Peugeot RCZ Diesel Particulate Filter DPF (2010-2015)

The Diesel Particulate Filter (DPF) in the Peugeot RCZ is designed to prevent fine particulate matter emitted from the diesel engine exhaust from being released into the atmosphere. It traps particles as small as 0.1 microns by forcing exhaust gases through its filter walls, helping to reduce air pollution and comply with emission standards such as Euro 5.

The regeneration system periodically burns off accumulated soot inside the DPF to maintain filter efficiency. This process is managed automatically by the engine control unit (ECU), which increases the exhaust gas temperature to combust the trapped particles. It uses sensors to monitor pressure differences across the filter to detect clogging and triggers regeneration when necessary.

The engine control unit employs several technical methods to raise the temperature:

• Post-injection and catalytic converter post-combustion: injecting additional fuel late in the combustion cycle.
• Turbocharger management: maintaining engine torque while optimizing exhaust flow.
• Redirecting intake air flow to enhance combustion in the regeneration cycle.

These integrated techniques ensure complete burning of soot residues without damaging engine performance.

While soot particles are burned during regeneration, the additive used in the filter does not burn off. Over time, this additive accumulates and causes gradual clogging. The engine management system monitors the additive quantity and adjusts accordingly to manage normal clogging progression, but eventual cleaning or replacement may be necessary.

Several solutions exist for maintaining or cleaning a clogged DPF:

• Professional cleaning services offer DPF cleaning without replacement, often with operational guarantees.
• Additive products such as specialized DPF cleaners can help ease soot removal.
• Mechanical cleaning methods by specialized garages to unblock or restore filter performance.

Regular maintenance and correct driving habits can extend DPF life and reduce costs.

Yes. Many Peugeot RCZ diesel owners encounter issues related to DPF clogging, especially when the vehicle is frequently used for short runs that do not allow the engine to reach optimal operating temperature. This can prevent effective regeneration, triggering warning lights and faults. Some owners consider illegal DPF removal, which is strongly discouraged due to legal and environmental implications.

• DPF clogging caused by insufficient driving time at higher temperatures.
• Warning lights related to particle filter faults.
• Possible need for forced regeneration or professional cleaning.

Proper driving practices and timely maintenance checks are recommended to avoid these issues.

The Peugeot RCZ Coupé 2.0 HDi 163 HP (engine code DW10CTED4) is equipped with a DPF compliant with Euro 5 emission standards. The filter is designed with high-quality materials and advanced ceramic monolith technology that ensures durability and efficiency. It operates together with the catalytic converter system to reduce exhaust pollution effectively.
