Frequently asked questions
What does a Diesel Particulate Filter (DPF) do?
A DPF traps harmful soot particles from diesel exhaust and burns them off through a process called regeneration. This keeps emissions low and your engine running efficiently.
How do I know if my DPF is blocked?
Warning lights, loss of power, poor fuel economy, and limp mode are all signs of a blocked DPF. Ignoring them can lead to expensive repairs.
How long does a catalytic converter last?
Most catalytic converters last 10 years or around 160,000 km, but lifespan depends on driving style, fuel quality, and engine health.
What are the signs of a failing catalytic converter?
Common signs include loss of power, rattling noises, poor fuel economy, excessive exhaust smell, or a check engine light.
Can I remove my DPF or catalytic converter?
No — removing emissions systems is illegal in Australia, causes harmful pollution, and can void insurance or lead to fines. The safer option is cleaning or replacement.
