Peugeot 208 Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) on Peugeot 208 models captures fine soot particles from exhaust gases via a network of internal channels. It can remove up to 99 % of harmful emissions to comply with Euro 5 and Euro 6 standards. The DPF is made of stainless steel and contains a ceramic monolith coated to optimise filtering efficiency and durability.

The DPF is fitted on Peugeot 208 phases 1 and 2 mainly with these engines:

• 1.4 HDI
• 1.5 BlueHDI 100/102 CV (Euro 6)
• 1.6 HDI 90/92 CV (code 9HP, Euro 5 standard, from 2012+)

Each engine variant may have specific part numbers and sensor configurations but share the common function of particulate filtration and regeneration.

Typical symptoms include :

• Illuminated engine or DPF warning light on the dashboard
• Loss of engine power and poor acceleration due to exhaust blockage
• Increased soot level above 50 grams causing partial or total blockage
• Specific diagnostic trouble codes like P242F or P2463 indicating ash accumulation or additive levels too low

Proper diagnosis requires OBD2 scanning and pressure sensor checks. Ignoring warnings can lead to severe engine issues.

The DPF consists of two main parts: an upper catalytic converter and a lower particulate filter. Differential pressure sensors before and after the DPF monitor soot accumulation.

• Automatic regeneration : The vehicle periodically burns off soot at high temperature during long, high-speed drives to clean the filter.
• Forced regeneration : Can be initiated via diagnostic tools (e.g., Diagbox) when automatic cleaning is insufficient.
• Additive refill : The cerine additive pouch needs replacing periodically to assist combustion of soot.
• Driving conditions : Regeneration requires driving at sustained engine speeds (2500-3000 rpm) for 20-30 minutes, without disconnecting sensors.

This system ensures minimal emissions and healthy engine performance when properly maintained.

Several maintenance approaches include:

• Chemical cleaning : Using approved additives injected and circulated to help dissolve soot. Followed by a controlled drive cycle for regeneration.
• Non-dismount cleaning : Possible on some models like the 1.4 HDI for a low-cost solution using additives combined with diagnostics.
• Dismount cleaning : Removing the lower DPF section for manual cleaning or replacement; should be done by professionals.
• Replacement : Installing a new high-quality DPF compliant with standards for best reliability.

Regular checks and keeping additive levels in range are crucial to avoid costly repairs or performance loss.

To maintain optimal DPF function :

• Avoid frequent short journeys that prevent DPF regeneration
• Prefer regular motorway driving to keep regeneration cycles effective
• Use diagnostic tools like Diagbox or OBD2 scanners to monitor DPF additive and soot levels
• Do not ignore warning lights or error codes; address issues promptly
• Respect environmental regulations; never remove or bypass the DPF system

These practices enhance fuel performance, lower emissions, and prolong the service life of the DPF and engine.

Krosfou offers new Diesel Particulate Filters of exceptional quality, made in Europe with stainless steel INOX 409 and advanced ceramic monolith technology certified by TÜV SÜD Automotive.

• 3-year warranty covering use up to 100,000 km
• Superior or equal technical characteristics compared to original equipment
• Manufactured and tested according to strict European regulations
• Direct-from-factory supply ensuring competitive pricing without refurbished parts

Choosing certified DPFs from Krosfou ensures durability, environmental compliance, and peace of mind for Peugeot 208 diesel vehicle owners.

Resetting the DPF warning without addressing the root cause is not recommended. Proper servicing includes :

• Performing forced regeneration via diagnostic tools after cleaning or additive replacement
• Checking and refilling the additive pouch (cerine) following the manufacturer’s procedures
• Using a Diagbox or OBD2 scanner to clear codes only after successful regeneration

Driving conditions must meet regeneration criteria to avoid immediate reactivation of warning lights. Consult an authorised workshop for precise diagnostics and servicing.

Remember, ignoring the warning or frequently clearing codes without servicing can degrade fuel performance and ultimately damage the engine.
