Peugeot 4007 Diesel Particulate Filter DPF (2007-2012)

The Diesel Particulate Filter (DPF) on the Peugeot 4007, especially on models with the 2.2 HDi diesel engine, is a critical exhaust component designed to trap fine particulate matter from the engine's emissions. It helps reduce the amount of harmful soot released into the atmosphere, thereby lowering the vehicle's environmental impact.

The DPF discussed here is designed for Peugeot 4007 vehicles equipped with the 2.2 HDi engine producing approximately 156 hp (115 kW), manufactured from July 2007 onwards. There are also related references available for the 2.0 HDi 147 hp variant.

Signs that your DPF may be clogged include poor car performance, elevated exhaust backpressure, and the illumination of the DPF warning light on the dashboard. Additionally, you might experience a "check DPF system" warning code.

• Reduced engine power or acceleration
• Increased fuel consumption
• Frequent activation of the DPF warning light
• Unusual exhaust smells or smoke

If these symptoms occur, it's important to take your vehicle to an expert service for a proper scan and diagnosis rather than attempting a DIY fix.

Yes, clearing the warning light typically requires a DPF regeneration process or a scan tool to reset the vehicle's diagnostic system. This can be:

• Passive regeneration during normal driving at higher speeds
• Active forced regeneration triggered by a diagnostic tool or ECU command
• Manual reset with specialized scan tools by an expert technician

Improper or frequent resets without addressing the underlying cause may lead to recurring problems or damage.

Replacement can be done by experienced DIYers using detailed manuals and video tutorials. The estimated labour time is about 1 hour for the 2.0 HDi 147 hp model, but can vary for others like the 2.2 HDi. It's crucial to follow safety precautions and have the correct tools for handling exhaust components.

However, consulting a professional expert is recommended for diagnosis, removal, and installation especially to ensure correct sensor reconnections and system resets.

The most frequently reported issue with the Peugeot 4007 DPF is clogging due to accumulation of soot and particulate matter. This is considered a classic problem and results in:

• Activation of the DPF warning light
• Decreased vehicle performance
• Frequent need for forced or active regeneration
• Potential requirement for filter replacement if cleaning fails

Forums and user discussions indicate these are common symptoms and highlight the importance of timely service and maintenance.

High-quality and certified DPFs for Peugeot 4007 2.2 HDi engines are available through specialist suppliers who offer brand-new parts compliant with European regulations and manufacturer specifications. These products come with warranties typically covering 3 years or 100,000 km.

• New DPF with combined catalytic converters
• Manufactured in durable stainless steel
• Produced with high-performance monoliths and coatings
• Certified by leading automotive authorities for quality and reliability

Always confirm part reference compatibility and consult vehicle service experts before purchasing.

Proper maintenance includes ensuring regular vehicle use at sufficient speeds to allow passive regeneration, monitoring exhaust system health, and avoiding unnecessary short trips that cause soot buildup.

• Use recommended fuel and engine oils to reduce contaminant emissions
• Schedule regular vehicle checks and DPF system scans with an expert
• Perform forced regeneration if suggested by diagnostic codes or warning lights
• Seek professional cleaning services if soot accumulation is significant

By following these guidelines, you can enhance your car’s exhaust performance, reduce emissions, and avoid costly repairs.
