Doctor network, we are part of a trusted group of DPF specialists. With over 35 years of combined experience, we diagnose and fix DPF problems efficiently.
We offer competitive pricing without compromising quality, and some minor repairs are included in the assessment fee.

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.

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.

Definitely! 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 replacements
- 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.
