Volvo C70 Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) in the Volvo C70 is an anti-pollution device integrated into the exhaust system of diesel engines, particularly the 2.0D and 2.4D5 variants. It captures soot and fine particles to comply with Euro 4 emission standards, helping to reduce engine emissions and protect the environment.

The DPF operates in two phases:

• Phase 1 (Accumulation): Soot particles from engine exhaust are trapped inside the filter, forming a layer of soot.
• Phase 2 (Regeneration): The trapped soot is burned off automatically at high temperatures through controlled fuel injection or additives. On the Volvo C70 II Cabriolet 2.0D, manual regeneration can be triggered by driving steadily at 60-80 km/h for 25-30 minutes to force the cleaning process.

A warning light will illuminate if the DPF becomes obstructed or fails, indicating the need for diagnosis and possibly cleaning or replacement.

DPFs are mainly found on these Volvo C70 versions:

• C70 III: Exact period unspecified; DPF replacement cost varies; soot accumulation may block the filter early in its cycle.
• C70 II Cabriolet 2.4 Mk2 D5 (2006-2011): Euro 4 compliant with D5244T13/D5244T8 engines; uses DPF without catalytic converter.
• C70 II Cabriolet 2.0D: Also fitted with a DPF; frequent DPF warning light; cleaning via steady-speed driving.

Always check your vehicle's engine model and regulations to ensure correct DPF maintenance and replacement parts.

• Regularly performing regeneration by driving consistently at 60-80 km/h for 25-30 minutes to burn off soot deposits.
• Engine decarbonisation before considering a filter replacement to avoid repeated clogging.
• Using only parts compliant with emissions regulations to ensure system longevity.

Ignoring the DPF warning can lead to engine power loss and potential costly repairs.
