DPF Cleaning — what we do
DPF Diagnostics
We check the particulate filter clogging degree and its throughput. We determine the optimal cleaning method depending on the filter state.
Removal
We carefully remove the particulate filter without damaging the exhaust system. We prepare the filter for further cleaning.
Chemical Flushing
We perform cleaning using specialized washing compositions. This method allows removing soot and oil deposits without damaging the filter structure.
Acid Flushing
Deep cleaning for filters with heavy contamination and high ash content. Allows restoring throughput in complex cases.

Particulate Filter Flushing at Doc Serwis Auto Service
The particulate filter (DPF) is designed to trap solid particles in the exhaust gases of a diesel vehicle. During operation, it gradually accumulates soot and ash deposits, which reduces its throughput and disrupts engine operation.
What is particulate filter flushing
Particulate filter flushing is a deep cleaning procedure of the filter element from soot, ash and oil deposits. Cleaning is performed outside the vehicle using specialized chemical and acid compositions.
When DPF flushing is necessary
It is recommended to contact for particulate filter flushing if:
- ecology errors appeared
- engine lost power
- fuel consumption increased
- regeneration doesn't go through or starts frequently
- vehicle is operated mainly in the city
How particulate filter flushing is performed at Doc Serwis
The flushing procedure is selected individually and includes:
- filter state diagnostics
- particulate filter removal
- cleaning by chemical or acid method
- flushing and removal of contamination residues
- drying and throughput check
Why flushing is better than replacement
Particulate filter flushing allows significant savings compared to buying a new element. With proper cleaning, the filter preserves its design and lifespan. In most cases, flushing fully restores filter functionality and extends its service life.
