What to do in a situation where it is not possible to clean the DPF?
DPF is a soot particle filter and is mandatory for all modern diesel cars since 2008 in order to meet the EURO 4 norm. In addition to the DPF filter, there is often a DOC catalyst in the same housing, especially in vehicles with EURO 5 and 6 engines..
In the last 10 years, in order to improve the quality of exhaust gases, a system for reducing nitrogen oxides has been installed on cars with a diesel engine.
This system works by injecting the AdBlue additive into the exhaust gases, enabling their additional purification when passing through the SCR catalyst. Exhaust gas processing systems on modern vehicles are very complex and sensitive, so any irregularity in the operation of the engine can quickly lead to problems with clogging of the DPF filter or even damage to its delicate honeycomb or catalyst.
Problems with DPF filters
The most common problems, in addition to their clogging with soot and ash particles, are mechanical damage to DPF honeycombs and loss of catalytic properties.
Malfunctioning components such as nozzles or turbochargers can damage the sensitive ceramic honeycomb. Forced regeneration when the filter is clogged can also cause damage, and unprofessional treatment with various acids and washing under high pressure completely lose the catalytic properties of this component. In short, the filter is washed, but in such a way that it loses its basic function, which is the collection and burning of soot particles.
What solutions exist on the market?
New original DPF filters are of high quality but expensive, and replacement filters that can be obtained in the after market are often of poor quality and cause problems immediately after installation because service technicians cannot correct the error.
As a third option, some vehicle owners decide to remove the DPF filter. This third can be understood when it comes to older vehicles, but the problem is that the DPF system goes off even on relatively new cars, which significantly reduces the value of the vehicle and makes it impossible to pass the technical inspection according to the new standards.
Which solution is the most optimal?
For owners of used cars whose DPF filter or catalyst is damaged, and who cannot allocate several thousand euros for new original components, but at the same time do not want to turn off the exhaust gas processing systems by software and thus remain without the EURO standard, a new model has recently appeared on the market. a new option that represents a compromise between price and environmental standards.
In the company Magnum, DPF service from Zrenjanin, based on EU practice that has existed for more than 10 years, it is now possible to repair old DPF filters and catalysts
This company, which has been successfully producing and repairing exhaust systems for 13 years, has been developing a repair service for damaged DPF filters and catalysts for the last two years, offering an efficient and affordable solution for car owners.
According to the owner of the service, Stojan Materić, by replacing only the catalytic element (honeycomb), savings are possible, and the quality is like that of a new part.
Repairs are carried out with the use of honeycomb (substrate) of original dimensions and proven quality. In short, only what is damaged is changed and thus we get a fully functional DPF or catalytic converter at a reasonable price.
Quality, guarantee and prices
Catalysts have been successfully repaired in this service for 6 years, and for the last 2 years it has also been done with DPF filters. The warranty for repairs is 25 months or 50,000 kilometers.
As they say, they already have numerous satisfied clients who have traveled over 100,000 km after the repair of parts of the exhaust gas treatment system. In the Magnum company, they emphasize that the quality of service is a priority, which is why they use only high-quality components, which is somewhat reflected in the repair price.
The price of repairing a DPF filter or catalyst depends on the type of vehicle and the corresponding EURO standard. The range of prices for repairs varies from 25,000 to 85,000 dinars per repaired component, depending on the complexity and specificity of the vehicle.
