Forced regeneration
When the filter holds mostly soot.
With a device we burn off the soot in the filter. The filter stays on the car.
DPF cleaning
The DPF light is on or the car has lost power? First we find why the filter fills up, then we clean it.
Send us the make, model, year and mileage.
We work in several cities in Serbia. Tell us your city.
BeforeAfterSigns that the DPF is full
The car has lost power Often with the engine light.
The oil level is rising There may be diesel in the oil.
First we check how full the filter is and what fills it. Only then do we say whether a regeneration, cleaning or replacement is enough. Tell us which sign you see and send the make, model, year and mileage.
Regeneration, cleaning or replacement
Which one is for your car, we tell you after the check.
Cleaning a removed filter
When there is a lot of ash. Neither driving nor regeneration removes it.
We remove the filter, clean it off the car and refit it.
Replacement
When the filter is cracked or melted, or cleaning does not help.
We fit a new filter.
How much does DPF cleaning cost
You pay only for what your filter needs.
- Price
- Sometimes a regeneration is enough, and sometimes we remove or replace the filter, so there is no single price. We tell you the price after the check, before the work.
- Payment
- Cash or through a company.
- Place and time
- Tell us your city, we agree it by phone.
What the price depends on
- Whether forced regeneration or cleaning is enough, or a replacement is needed.
- How hard it is to remove the filter on your car.
- Whether the catalytic converter is cleaned along with the filter.
- Which fault fills the filter and what the repair needs.
When we remove the filter
- An inspection of the filter channels
- Measuring the filter before and after cleaning
- A checked regeneration after the filter is refitted
What others say, and what is true
- “Clean it, refit it and you are done.” After cleaning we check and set up the computer for a cleaned filter.
- “After cleaning the filter is like new.” No one can say how long a cleaned filter lasts. It depends on the cause and on the driving.
How we clean the DPF
- 1
You describe what is happening
Send us the make, model, year and mileage of the car and describe what is happening: the light, the power, how often regeneration runs. From another city you can also send a removed filter by courier. We agree the place, time or shipping by phone.

We find what fills the filter
With a device we read the faults and how full the filter is. We check the engine parts that fill the filter. When needed, we remove the filter and look at the channels.
- 3
We tell you what is needed and the price
Before the work we tell you what needs cleaning or replacing, which fault fills the filter and the total price. We also fix the fault that makes the filter fill up.
Work starts only when you agree.
- 4
We clean the filter
As agreed, we run a forced regeneration, clean the removed filter or fit a new one. We measure a removed filter before and after cleaning and show you the result.
- 5
We check how it works after cleaning
If we removed the filter, we refit it and set up the computer for a cleaned filter. We check the faults and whether regeneration completes.
Soot and ash: why driving does not clean everything
A DPF is a ceramic honeycomb. The channels are closed alternately, so the gas has to pass through the channel wall, and the soot stays on the wall.
Soot burns while driving and during regeneration. The oil the engine burns also leaves ash. Ash does not burn and collects at the end of the channels the whole time the filter works.
How to make the filter last longer after cleaning
Drive longer now and then, use the oil the car manufacturer specifies and do not drive for long with the filter light on. More about DPF regeneration

Questions
The DPF light stays on even after a longer drive?
That is a sign the filter is full. First we check how full the filter is and what fills it, then we say whether a regeneration, cleaning or replacement is enough.
Regeneration happens more and more often?
The filter fills faster than before. First we check how full the filter is and what fills it.
How much does DPF cleaning cost?
It depends on what the filter needs and whether the fault that fills it needs repairing. We tell you the total price after the check, before the work.
Is it better to clean or replace the filter?
After the inspection we tell you whether the filter can be cleaned or needs replacing. A new filter is needed when it is cracked or melted, or when it holds more ash than cleaning can remove.
Why does the filter clog again after cleaning?
The filter can clog again because of short trips or a fault in the EGR valve, the injection or the filter sensors. We look for the fault before cleaning and fix it, and give you advice on driving.
Can a DPF be cleaned without removing it?
Without removal, a cleaning agent is injected into the filter, followed by a regeneration. That removes soot, but not ash. So we remove a filter full of ash.
The filter clogged before 100,000 km. Why?
The cause can be another fault, for example an engine that burns oil.
The oil level is rising. What does it mean?
There may be diesel in the oil. Then the oil needs changing before cleaning.
