Peugeot 807 Diesel Particulate Filter DPF (2002-2014)

The Diesel Particulate Filter (DPF) on the Peugeot 807 is an integrated component in the exhaust system that traps and accumulates harmful particles produced by the diesel engine’s combustion process. This reduces pollutant emissions by capturing particles from the exhaust gases. Periodic regeneration phases burn off these particles to maintain filter efficiency.

The DPF is fitted on several diesel engine versions of the Peugeot 807, produced between 1998 and 2014:

• 2.0 HDi (RHH, engine code DW10CTED4), power 107-110 hp, Euro 5 standard, with combined DPF and catalytic converter (2010-2013)
• 2.0 HDi (E, engine code RHM), power 107 hp, manufactured 2003-2004, with new DPF available
• 2.2 HDi engines, with or without catalytic converter, produced 2003-2011 – DPF length approx. 540 mm, weight 5 kg

These filters are designed to comply with Euro 4 and Euro 5 emissions regulations by combining particulate filtering with catalytic conversion.

The most frequent problem is DPF clogging or blockage due to excessive particle accumulation if regeneration does not occur properly, often caused by short trips or using unsuitable engine oil. Symptoms include:

• Loss of engine power and performance
• Illuminated warning light on the dashboard
• Vehicle entering limp or degraded mode

Professional cleaning methods—chemical or mechanical—can restore filter function and extend the DPF service life.

Replacement can be done by experienced technicians or DIY enthusiasts using step-by-step illustrated guides and video tutorials that cover disassembly, required tools, and safety precautions.

• New DPF units for the 2.0 HDi and 2.2 HDi engines are available with original quality and long-term warranties.
• Filters are compatible with some related models like Citroën C8 and Fiat Ulysse due to shared platforms.

Consulting technical manuals (RTA) is recommended for correct installation, diagnosis, and ongoing maintenance.

Yes, high-quality new DPFs offered are sold with a 3-year warranty covering usage up to 100,000 kilometres. These filters meet or exceed original equipment standards and are manufactured with premium materials such as stainless steel and advanced ceramic monoliths.

Symptoms to check include:

• Warning lights or fault codes related to particulate filter or emission control
• Reduced engine performance or hesitation during driving
• Unusual fuel consumption patterns

Diagnostic log checks at an authorised garage or dealer can confirm if the DPF is blocked or failing and advise on maintenance or replacement.

DPF regeneration is a process that burns off accumulated soot to keep the filter clear. It can be automatic during normal driving but may fail if the vehicle is used mostly for short trips or city driving. In some cases, an additive fluid is used to enhance regeneration efficiency, but always use additives recommended by PSA specifications to avoid filter damage.

• Regular drives on open roads and highways favour effective automatic DPF regeneration.
• Service intervals and oil type affect DPF lifespan and performance.

Proper driving habits and maintenance extend the time between costly removals or replacements.

High-quality new DPF parts with original specifications are available from specialised suppliers that offer fast delivery and warranty. For technical advice and installation guidance, consult professional garages or official dealer networks. Useful online forums and tutorial sites can provide detailed vehicle-specific information.

• Always verify part compatibility via vehicle VIN or engine code when ordering.
• Keep maintenance logs and service history for accurate diagnostics.
• Follow official Peugeot technical bulletins for updates and software recalibrations related to DPF systems.

Choosing certified parts and professional service helps maintain your Peugeot 807’s emission control and engine health effectively.

Remember, a well-maintained DPF contributes significantly to reducing pollution on the road and protecting the environment.
