Does DPF affect performance?
The DPF affects diesel engine performance in two ways. [1] Engine efficiency decreases with increasing backpressure due to thermodynamic reasons. The pressure drop of the DPF increases as it captures particulate matter from the engine. Large backpressure not only reduces efficiency, but could also damage the engine.
What can go wrong with a DPF?
It’s a failure to correctly regenerate that is the cause of most diesel particulate filter issues: they become blocked, which increases exhaust emissions, stifles engine performance and sometimes even puts the car into a restricted ‘limp-home mode’.
What does DPF do to a diesel particulate filter?
The Diesel Particulate Filter traps the harmful diesel gases that gets cleaned regularly by a process called DPF regeneration. The collected diesel soot particles are burnt off at high temperatures, which results in an “ ash-like ” after product.
What does Def stand for in diesel exhaust fluid?

What happens to your engine during DPF regeneration?
During an active DPF regeneration, you may notice the following: Higher idle RPM/Speed Cooling fan working harder Poor fuel economy Smells from exhaust Engine note change
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.
