Specialized service · FAP/DPF
The Particulate Filter (DPF/FAP) is the exhaust component that captures soot and ash particles.
When it clogs, the engine enters safe mode. Professional cleaning avoids replacement — which can reach expensive values.
What is the DPF/FAP
The Particulate Filter works as a residue "trap" in the exhaust system of diesel cars. Since diesel engines emit a lot of soot, this filter is essential to prevent that pollution from reaching the atmosphere. It has an internal ceramic honeycomb structure that retains particles while gases pass through.
The filter cleans itself by burning accumulated soot (regeneration). On long journeys, this happens naturally. On short urban trips, the car forces the process — but if it fails repeatedly, the filter clogs and the warning light comes on.
Failure symptoms
Consequences
A clogged Particulate Filter is not just a dashboard light. It's a problem that worsens quickly and can result in much more expensive damage if ignored.
