Opel Insignia Diesel Particulate Filter DPF

A diesel particulate filter (DPF) captures harmful soot particles from the exhaust gas. It's a critical part of CDTI diesel engines, helping your car meet Euro 5/6 standards. Without a functional DPF, your vehicle risks failing inspection or showing a DPF issue warning.

Look out for these:

• Dashboard warning light
• Loss of engine power
• Increased fuel use
• "Continue driving to clean filter" messages

You might also smell unburnt fuel or feel uneven wheel drive during acceleration.

You have two choices:

• Passive regeneration during high-speed drive
• Workshop regeneration using a scanner or pressure sensor-based reset

For heavily clogged units, professional cleaning or replacement may be required to restore standard condition.

DPF regeneration clears built-up soot by heating it to ash. If the process is interrupted, mounting kit components can be damaged. Always follow the in-car message prompts.

Our price range starts around €300 and includes original equipment and value-packed kits. You'll find filter-only options or bundles with converter and mounting hardware—ideal for repair or full exchange.

Not recommended. Clogging increases EGR pressure, lowers performance, and can harm your emission system. We suggest checking the dpf cleaning process early and planning a repair before it worsens.

Reasons include:

• Short trips
• Sensor or pressure fault
• Regeneration failure
• Blocked pipe or accessorie malfunction

Proper diagnostics can pinpoint if it's a filter issue or something upstream.

Use an OBD tool (e.g. ThinkDiag) or ask a garage to assist. Ensure the fuel level is sufficient and leave the car idling for the required hour to complete the cleaning.
