ROA² technology


  • Even more powerful cleaning formula based on ROA² technology

  • Deposits on injectors are broken down and cleaned away

  • Ensures a consistent injection spray, smooth idling, reduced fuel consumption and lower emissions

  • ROA² level 3: The cleaning action is powerful enough to remove contamination that has accumulated over as many as 80,000 kilometres


    • Properties


  • Enables the injectors to be cleaned directly

  • The injectors do not need to be removed before use

  • Breaks down and removes resin residues and deposits

  • Excellent cleaning performance around the inlet valve of aspirated engines

  • Ensures an even injection spray, smooth idling and reduced fuel consumption

  • Reduces emission values compared to when the system is not clean


    • Application area


  • For cleaning petrol injection systems

  • In cases of poor fuel quality

  • In cases of malfunctioning, e.g. rough idling

  • In cases of excessive fuel consumption

  • Prior to all adjustment work and emissions tests

  • In cases of poor engine performance

  • For fuel injection system faults caused by contamination

  • For fuel-related contamination in high-pressure pumps


    • Instructions


    Special tool TUNAP 13310 ICM 2020 must be used to allow the system to be cleaned without dismantling the injectors. Refer to the operating instructions before use.
