Cleaning the DPF yourself (DIY) vs. professional particulate filter cleaning: What you need to know

Cleaning a diesel particulate filter (DPF) is crucial for the optimum performance and longevity of your vehicle. A clogged particulate filter can not only reduce engine performance, but also increase fuel consumption and ultimately cause expensive repairs. But should you clean the particulate filter yourself or should you call in a professional cleaner? In this article, you will find out which method is worthwhile and when, and what risks you should be aware of.

1. Basics of particulate filter cleaning

A diesel particulate filter (DPF) is responsible for filtering harmful soot particles from the exhaust gases. Over time, a considerable amount of soot and ash accumulates in the filter, which can block the exhaust gas flow. This leads to increased exhaust back pressure, which puts a strain on the engine and leads to an increase in fuel consumption. To avoid this, the filter should be cleaned regularly, either by automatic regeneration or manual cleaning.

2. Cleaning the Particle Filter Yourself: Advantages

Many vehicle owners consider cleaning their DPF themselves to save costs. Here are some of the advantages of self-cleaning:

Lower costs

One of the main arguments in favour of self-cleaning is cost efficiency. By purchasing DPF cleaning additives or special DIY kits, the costs can be significantly reduced compared to professional cleaning. These additives usually cost between 20 and 50 euros and can be conveniently purchased at petrol stations or specialist retailers.

Time saving

If you clean the DPF yourself, you save yourself a trip to the workshop and can often complete the process within a few hours. This can be particularly advantageous if the vehicle needs to be ready for use again quickly. Many additives work while the vehicle is in motion, which means no additional downtime is required.

Availability of DIY kits

There are numerous cleaning kits available on the market that are designed for self-cleaning particulate filters. They usually contain a combination of chemicals or compressed air systems that are used to remove soot and ash from the filter. These kits are relatively easy to use and promise a significant improvement in filter performance.

3. Challenges of Cleaning the DPF Yourself

Despite the advantages mentioned, there are considerable challenges with self-cleaning particulate filters:

Incomplete cleaning

Even with high-quality additives or DIY kits, the DPF cannot be completely cleaned. In particular, deep-seated deposits such as ash remain in the filter. This can lead to inadequate filter performance and clog the DPF again more quickly.

Risk of damage

There is a risk of permanent damage to the filter if used incorrectly. Chemical cleaning agents can attack the structure of the filter if overdosed, and improper mechanical processes can damage the filter itself. Such damage is usually irreparable and makes the expensive replacement of the filter necessary.

Not a long-term solution

Although particulate filter self-cleaning can work in the short term, it rarely provides a permanent solution. Regular use of additives can help to clean the filter while driving, but deeper cleaning is required if there is severe blockage or ash build-up.

4. Methods for DIY Particle Filter Cleaning

If you want to clean the particulate filter yourself, you have various options. The simplest method is to use additives that are mixed into the fuel. These additives help to burn off soot during driving. Another method is to remove the filter and clean it manually with special chemicals or compressed air systems. However, these techniques often fail to remove all deposits in the filter, and removal involves significant risks if not carried out professionally.

5. Professional Particle Filter Cleaning: The Advantages

Professional DPF cleaning offers numerous advantages compared to the DIY method:

Deep cleansing

Professional suppliers such as Advanpure use specialised cleaning machines to clean the particle filter thoroughly and gently. These machines, such as the AD5000 and AD7000, make it possible to completely remove deep-seated residues and restore a filter to 95% of its original condition, something that DIY methods cannot begin to achieve.

No damage

While there is a risk of damage with self-cleaning, professional providers use processes that protect the filter. This ensures that the filter structure remains intact and the service life of the filter is not impaired.

Long-term results

In contrast to DIY cleaning, professional DPF cleaning offers more sustainable results. The filter is not only cleaned, but also inspected for possible damage, which helps to prevent future problems. This improves the overall performance of the engine and reduces fuel consumption.

Documentation and warranty

Another advantage is the professional documentation. Many service providers offer comprehensive test reports that document the condition of the filter before and after cleaning. In addition, professional cleaning services often offer guarantees on their work, which provides additional security.

6. Cost Comparison: DIY DPF Cleaning vs. Professional Cleaning

At first glance, self-cleaning of the particulate filter seems cheaper. However, inadequate cleaning or even damage to the filter can quickly increase costs. Professional cleaning of car particulate filters costs €299 at Advanpure, but offers thorough and safe cleaning that extends the service life of the filter and minimises the risk of consequential damage. In the long term, professional cleaning can therefore prove to be more cost-effective.

7. When Professional Cleaning is the Better Option

There are situations in which professional cleaning is clearly preferable, in particular:

• Severe blockages: If the filter is already heavily clogged and the engine indicator light comes on, DIY solutions are often not enough.

• Age of the filter: Older filters that have been in operation for several years often require more thorough cleaning to restore their full functionality.

• Regular maintenance: Professional cleaning should be carried out at least every 100,000 to 150,000 kilometres to ensure that the filter remains operational in the long term.

8. Conclusion: Clean the particulate filter yourself or have it professionally cleaned?

The decision between DIY cleaning and professional cleaning of a particle filter depends on various factors: the available budget, technical expertise and long-term goals for vehicle maintenance.

For tech-savvy people on a budget, the DIY approach may seem like an interesting option at first glance. Cleaning additives or DIY kits can save money in the short term. However, this approach harbours risks: inadequate or improper cleaning can lead to irreparable damage to the filter, which could result in expensive repairs or even the need to replace the filter.

For vehicle owners and workshops who value longevity, safety and professional documentation, thorough and professional cleaning is clearly the better choice. Professional cleaning services offer in-depth and gentle cleaning procedures that ensure the filter’s service life and the vehicle’s performance in the long term.

Especially for fleet operators or workshops that have to regularly service particulate filters, it is worth investing in professional cleaning or even in their own cleaning machines. Companies such as Advanpure offer tailor-made solutions to make the cleaning process efficient and sustainable – a crucial step in maximising the performance and service life of vehicles while minimising the environmental impact.

Ultimately, the choice between DIY or professional depends on your specific requirements. But remember: a clean and well-maintained filter is not only good for vehicle performance, but also for the environment.
