Description

This listing covers the diesel particulate filter (DPF) for the Peugeot 308 1.6 HDi, specifically for engine codes 9HX and 9HZ, manufactured between 2007 and 2014. This Euro 5 compliant DPF is a critical component for controlling exhaust emissions and ensuring your vehicle passes its MOT.

The DPF is designed to trap soot and particulate matter from the exhaust gases. Over time, these filters can become blocked or damaged, leading to reduced engine performance, increased fuel consumption, and dashboard warning lights. Common failure modes include excessive soot loading due to short journeys, failed regeneration cycles, or issues with associated sensors (e.g., differential pressure sensor, EGT sensor). Additive system faults (Eolys fluid) can also contribute to premature DPF blockage. Physical damage, such as cracks or melting of the ceramic substrate, can occur from extreme heat or impact.

At Gap Turbos, we specialise in DPF cleaning services. For this Peugeot 308 1.6 HDi unit, we offer a comprehensive workshop ultrasonic and thermal cleaning process. This method effectively removes accumulated soot and ash from the DPF substrate, restoring flow characteristics close to new condition. This cleaning service is typically 70-90% cheaper than full DPF replacement, offering a cost-effective solution when the ceramic substrate remains intact. We also offer mobile cleaning services and forced regeneration where appropriate. It is important to note that DPF removal is illegal in the UK and will result in an MOT failure.

Specifications

Vehicle fitment

• Peugeot 308 1.6 HDi

Common faults & troubleshooting

• Reduced engine power or ‘limp mode’: Often indicates a severely blocked DPF restricting exhaust flow; requires DPF inspection and potential cleaning.
• DPF warning light on dashboard: Suggests the DPF is reaching its soot load limit or a regeneration cycle has failed; attempt a forced regeneration or seek professional cleaning.
• Increased fuel consumption: A blocked DPF can cause the engine to work harder, leading to higher fuel usage; check DPF back pressure.
• Strong diesel smell from exhaust: Can indicate a failed DPF regeneration or a cracked DPF substrate, allowing unburnt fuel or gases to escape.
• Excessive white smoke from exhaust: May point to issues with the DPF additive system (Eolys) or failed regeneration attempts leading to unburnt fuel.
• Engine cutting out or difficult to start: In extreme cases of DPF blockage, exhaust back pressure can become so high it prevents the engine from running correctly; immediate DPF service is required.

Fitting notes for this unit

• Replace all gaskets and clamps: Always use new exhaust gaskets and clamps when refitting the DPF to ensure a leak-free seal and proper sensor readings.
• Check differential pressure sensor and pipes: Inspect the differential pressure sensor and its connecting pipes for blockages or damage, as these are critical for DPF monitoring and regeneration.
• Refill Eolys additive: Ensure the Eolys fluid reservoir is topped up after DPF service, as low levels will inhibit regeneration and can lead to rapid re-blocking. Reset the additive counter using diagnostic tools.
• Clear fault codes and perform adaptation reset: After DPF cleaning or replacement, use a diagnostic tool to clear all related fault codes and perform a DPF adaptation reset to inform the ECU of the new DPF status.
• Monitor post-installation regeneration: After clearing codes and resets, perform a road test to encourage a regeneration cycle and monitor DPF parameters to confirm correct operation.
• Torque exhaust bolts correctly: Ensure all exhaust manifold and DPF mounting bolts are torqued to the manufacturer’s specifications to prevent exhaust leaks or damage to the DPF housing.
