​Reconditioning, cleaning DPF, FAP, SCR, KAT EURO5, EURO6

​The cleaning process consists of six steps:
Step 1 Digital analysis of the condition of the DPF filter cartridge using an endoscope. We check for mechanical damage and the degree of contamination on both sides.
Step 2 Flow test before cleaning. The test is completed with a printout of the result
Step 3 Injection of catalytic fluid to displace accumulated engine oil deposits.
Step 4. Cleaning the DPF with a solution of water and chemistry with a high, pulsed
low-pressure water flow. The use of low water pressure and high flow prevents damage to the DPF. Cleaning the DPF is done in two directions: oppositely and in line with the direction of the exhaust gas flow for maximum results.
Step 5 Emptying of water and drying using hot air at 90 degrees Celsius.
Step 6. Flow test after DPF cleaning. The test is completed with a printout of the result. The customer receiving the reconditioned filter receives documentation of the tests carried out before and after the cleaning process.

When installing a reconditioned DPF in a vehicle, it is recommended to carry out procedures identical to those when installing a new DPF, including the resetting of the DPF particulate indicator.

​A well-executed reconditioning removes 98% of fltra contaminants. A clean filter and good condition of the car (including the condition of the fuel system and turbocharger) will allow the filter to burn out regularly in a standard process.

After professional reconditioning, a DPF can last from 20,000 to even 150,000 km or more. However, it should be borne in mind that regular short runs during which the
engine does not reach its optimum operating temperature can contribute to
the particulate filter to fill up more quickly and shorten its life after regeneration.

To maximise the life of the regenerated DPF, it is recommended to:
Driving longer distances at higher revs on a regular basis, which promotes the filter regeneration process by burning off accumulated particulates.
Maintaining the good condition of the vehicle, including the injection system and turbocharger, which allows optimal fuel combustion and reduces the amount of particulates entering the filter.
Avoiding the use of low-quality fuel and additives that can adversely affect the combustion process and the effectiveness of the DPF.
Regularly servicing the vehicle in accordance with the manufacturer's recommendations.

It is also worth paying attention to signals indicating the need for DPF regeneration, such as relevant messages on the dashboard, a decrease in engine power or increased fuel consumption, and react to them without undue delay in order to avoid more serious damage to the filter and the associated higher repair costs.

​Automatic regeneration: many modern vehicles are equipped with systems that automatically initiate the DPF regeneration process when sensors detect that the filter is full of soot. This process usually takes place while the vehicle is in motion and requires that appropriate operating conditions are maintained, such as driving at a certain speed for a certain period of time.

Forcing regeneration: If automatic regeneration is not possible, e.g. due to frequent short-distance driving, some workshops can offer a forced regeneration service, which is carried out using specialised diagnostic equipment.

Long-distance driving: Regular driving over longer distances at higher revs can help with passive DPF regeneration. The heat generated during such driving can cause burn off the accumulated soot and clean the filter naturally.

Attempting to clean the DPF yourself using homemade methods is risky and can lead to damage to the filter or other vehicle components.

Regular vehicle servicing and avoiding frequent short-distance driving can prevent DPF clogging.

It is always advisable to consult a professional car service before undertaking any DPF regeneration or cleaning to ensure that the chosen method is safe and effective for your particular vehicle.

DPF cleaning is an important part of vehicle maintenance to ensure long-term performance and compliance with emission standards
