AUTOPROFI DPF / Catalyst Cleaner Spray - 400ml

DPF Catalyst Cleaner

Product properties: The DPF/Catalyst Cleaner dissolves and removes all contamination and soot residues from the particulate filter and the catalyst – no disassembling required. The product eliminates any performance decrease or disruption caused by contaminated particulate filter and catalysts. DPF/Catalyst Cleaner restores the complete function of the diesel particulate filter and catalyst.

The product is also ideal for EGR-valve cleaning.

  • Dissolves and removes contamination in the diesel particulate filter and catalyst.
  • Cleaning without dismantling - Evaporates residue-free

Area of Application: Cleaning of the diesel particulate filter and catalyst.


Attention: The motor must be in hot operating condition. Shake the can well before use! (Approx. 1 min) Dismantle the temperature, pressure sensor or access port on the DPF / catalyst and insert the probe through the opening. Spray the cleaner with the probe inserted into the particulate filter/catalyst in 5-second intervals until the DPF / catalyst is proper filled with the foam. Close the opening after application. When the cleaner has been applied the deposits are released and dispersed in the particulate filter/catalyst. During the normal drive operation the micro-fine dirt particles combust. Restart the regeneration process through a workshop tester. Finally remove the faulty memory entry or delete existing errors. Afterwards perform a test drive consisting of about 20 minutes

DPF/Catalyst Cleaner is usable for all closed particulate filter systems. Check the oil level before cleaning. Oil change is necessary if oil dilution is performed with diesel.

For an optimized regeneration we recommend to add the DPF Clean (43241) into the fuel tank after doing the test drive. For petrol engines we recommend OXICAT (43243).

Consumption: 400 ml is sufficient for one application / diesel particulate filter / catalyst


Vehicle chemical products as a solution suited to the current market value

 Regenerating the diesel particulate filter: avoid clogging and total failure

 If you only use your diesel on short journeys, you risk damaging the diesel particulate filter, which could lead to poor performance and costly repairs. Only preventive measures or a thorough cleaning can prevent the accumulation of ash and soot. Vehicle chemical products offer a good solution for the purpose that suits to the current market value.

 Every day city traffic. Always just from one red traffic light to the next one. Many diesel drivers know this scenario and probably its consequences: eventually it will be there, the yellow light, indicating that the diesel particulate filter (DPF) is full. Occasionally, a few hundred miles are sufficient on short urban journeys, so that the soot particle filter is clogged. Because during the short drive time, the engine does not reach the optimum operating temperature that is needed for the filter to regenerate. The consequences are clearly noticeable: The car accelerates worse, the fuel consumption increases and the engine runs more frequently in the emergency program. In the long term, serious damage and costly repairs may occur. At the same time, the clogging of the diesel particulate filter can be prevented for a car lifelong.

 Avoid soot accumulations, the processes that take place in a diesel particulate filter: In every DPF, there are two substances that accumulate over time. One is soot, the other ashes. To remove the soot, every diesel vehicle – depending on the model and manufacturer – initiates a filter regeneration every few hundred kilometers. However, 500-550 °C (932-1022 °F) are needed in the exhaust gas flow and these temperatures are not reached on short distances. Thus, it does not come to self-cleaning. "So that the failure of the particulate filter can still be avoided. The recommended vehicle chemical solutions: With the help of certain formulations, it is possible to reduce the ignition temperature of the collected soot, so that it is burned on short distances. Anyone who regularly adds such products to the diesel fuel can prevent the DPF from clogging in short-distance operation.

 Remove ash accumulations

 While soot problems are easily avoided, ash accumulations are much more difficult to remove. This substance, which accumulates in the DPF over time, can only be removed by dismantling the particulate filter. The filter must be thoroughly rinsed so that the ash is eliminated in all corners. Here, too, there are vehicle chemical solutions that work thoroughly, but still gently." In addition, these applications are significantly cheaper and suit to the current market value than changing the soot particle filter. The installation of a new DPF is very expensive, the vehicle chemical cleaning is much more reasonably priced.
