Peugeot 2008 Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) on the Peugeot 2008, especially on diesel models like the 1.6 BlueHDi, is a crucial component of the exhaust system. It traps fine particulate matter (soot) from the exhaust gases with an efficiency of 99.9%, using a porous ceramic structure made from silicon carbide or cordierite that filters particles as small as 0.1 micron. The trapped soot is periodically burned off by a regeneration process at around 550°C, helped by a specific additive called cerine (Eolys) injected into the fuel tank, controlled by the vehicle’s computer system.

The DPF's structure forces exhaust gases to pass through porous channels which trap particulate matter while allowing gases to flow. Regeneration can be passive, occurring naturally during hot driving conditions above 550°C, or active, initiated by post-injection of fuel and turbo management to increase temperature (up to 4000 rpm engine speed). A differential pressure sensor monitors soot accumulation with different alert zones indicating clogging severity. If overloaded, a forced regeneration program runs the engine at both idle and high revs to burn off the soot.

Signs that your DPF may be faulty or clogged include:

• Increased fuel consumption
• Loss of engine power or acceleration
• Illumination of the Check Engine light or a specific DPF warning indicator

Ignoring these symptoms risks rapid blockage, especially with frequent short or city driving that prevents proper regeneration.

Compatible DPFs for Peugeot 2008 diesel models such as 1.6 BlueHDi comply with Euro 6 standards and are made from high-quality ceramic materials like silicon carbide or cordierite. They come with specific OEM or equivalent references and vary in length and weight depending on the exact engine model and year. Replacement filters are new, fully compliant with manufacturer and technical inspection requirements, and usually come with a detailed installation guide and certification.

• Models: 1.6 BlueHDi (BHW/DV6FE), 1.6 BlueHDi 100 (CU, BHY/DV6FD)
• Years: From 2015 to present, various Euro standard compliance (Euro 4, 5, 6)
• Materials: Silicon carbide or cordierite ceramic substrates

Always ensure the DPF meets the exact specifications for your vehicle to guarantee performance and emissions compliance.

Some maintenance tasks like cleaning or resetting the DPF may be attempted by knowledgeable owners, but the process often requires special equipment and additives (cerine-based fluid) injected into the fuel tank to assist regeneration. Incorrect handling or use of unsuitable fluids can damage the filter or engine systems.

• DPF additive fluid (Eolys) is specifically formulated to reduce soot combustion temperature
• Proper regeneration conditions (engine temperature and driving style) must be met to prevent blockage
• Cleaning or replacing the filter should ideally be done by professionals equipped with diagnostic tools

For safety and efficiency, professional service from a Peugeot garage or authorized workshop is recommended over DIY fixes.

Driving without a DPF or with a severely clogged filter is not advised and may be illegal due to emissions regulations. It can cause:

• Increased engine back pressure leading to power loss and damage
• Excessive emission of harmful particles and pollutants
• Failure to meet legal requirements impacting MOT or inspection tests

The DPF is an essential part of the exhaust system that helps reduce pollution and maintain engine health. If you experience persistent DPF issues, consult a Peugeot garage promptly for diagnosis and repair.

The lifespan of a DPF usually exceeds 100,000 miles (approx. 160,000 km) when properly maintained. Factors influencing lifespan include driving habits, fuel quality, and regular usage of regeneration cycles.

• Drive regularly at adequate speeds and distances to allow passive regeneration
• Use recommended diesel fuel and service with correct DPF additive fluids
• Address warning lights or power loss promptly with professional diagnostics

Preventing blockage through regular maintenance reduces risk to engine and avoids expensive replacements.

While some minor DPF maintenance might be manageable, the complexity and risk of damage often make professional garage intervention the best choice. Peugeot garages have the specific diagnostic tools and genuine parts suited to your vehicle’s model and engine.

• Access to manufacturer-approved DPF replacements and additive fluids
• Capability to perform forced regeneration to clear blockage safely
• Warranty and professional support that DIY solutions cannot provide

For lasting reliability and to meet emission requirements, trusting an authorized Peugeot garage ensures your Peugeot 2008’s DPF system is correctly maintained and repaired.

Remember that ignoring DPF issues or faulty repairs can lead to serious engine risks and fines due to non-compliance with environmental standards.
