Symptoms and Problems

An overloaded particle filter can lead to various issues, including:

  • Loss of Engine Power
  • Increased Fuel Consumption
  • Suboptimal Throttle Response

When to Clean the Particulate Filter

Cleaning is necessary when:

  • Full Loading without Regeneration: If the DPF cannot regenerate itself due to excessive loading.
  • Fully Loaded Filter with Intact Components: When the filter is fully loaded, but the component itself is still intact.

Result of DPF Cleaning

Our cleaning fluid and rinsing solution enable:

  • Subsequent Regeneration: Soot deposits are burned to CO₂ in a subsequent regeneration, without additional environmental burden.
  • Fully Functional Filter: The particle filter is restored to full functionality after cleaning.

Application and Effect

Instead of replacing the DPF, our cleaning process involves:

  • Dissolving Deposits: The cleaning fluid effectively dissolves deposits on the component.
  • Complete Particle Removal: The neutralization solution ensures the thorough removal of particles, preventing future issues.


DPF may become blocked due to various reasons. The most common culprits include:

  • Sooty/dirty injectors
  • Dirty Exhaust Gas Recirculation (EGR) system
  • Fluctuating fuel quality
  • Unfavorable driving profile: The vehicle is not driven on long journeys, leading to insufficient filter regeneration.
  • Cleaning the DPF in situ with TUNAP diesel particulate filter cleaning.
  • Removing the DPF for thorough cleaning

DPF cleaned with the TUNAP system are comparable to new filters. To ensure prolonged DPF functionality, address and eliminate the root causes of blockage, or the filter may clog again.

The TUNAP DPF cleaning fluid is non-flammable.

The VERT® Association verifies and recommends the effectiveness of the TUNAP DPF regeneration process

Generally, DPF replacement is necessary only if components are defective. When the filter is blocked or sooty, cleaning is often sufficient.

SCR and NSC catalysts, primarily in newer vehicles (mainly EURO 6), focus on reducing nitrogen oxide (NOx) emissions and are not directly linked to DPF cleaning. During DPF cleaning, they only come into contact with the TUNAP cleaning fluid during discharge.

To prevent renewed DPF blockage, address the root causes:

  • microflex 989 Injector Direct Cleaner: Cleans dirty injectors from fuel-related sediment.
  • microflex 925/926 EGR System Cleaner: XFoam technology dissolves stubborn contamination in vehicle intake and exhaust systems.
  • Regular addition of microflex 984 Injector Direct Protection can prevent injector contamination.

Drive longer distances, preferably on motorways, with more strain on the engine. Regular use of the micrologic 184 Particulate Filter System Ingredient can also prevent blocked DPFs, even with unfavorable driving profiles.

During TUNAP DPF regeneration, soot deposits are dissolved and burned to form CO₂ during normal filter regeneration. This process has no additional environmental impact, preventing damage associated with manufacturing new filters, including raw material extraction and high energy consumption
