Particle filter cleaning

If you have a diesel vehicle, it is important to have the diesel particulate filter (DPF) cleaned on time. A dirty or full DPF can reduce your vehicle’s performance and can even lead to breakdowns and costly repairs. Fortunately, there is a solution: cleaning the diesel particulate filter.

A particulate filter or particle filter is a filter installed in a car’s exhaust system that helps remove soot particles/particles from the exhaust. Particles are small pieces of dust floating in the exhaust. They can come from a variety of sources, such as gasoline, diesel and even brake pads.

When these particles enter the particle filter, they are trapped by a honeycomb filter ceramic with microscopic pores. Over time, the particulate filter becomes clogged with particles. The engine then initiates a regeneration phase and the particles are burned. At some point, the particulate filter becomes saturated with ash, among other things, and must be cleaned or replaced so that the engine can get rid of its exhaust.

Cleaning the original particulate filter is important to maintain top performance and prevent problems. There are several ways to clean the filter, but the most effective method is professional machine cleaning. This ensures that the filter is thoroughly cleaned and that the micropores become free again, without damaging the filter ceramics.

For this purpose, a special cleaning machine is used, originating from Germany, which guarantees the best possible cleaning in a safe, sustainable and environmentally friendly way. The cleaning method has been scientifically tested and is highly regarded in several German trade journals. It is approved by Iso 9001, TUV and Dekra.

The cost of cleaning is 275.00 euros per filter.

The benefits of professional cleaning are

  • Behoud van je eigen originele af-fabriek roetfilter
  • Gegarandeerde verwijdering van al het roet en as
  • Het filterkeramiek wordt niet aangetast
  • Geen kalkresten in het filterkeramiek na reiniging
  • Geschikt voor Euro 6D-roetfilters
  • Filter binnen 2 uur gereinigd
  • Reiniging volledig gedocumenteerd
  • Uitgebreid reinigingsprotocol voor en na reiniging
  • De filterbehuizing waarin het filter is geperst blijft onaangetast
  • 6 maanden reinigingsgarantie*

Note that from Jan. 1, 2023, the MOT for diesels has been expanded to include an exhaust particle counter that can count more than one million particles per cubic centimeter. Broken particulate filters or cheap imitation particulate filters are detected by this. This is because an original factory particulate filter is emissions-tested and often contains expensive precious metals to meet emissions values, while aftermarket/imitation particulate filters do not possess this and therefore cost a fraction of an original filter and are now falling through en masse.

Why Clean Soot Filter?

Saleem - TuneX

A particulate filter is designed to reduce harmful exhaust emissions and prevent soot particles from entering the air. Over time, these soot particles can accumulate and reduce the filter’s performance, which can affect the car’s performance. Regular cleaning of the particulate filter can help prevent these problems and ensure that the car continues to function optimally.

Why this technique

In today’s market, there are many different ways to clean a particulate filter. However, not all methods are equally effective.

Some methods use a chemical injected into the filter through a pressure or lambda sensor. This chemical increases the regeneration temperature to convert the unburned soot into ash. However, this is not a real cleaning, but only a temporary solution. This is because the ash present in the filter cannot burn twice and thus remains in the filter. In addition, there is a chance that the filter ceramics could melt due to the uncontrolled temperature rise during regeneration, which could lead to disapproval of the MOT particle counter during a road trip.

Grinding open the particulate filter and burning it out in an oven is also not recommended. First, soot filters are pressed into the exhaust part ex-factory to avoid any
cause leakage past the filter. Once the filter is grinded open and later reinstalled and the particulate filter is welded back in place, under
pressure always be leakage along the filter element (see photo). Moreover, the welding arc reaches a temperature of 14000°C during welding, while the filter ceramic is designed for temperatures up to 800°C. Welding on the filter housing is also strongly discouraged.

A professional and durable machine cleaning prevents these problems and keeps your original particulate filter in top condition.

*If the particulate filter becomes full again within 6 months, we will re-clean it once free of charge, excluding any de/mounting costs. However, it is necessary to have the engine examined to find out why the filter became full again. If a filter fills up quickly, it means the engine is producing too many emissions.
