Citroen C4 Grand Picasso Diesel Particulate Filter DPF

The DPF on a Citroën C4 Grand Picasso diesel engine captures fine soot particles from the exhaust to reduce pollution. It is usually located in the exhaust system under the vehicle, after the catalytic converter. The captured soot is periodically burned off in a regeneration process aided by additives, ensuring compliance with EURO emission standards.

DPF is present mainly on diesel engine versions:

• 1.6 HDi (109, 110, 112 hp)
• 2.0 HDi (136, 138, 150, 163, 165 hp)
• Also on some gasoline engines like 1.2 i GPF (Gasoline Particulate Filter) compliant with EURO6 since mid-2018

Gasoline versions without diesel engines generally do not have a DPF.

DPFs are made from either silicon carbide or cordierite. Silicon carbide is preferred for its durability and high-temperature resistance, providing efficient filtration and strong mechanical integrity.

• Housed inside stainless steel (INOX 409) casings
• Coated with rare metal layers for enhanced performance

This construction ensures long-lasting, high-performance pollution control.

New DPF prices for diesel versions (like 1.6 HDi) start around €145 (tax included). Complete kits including DPF and catalytic converter can cost around €400 or more.

• Replacement labor and parts typically range from €1,074 to €1,400 at garages
• Duration of replacement work varies by engine model, from about 54 minutes to over an hour

Check with your service provider for exact quotes based on your specific vehicle model and engine.

The DPF should be changed or professionally cleaned between 120,000 and 180,000 km depending on driving conditions. Key practices include:

• Regular highway driving at engine speeds above 3,000 rpm to facilitate passive regeneration
• Use of appropriate fuel additives
• Avoiding frequent short trips that prevent full DPF regeneration
• Periodic diagnostic checks and professional cleaning when recommended

Maintaining the additive reservoir (cérine Eolys) level for regeneration support is also important.

The DPF is located under the vehicle, typically after the catalytic converter in the exhaust system. Replacement involves:

• Lifting the vehicle safely
• Disconnecting exhaust components
• Removing the old DPF
• Installing and securing the new DPF
• Resetting the vehicle's onboard diagnostic parameters

This task is recommended to be performed by a professional mechanic but some DIY guides are available for experienced users.

Krosfou offers a 3-year warranty on new DPFs with usage limited to 100,000 km. The warranty covers manufacturing defects if the DPF is installed by a professional and proper maintenance has been followed.

• Negligence or improper use (like frequent short trips preventing regeneration) voids the warranty
• Clogged DPFs are not covered under warranty
• Customers receive support and technical assistance from Krosfou when needed

Always keep installation and service invoices to validate warranty claims.

To ensure correct compatibility, provide your vehicle's VIN or engine reference when ordering. This helps confirm the DPF matches your specific model and complies with the relevant EURO standards.

• Krosfou offers direct factory support to confirm part fitment and sensor positioning
• Check product dimensions and technical specifications carefully before purchase
• Use diagnostic tools after installation to reset vehicle parameters
