Volvo S80 Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) on a Volvo S80 captures fine particulate matter from the exhaust gases during driving. It uses an automatic regeneration process to burn off these trapped particles, clearing the filter. This regeneration requires the engine to reach its normal operating temperature and typically lasts 10 to 20 minutes. During this process, fuel consumption may slightly increase, engine power can temporarily drop, and there might be a noticeable burnt smell.

DPF regeneration needs the engine to reach its normal operating temperature, which can be difficult to achieve in cold weather or during frequent short trips. The process usually takes 10 to 20 minutes and requires consistent driving at a reasonable speed.

When the DPF reaches about 80% soot saturation, the driver will see a yellow warning triangle on the dashboard accompanied by the message "Filtre à suie plein Voir manuel" (Soot filter full, see manual). The recommended action is to drive for approximately 20 minutes on a road or motorway after the engine reaches its normal temperature to allow regeneration to fully complete.

The DPF system is primarily fitted on the Volvo S80 models with 1.6D 108hp engines (code D4164T) produced between 2009 and 2012, complying with Euro 5 standards. Additionally, the 2.4D D5 engine on the Volvo S80 II is equipped with a DPF tested according to UNECE regulation 103 Rev.1.

Replacement DPFs and combined catalytic converters for the Volvo S80 come with a 3-year warranty and comply with all manufacturer and European standards. Original equipment references such as 31293167 or 36001868 correspond to quality new parts often made in stainless steel (INOX 409). It is recommended to replace pressure hoses simultaneously since they often get damaged with repeated regenerations.

• Original part references: 31293167, 36001868, 36050310
• New DPF + catalytic converter combined units available (approx. 6 kg, length 720 mm)
• Recycling program available with possible compensation for eligible old parts

DIY manuals and video tutorials for replacement are accessible online to assist with the process.

Common issues include DPF clogging when regeneration does not occur properly, especially due to frequent short trips or cold weather driving preventing the engine from reaching normal temperature. When clogged, you may notice:

• Reduced engine power
• Increased fuel consumption during regeneration
• Burnt smell from exhaust
• Warning lights on the dashboard

To prevent problems, avoid repeated short journeys and consider using a parking heater to quickly warm up the engine in winter conditions.

Many Volvo S80 drivers report DPF issues related to incomplete regenerations and the resulting blocked filters. Forums and online resources are valuable for sharing experiences and solutions. Official Volvo support and authorized dealers can provide precise diagnostics and repair services for persistent issues.

• DPF warnings often require professional diagnostics
• Replacement parts must be genuine or certified to ensure proper functionality
• Proper driving conditions contribute to longer DPF life and fewer issues

If in doubt, consult your Volvo dealer or a specialist for advice and to verify that the correct original Volvo parts are used.

If the yellow warning triangle and soot filter message appear, follow these steps :

• Drive your car for around 20 minutes at normal operating temperature, preferably on a motorway or open road where the engine can reach consistent RPM and temperature
• Avoid short stops or city driving during this period to allow the regeneration process to complete fully
• If the warning persists, get the DPF system checked by a professional to avoid engine damage

Regular maintenance and avoiding short journeys during cold periods help maintain the DPF functional and efficient for longer.

Always use genuine or certified replacement parts for repairs to ensure compliance with emissions standards.
