Peugeot Expert Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) on Peugeot Expert is an essential component of diesel engines designed to reduce harmful particle emissions such as soot, hydrocarbons, and sulfates from exhaust gases. Installed after the catalytic converter on the exhaust line, it traps these particles at low temperatures (idle or city driving) and burns them off at high temperatures (550-600°C) during passive regeneration on highways.

DPF regeneration is the process of burning off trapped soot particles to prevent clogging. There are three main types:

• Passive Regeneration : Automatically occurs during high exhaust temperature driving, typically on the motorway.
• Active Regeneration : The engine management injects additional fuel into the exhaust to raise temperature via the catalytic converter when passive regeneration is insufficient.
• PSA Additive-Based Regeneration : Specific to Peugeot/Citroën diesels where an additive lowers the burn temperature to around 450°C.

Residual ash from burnt particles accumulates over time and requires periodic draining or filter replacement.

Common symptoms of DPF saturation or clogging include:

• Dashboard "Service" warning light illumination
• Messages alerting "risk of DPF clogging"

This mainly affects diesel HDi engines such as the 2.0 HDi DW10CTED4 Euro 5 and 1.6 HDi 90 8v DV6UC 9HM Euro 5.

Replacing the DPF is a straightforward operation typically taking around 43 minutes. The cost for parts starts at approximately €693 including VAT, with total costs including labour ranging between €750 and €975 including VAT.

Detailed guides are available for replacement procedures and for identifying saturation indicated by warning lights.

Compatible DPF parts vary by model and engine type. Examples include:

• Expert 2.0 HDi (DW10CTED4, RHH), 2010-2013, Euro 5 including combined catalytic converter and DPF
• Expert II 1.6 HDi 90 8v (VF3, 9HM DV6UC), 2011-2016, Euro 5 with certified E-mark and installation kits

Always verify Euronorm and engine compatibility via your VIN for precise fitment. For professional diagnostics, consult a Peugeot garage.

Several professional resources are available:

• RTA (Revue Technique Automobile) publications for comprehensive repair and maintenance (printed or digital)
• MTA (Méthode Technique Automobile) online guides for professionals covering filters, belts, and all repairs
• Step-by-step tutorials such as "How to change my Peugeot Expert DPF"
• Technical presentations on FAP/DPF technology outlining diesel pollution filtering

These empower users and developers to understand, test, and maintain DPF functionality correctly.

To ensure effective DPF regeneration and soot ash elimination, it is recommended to drive at 60-80 km/h for about 25-30 minutes regularly. This helps raise exhaust temperature for passive regeneration.

• Avoid frequent short city trips that prevent thorough regeneration
• Do not pressure wash the DPF without proper caution; if cleaning, ensure this is done according to the DPF structure and flow direction to avoid damage
• Use only manufacturer-approved processes and additives if applicable

Proper use and adherence to driving prescriptions help preserve your Peugeot Expert's DPF and overall engine health.
