Passenger car DPF

Cleaning the diesel particulate filter is much more economical than buying a new one.

Diesel particulate filters of passenger cars are a real challenge when it comes to cleaning. While the filter can usually be removed in utility vehicles and construction machines as a modular system and is freely accessible for cleaning, piping is welded on in front of and behind the filter in passenger cars This makes the filter substrate difficult to access for cleaning.

Oberland Mangold has developed a gentle cleaning process that removes almost all of the embedded soot particles and especially also the ash residues. With this new procedure, it is no longer necessary to remove pipes and parts of the housing in order to make the filter directly accessible for cleaning.

The result can be seen.

  • The original quality is maintained. The high quality original diesel particulate filter is still used.
  • Up to 70% in savings compared to purchasing a new filter.
  • Effectiveness. The cleaned filter is as good as new.
  • Improved NO₂ performance. Less exhaust gas back pressure. Less fuel consumption.
  • Optimal engine output.
  • Efficiency. The filter usually lasts for the vehicle's lifetime.

How long does a diesel particulate filter last in a passenger car?

Between 120,000 km and 180,000 km. The diesel exhaust particles are almost entirely regenerated during normal driving operation. The ash, however, irreversibly accumulates in the filter.
Combustion residue from engine oil, additives and diesel fuel remain in the filter permanently. Over time, the proportion of ash continuously increases.

When driving mostly in cities, it may happen that the embedded carbon-particulate matter can no longer be regenerated via active measures in engine management so that the filter can become clogged with sooty particles.

The engine electronics usually report a full filter in the instrument display. Depending on the model, the vehicle then actually only runs in an emergency programme if the warning signal is ignored.


The following signs are typical of a diesel particulate filter overloaded with soot and ash:

  • Higher fuel consumption
  • Lower engine output
  • Fault / vehicles goes into emergency operation. As a result, often very expensive damage to the engine and turbocharger
  • Consequential damage to the filter due to thermal overload

The workshop usually replaces the original diesel particulate filter with a new filter. This can be expensive, because an original replacement costs between EUR 1,000 and 2,500 depending on the vehicle model. Now there is a much more cost-effective solution:

Revitalise your diesel particulate filter when it starts to weak.
