Citroen C4 Spacetourer Diesel Particulate Filter DPF (2013-2021)

The Diesel Particulate Filter (DPF) is a porous silicon carbide component designed to trap pollutant particulates (soot) from the exhaust gases of diesel engines. It periodically burns off the captured soot through an automated regeneration process managed by the vehicle's engine control unit, effectively reducing emissions to near zero for BlueHDi engines.

Only the diesel BlueHDi engine versions have a DPF installed. Petrol engines like PureTech and THP are not fitted with a DPF. Here is a summary by engine version:

• 1.5 BlueHDi 130 hp – Yes
• 1.6 BlueHDi 100/99 hp – Yes
• 1.6 BlueHDi 115/116/120 hp – Yes
• 2.0 BlueHDi 150 hp – Yes
• 2.0 BlueHDi 160/163 hp – Yes
• PureTech and THP petrol engines – No

Typical replacement times range around 30 minutes to 1 hour depending on the engine model.

The DPF is located underneath the vehicle floor, situated after the catalytic converter. In some cases, it may be integrated within the catalytic converter assembly.

• The additive tank for Eolys cerine is positioned near the fuel tank, under the vehicle, which helps lower the combustion temperature needed for soot regeneration.

This design supports optimal filtration and regeneration efficiency.

The DPF typically lasts between 120,000 and 180,000 km, depending on driving style and maintenance, with shorter lifespan expected for predominantly short urban trips.

• Professional replacement is recommended, involving vehicle lifting, exhaust disconnection, and ECU reset using diagnostic tools.
• Cleaning or replacement should be considered when indicated by vehicle diagnostics or performance loss.

The average replacement cost generally ranges from €1,065 to €1,145 including parts and labour.

Proper maintenance and driving habits can prolong DPF life:

• Regular motorway drives at engine speeds above 3,000 rpm promote passive regeneration.
• Use of fuel additives designed for cleaning the DPF.
• Professional DPF cleaning services periodically.
• Avoid frequent short trips that prevent complete regeneration cycles.

These practices help maintain filter efficiency and reduce blockage risk.

The DPF uses silicon carbide (SiC) monoliths for their superior durability and high-temperature resistance compared to cordierite materials, providing highly effective filtration and longevity under demanding conditions.

This advanced material choice aligns with Euro emissions standards compliance.

When choosing a DPF product, consider the following:

• Ensure compatibility with your Citroën C4 Spacetourer engine model and power output.
• Select products that meet or exceed original equipment specifications and certifications.
• Check product references carefully to match your car’s engine code and Euro standard compliance.
• Prefer new, original products rather than reconditioned parts.

Proper product selection is essential for long-lasting performance and warranty validity.

Reliable sources for further information include:

• The official Citroën website offers technical explanations on DPF function, regeneration, and maintenance.
• Automotive parts specialist sites provide detailed product listings, installation guides, and additive recommendations.
• Forums and community groups for Citroën C4 Spacetourer owners share experiences and practical advice.
• Professional workshops equipped with diagnostic tools for DPF system checks and servicing.

Always ensure that any advice or products comply with your vehicle’s specifications and local regulations.
