Particle filter cleaning: Efficient, economical and clean

Regular cleaning of the diesel particulate filter (DPF) is crucial for the long-term performance of diesel vehicles. A clogged DPF can lead to significant performance losses, increased fuel consumption and even serious engine damage. TUNAP offers pioneering and economical solutions for efficient DPF cleaning that benefit workshops and drivers alike.


What is the diesel particulate filter (DPF)?

The diesel particulate filter, also known as the soot particle filter or DPF for short, is an indispensable component in the exhaust system of diesel vehicles. Its main task is to filter harmful soot particles from the exhaust gases before they are released into the environment. The DPF collects these particles and eliminates them through combustion under specific operating conditions in order to reduce emissions and comply with environmental regulations.

The functioning of the DPF depends on various factors, such as vehicle conditions, driving cycles and the specific exhaust concept of the respective car manufacturer. However, an overloaded or blocked DPF can cause problems that not only affect the performance and efficiency of the vehicle, but can also lead to costly repairs.

Reinigung & Regeneration DPF

Our cleaning fluid and flushing solution support the subsequent regeneration of the DPF by converting soot deposits into CO₂.

Importance of DPF cleaning

Regular and effective cleaning of the diesel particulate filter is crucial to maintain the vehicle's performance and avoid expensive repairs. A blocked DPF can lead to reduced engine performance, increased fuel consumption and impaired throttle response. Over time, it can even cause serious engine damage.

Traditionally, a blocked DPF is treated by replacement, but this comes at a significant cost. New DPFs can cost between €1,000 and €6,000, in addition to the expense of longer workshop visits and replacement vehicles.

In contrast, cleaning the particulate filter is a cost-effective and time-efficient alternative. Specialized cleaning fluids and processes can effectively remove soot and ash particles, restore the functionality of the DPF and extend its life.

Solutions for DPF cleaning

TUNAP has established itself as a leading provider in the field of DPF cleaning technology. With a comprehensive understanding of the challenges of clogged particulate filters, we have developed special cleaning products and processes that enable efficient and safe cleaning of the DPF:

  • Our cleaning kit consists of a diesel particulate filter cleaning fluid and a rinsing solution. These specially developed products dissolve soot and ash deposits extremely effectively and are non-flammable and metal-free, which ensures they are safe to use.
  • We have developed a special pressure cup gun for optimum application of the cleaning fluid. This enables precise and effective cleaning of the DPF without having to remove the filter.
  • Our patented cleaning methods offer a fast and efficient solution for restoring the functionality of the DPF. The technology is approved by leading car manufacturers and has proven itself in over a million applications.
  • In addition to the cleaning solution, we also offer products to prevent blockages in the DPF. These help to reduce the burn-off temperature of the soot in the particulate filter and extend the regeneration intervals.

With our solutions, we support workshops, car dealerships and drivers in optimizing the service life and performance of their diesel particulate filters, lowering costs and reducing downtimes.

Frequently asked questions (FAQs)

The frequency of DPF cleaning depends on various factors, such as driving style, driving conditions and vehicle type. It is generally recommended to have the DPF cleaned every 150,000 to 200,000 kilometers or when there are signs of clogging.

Changing a particulate filter is usually associated with high costs, effort and a longer duration. In contrast, the TUNAP process makes it possible to clean the particulate filter while it is installed. This process takes about 2 hours and is available at a price of 200 to 400 EUR, tested and certified by TÜV and VERT®.

With the help of TUNAP's cleaning technology, cleaning can usually be completed within a day, depending on the utilization of the workshop and the condition of the filter.

Yes, cleaning and reusing a DPF is an environmentally friendly choice as it reduces the need to manufacture and dispose of replacement filters.

Neglected DPF cleaning can lead to reduced engine performance, increased fuel consumption and ultimately to serious engine damage.
