How does a DPF clean itself?
How does a DPF clean itself?
The soot particles attach themselves to the lining of the DPF while the engine is running. At the same time, the filter is slowly clogging with the very particulates that it’s designed to remove from the exhaust. This process of cleaning the DPF is done through a process called regeneration.
How do you know if you need to clean your DPF?
Check the dash panel for a small, yellow or orange rectangular warning symbol with circles in the center. This symbol shows that the DPF soot has built up to a possibly damaging level. Always clean the DPF immediately when you see the warning symbol.
What to do when your DPF filter is blocked?
Forced regeneration: Mechanics can carry out a forced regeneration where they burn the soot off for you. This is expensive, and can only be done 4 times before it damages the filter permanently. This is usually done once the filter becomes very blocked and the car goes into limp mode.
What causes a blocked DPF on a car?
Your DPF will become blocked when soot builds up in it. To clear it, the soot needs to burn away, which is called “regeneration”. There are several ways that DPF regeneration can happen: Passive regeneration: This happens naturally when the car gets hot enough, during long drives at a high speed.
Why is my diesel particulate filter clogged up?
Similar to EGR problems, the DPF can become clogged up from city driving where the car does not get up to temperature. The whole reason the Diesel Particulate Filter came along was to clean up the diesel car image (Euro 5 Emissions, 2009).

Why do I keep getting DPF problems in my car?
Its your driving habits as the car owner and lack of knowledge with modern diesel cars. If you are driving a few miles each day, your DPF will eventually give up and repair bills will start piling up. A gasoline engine is perfect for short journeys and equally as efficient on fuel.
