Citroen C5 Aircross Diesel Particulate Filter DPF (2018-Today)

The Diesel Particulate Filter (DPF) on the Citroën C5 Aircross is an essential emission control device designed to capture fine particles (soot) from diesel engine exhaust gases. It uses a porous material made of silicon carbide or cordierite to trap particulate matter and periodically regenerates to burn off the deposits, reducing air pollution and helping the vehicle meet Euro 6 emission standards.

All Citroën C5 Aircross versions are equipped with a DPF to comply with Euro 6 emission regulations. This includes:

• 1.2 PureTech 130 (Petrol, direct injection, cordierite DPF)
• 1.5 BlueHDi 130 (Diesel with additive for combustion at 450°C)
• 1.6 PureTech 180 (Petrol)
• 2.0 BlueHDi 180 (Diesel)
• 1.6 Hybrid 224 cv (Hybrid requiring AdBlue® for DPF operation)

Each engine variant features a DPF adapted to its emission control needs.

The DPF works by:

• Trapping particulate matter like carbon, hydrocarbons, and sulfates in its porous structure located after the catalytic converter on the exhaust line.
• Performing passive regeneration when driving at high temperatures (550-600°C) on highways, which burns soot naturally — this process is easier with petrol engines due to hotter gases. The diesel engines use an additive to lower combustion temperature to about 450°C.
• Performing active regeneration during frequent short trips (city driving) by injecting fuel to heat the system and burn deposits, though ash buildup may still occur over time.
• Maintaining near-zero emissions compliant with HDi/DPF technology; hybrids also rely on AdBlue® for optimal system function.

This combination ensures efficient particulate capture and reduction of emissions.

DPF maintenance on the Citroën C5 Aircross includes:

• Automatic regeneration controlled by the vehicle’s ECU; regular highway driving favors effective passive regeneration.
• Manual cleaning is possible with moderate difficulty; steps include removing the DPF (unlocking bolts, pressure sensor, and clamps), cleaning dust and soot carefully with proper safety gear, applying a cleaner into the filter cells, and reassembling securely.
• DPFs generally show visible but fouled cells after about 150,000 km, signaling cleaning or replacement needs.
• Replacement times vary by model, commonly between 1 hour and 1 hour 24 minutes, with new product options available.

Regular attention prolongs DPF efficiency and vehicle performance.

Common DPF issues include:

• Frequent fouling during city or short trips causing clogging as active regeneration may not fully clear soot.
• Symptoms such as a warning light on the dashboard and noticeable power loss.
• Solutions involve cleaning the DPF manually or forcing regeneration via OBD diagnostic tools.
• Replacement DPF parts specific to engines like the 1.5 BlueHDi 130 are available with compatible references and certifications.

Addressing issues promptly helps maintain emission compliance and engine performance.

To verify the correct DPF item and reference:

• Check your vehicle details such as engine type, power output, and Euro standard.
• Use the specific product reference numbers (e.g., DV5RC for 1.5 BlueHDi 130 engine) to match the DPF part.
• Consult with trusted technical sources or official Citroën documentation for precise part numbers and sensor placement.
• If purchasing online, confirm compatibility by entering your vehicle model and engine details before adding the item to the cart.

Correct product selection ensures proper fit, performance, and compliance with emission standards.

Regarding shipping and warranty:

• Standard European delivery times range from 1 to 6 working days; express delivery options are also available.
• DPF products typically come with a 3-year warranty limited to up to 100,000 km of use from date of receipt.
• Free returns are accepted within 30 days for unused products in original packaging, with conditions applied for returns outside Europe.
• Warranty coverage requires professional installation and adherence to maintenance guidelines; issues caused by improper use (e.g., clogging from short trips) are excluded.

Always check specific terms of sale and warranty details with the supplier before purchase for a smooth buying experience.

For complete information and support:

• Consult official Citroën resources and Service Box guides for DPF technology and proper use of additives like AdBlue®.
• Access practical tutorials and repair manuals such as Revue Technique Auto (RTA) for detailed maintenance instructions and dismantling guides adapted to the C5 Aircross.
• Use technical customer support services from your DPF product supplier for installation manuals, compatibility confirmation by VIN, and expert advice.
• For diagnostics and forced regeneration, professional garage services equipped with OBD tools are recommended.

Always rely on verified technical documents and expert assistance to ensure safe and efficient DPF maintenance and replacement.
