Peugeot 1007 Diesel Particulate Filter DPF (2004-2009)

The DPF on a Peugeot 1007, especially the 1.6 HDi FAP 110 hp model with the 9HZ DV6TED4 engine from 2007 onwards, is an essential diesel emission control device. Located in the exhaust system after the catalytic converter, it traps up to 99% of fine particulate matter such as soot and ashes produced during combustion, thus reducing harmful emissions.

The DPF consists of a ceramic body with around 50 microscopic channels per cm² that form a porous network. Exhaust gases flow through these channels while solid particles like soot are trapped on the walls. Its operation includes three main stages :

• Filtration: soot accumulates forming a layer inside the filter channels.
• Passive regeneration: at high engine loads, exhaust heat above 600°C burns off the soot naturally.
• Active regeneration: initiated by the engine ECU when pressure sensors detect blockage, involving adjustments like post-injection and turbo control to raise temperatures to 500-600°C to burn soot into CO2, water, and non-combustible ash.

Additionally, an additive helps lower soot combustion temperature, aiding regeneration especially under low-load conditions.

The DPF is primarily fitted on the Peugeot 1007 1.6 HDi FAP with the 9HZ DV6TED4 engine from 2007 onwards. This filter is integrated into the exhaust line after the catalytic converter and is designed specifically for these diesel models to capture harmful combustion particles.

Common issues arise from soot and ash build-up inside the DPF, leading to higher exhaust back pressure and reduced engine power. This is often caused by :

• Short trips insufficient to trigger regeneration
• Consistently low engine load preventing soot combustion

Symptoms include loss of power, dashboard DPF warning light activation, and engine ECU detecting pressure sensor anomalies.

To maintain a healthy DPF and avoid clogging :

• Drive regularly at sustained highway speeds allowing passive regeneration (about 15-20 minutes at full throttle)
• Use manual regeneration via diagnostic tools if recommended
• Consider additives formulated to assist soot combustion in low load conditions

If cleaning by regeneration fails and ash accumulation is excessive, DPF replacement may be necessary.

The DPF on the Peugeot 1007 is installed in the exhaust system, specifically after the catalytic converter and before the silencers. This positioning optimises filtration and regeneration processes in the exhaust line. Replacement tutorials are available illustrating this location and procedure.

Key components related to the DPF include :

• DPF itself, designed to meet original equipment specifications
• Pressure differential sensor and associated piping that monitor filter status and trigger regeneration
• Additive system to lower soot combustion temperature during regeneration

Proper functioning of these parts ensures effective filtration and long DPF lifespan.

DPF health can be monitored by checking :

• Dashboard warning lights indicating DPF or engine issues
• Engine diagnostics using OBD tools to read pressure sensor data and error codes
• Engine performance, watching for power loss or increased fuel consumption

Regular highway driving encourages natural regeneration, helping maintain proper DPF function.

If issues persist, professional diagnostic and servicing are recommended to avoid engine derating modes.
