Infiniti Q70 Diesel Particulate Filter DPF (2013-2018)

The Diesel Particulate Filter (DPF) in the Infiniti Q70 2.2d Diesel is a crucial component integrated into the exhaust system that captures harmful soot particles produced by incomplete diesel combustion. This reduces polluting and carcinogenic emissions to comply with Euro 5/6 standards and ensures cleaner air quality.

The DPF consists of a ceramic honeycomb structure with alternating porous channels, forcing exhaust gases to pass through its walls and trap soot. It includes an insulating layer, a catalytic converter, and sensors to monitor temperature and pressure differentials. The system creates backpressure that requires regeneration to burn off accumulated soot.

DPF regeneration is the process of burning off collected soot to restore filter efficiency. There are two types:

• Passive Regeneration: Occurs naturally when exhaust gas temperatures are high enough, typically during prolonged high-speed driving.
• Active Regeneration: The ECU injects extra fuel to raise the temperature above 600°C to burn soot, triggered when sensor data indicate high pressure differential.

Conditions for active regeneration include functioning sensors, adequate fuel level, non-blocked EGR, and suitable exhaust gas temperature.

Common issues include:

• DPF clogging, especially due to frequent short or urban trips that prevent regeneration.
• Faulty pressure or temperature sensors.
• Blocked Exhaust Gas Recirculation (EGR) valves.
• Low fuel levels disabling active regeneration.

Symptoms often are increased backpressure, loss of engine power, and an illuminated DPF warning light. Non-burnable ash accumulates after 150,000–180,000 km, requiring DPF replacement.

Maintenance tips for your DPF include:

• Forcing regeneration with regular highway driving at uniform high speeds and engine loads.
• Professional cleaning services using water and compressed air rinsing systems, which are effective and environmentally friendly.
• Avoiding excessive short trips that prevent filter regeneration.

Regular checks and sensor replacements when needed help prolong DPF life.

Choosing authentic spare parts protects your engine performance, fuel economy, and the environment.

Signs of a clogged DPF include:

• Illuminated DPF warning light on the dashboard.
• Reduced engine power and sluggish acceleration.
• Increased fuel consumption and possible excessive smoke from the exhaust.
• Frequent active regeneration attempts or failure to complete regeneration.

If you notice these symptoms, it is advisable to have a diagnostic check performed with OBD tools to read specific DPF error codes such as P2002 or P242F.
