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

The Diesel Particulate Filter (DPF) in Citroën C4 Spacetourer Diesel models such as the 1.5 BlueHDi 130 or 1.6 HDi Blue is a key component designed to capture and reduce fine soot particles emitted by diesel engines. It often works alongside SCR/AdBlue systems and additives like Eolys or Cerine to minimize exhaust emissions and comply with environmental standards.

Common issues include clogging due to soot accumulation, typically occurring after 20,000-30,000 km, resulting in power loss. Other reported faults involve DPF or AdBlue system failures, EGR valve, catalytic converter, turbo, and injectors. Official recall campaigns have targeted antipollution system faults and brake system issues. Warning lights may stay on indicating system failure, oil pressure problems, or immobilizer issues post-driving limits.

DPF maintenance involves regular regeneration to burn off soot buildup. Manual regeneration can be done by driving at 65-75 km/h for 24-30 minutes, ideally on highways. Additives such as Cerine/Eolys should be replenished if alerted by the onboard computer. Monitoring via the vehicle's display and periodic diagnostic checks at the garage help detect anomalies early, including oil pressure or brake system warnings.

Cleaning can sometimes be done without removing the DPF by using ECU-controlled methods. Replacement DPFs are available for various engine models, such as:

• 1.5 BlueHDi 130 (3-door): DPF with catalytic converter for oxidation
• 1.5TD HDi 131 cv (DV5RC YHZ): new DPF filter
• 1.6TD HDI Blue (DV6FC): compatible catalytic converters

Software modifications to disable AdBlue or DPF functions exist but are illegal and not recommended for public road use.

Signs include a constant antipollution warning light, loss of engine power, combined messages about DPF saturation, and system malfunction alerts such as fixed fault lights or oil pressure warnings. After certain limits, the immobilizer may block engine restart. Early diagnosis and intervention are advised to avoid costly repairs.

To avoid clogging, it is recommended to:

• Avoid frequent short trips that prevent the engine from reaching optimal temperature for passive regeneration.
• Regularly perform manual regeneration by driving at steady highway speeds for about 30 minutes.
• Keep FAP additives topped up as alerted by the dashboard system.
• Consult your garage for regular diagnostics to check for ECU error codes and other system statuses.

Following manufacturer maintenance instructions is crucial to prolonging DPF life.

High-quality, brand-new DPFs manufactured in Europe complying with strict standards are available. These DPFs are made with stainless steel and advanced ceramic monoliths for superior performance and durability. When purchasing replacement parts, always verify compatibility with your vehicle's model, engine type, and VIN to ensure correct fitment and optimal function.

Yes, original DPF products generally come with a 3-year warranty limited to 100,000 km of use. Free returns are typically offered within 30 days for unused, original packaging conditions. Warranty coverage requires proper installation by specialized garages and adherence to maintenance instructions. Negligence, improper use, or clogging from short trips may void the warranty.

Always consult your parts supplier for detailed terms regarding warranty and returns to ensure protection and proper service.
