Peugeot 1007 Diesel Particulate Filter DPF (2004-2009)

The DPF on the Peugeot 1007 diesel (including 1.4 HDi 68 CV 8HX and 1.6 HDi models) is an exhaust system component designed to trap fine particulate matter in diesel exhaust gases. It uses a porous silicon carbide structure that filters particles as small as 0.1 micron, reducing emissions by up to 1000 times compared to conventional engines.

The DPF system includes several key components:

• Main filter placed downstream of catalytic converters
• Pressure sensors upstream and downstream for differential pressure measurement
• Temperature sensors to monitor exhaust gas temperature
• Special additives (e.g., Eolys) stored in a dedicated tank and injected for soot combustion
• Engine control unit managing injection, regeneration, and additive levels
• Air intake warmer and turbocharger controls to help achieve regeneration temperatures

These parts collaborate to ensure effective soot trapping and burning during regeneration phases.

DPF regeneration removes trapped soot to prevent clogging. It happens in two ways:

• Passive regeneration: occurs naturally during long or high-speed drives when exhaust gases exceed 600°C, burning off soot periodically every 350-800 km.
• Active regeneration: triggered by the vehicle’s computer when soot load is high, involving a post-injection of fuel to raise exhaust temperature and burn soot actively. EGR recycling is temporarily disabled and turbo controlled to maintain optimal conditions.

Driving at 2500-3000 rpm for about 20-30 minutes on warm engine helps force regeneration and prolongs DPF life.

Common problems include:

• Clogging, especially with frequent short trips where the filter does not reach necessary temperature
• Loss of engine power and exhaust smoke upon clogging
• Engine rev limitation around 2200 rpm when DPF is blocked

Maintenance tips:

• Regularly drive 30–40 km at 2500-3000 rpm to enable regeneration
• Use diagnostic tools (e.g., PSA PP2000/Diagbox) to trigger forced regeneration if needed
• Use special fuel additives such as Diesel DPF Cleaner to aid soot combustion
• At high mileage (e.g., 160,000 km for 1.6 HDi), consider professional inspection and potential cleaning or replacement

The typical lifespan of the Peugeot 1007 DPF ranges from 80,000 to 140,000 km depending on driving habits and maintenance. Replacement is recommended if severe clogging occurs and cleaning is insufficient, commonly around or after 160,000 km. Replacement must be done at a specialized garage ensuring proper installation and vehicle compatibility.

Signs of DPF issues include:

• Warning lights on dashboard signaling DPF faults
• Engine power loss and restricted acceleration
• Unusual smoke or smell from exhaust
• Reduced engine speed limited to around 2200 rpm

If such symptoms occur, it is advised to use a specialized OBD diagnostic tool or visit a garage for an accurate check and possible forced regeneration.

Good practices to maintain DPF health include:

• Avoid frequent short trips that prevent reaching full operating temperature
• Drive for 20-30 minutes at 2500-3000 rpm when the engine is warm to facilitate soot burning
• Follow recommended service intervals for oil and filters
• Use diesel additives designed for DPF maintenance

These help ensure the DPF regenerates properly and maintains optimal filtering performance.
