Dodge Journey Diesel Particulate Filter DPF (2008-2020)

The Diesel Particulate Filter (DPF) on the Dodge Journey, mainly for diesel models like the 2.0 CRD (from 06/2008), is an essential anti-pollution device. It captures fine soot particles from diesel exhaust gases in a porous ceramic body and burns them off during a regeneration process to reduce emissions.

The DPF traps harmful soot in a honeycomb network with porous walls. When full, it initiates an automatic regeneration by raising exhaust temperature to incinerate trapped particles. This typically happens every few hundred kilometres and lasts several minutes. Regeneration should not be interrupted to avoid clogging.

Typical signs of DPF issues include:

• DPF or engine warning light illuminating (error codes P2002 or P2563)
• Loss of engine power and increased black smoke emissions
• Unusual burnt smell after regeneration

Causes can be short urban trips, interrupted regeneration cycles, or damaged hoses near the throttle valve.

If the DPF or engine light is on, it indicates soot or ash build-up that needs attention:

• Perform a forced regeneration using a diagnostic tool to safely burn off soot
• Drive at sustained highway speeds (2000-2500 rpm in 4th gear for ~30 minutes) to allow passive regeneration
• Inspect hoses and throttle valve for damage or dirt and clean if necessary

Ignoring these steps can cause turbo damage or complete DPF blockage.

To keep your Dodge Journey's DPF in good condition, follow these practices:

• Regularly drive on highways at elevated engine speeds to enable passive regeneration (at least once a month)
• Use specialised DPF cleaning additives added to fuel to help dissolve soot deposits
• Clean or service the throttle valve and replace damaged hoses promptly
• Avoid frequent short urban trips that prevent full regeneration cycles

Consistent maintenance can prevent costly replacements and ensure compliance with emission standards.

Forced regeneration is a process performed via diagnostic tools like Starscan that monitors soot levels and ensures safe exhaust temperature for complete DPF cleaning. This process:

• Is necessary when the DPF soot load exceeds about 50%
• Resets soot level to near zero, recovering engine performance
• Should be done by a professional or a garage equipped with suitable tools

It prevents expensive damage to the turbocharger or engine and restores the filter's efficiency.

If the DPF is irreparably clogged or damaged, replacement is the only solution. Considerations include:

• Replacement price starting around €1068, varying with workshop and parts
• Availability of brand-new high-quality DPFs compliant with emission regulations
• Professional installation is recommended to ensure correct fitment and functioning
• Removing the DPF is illegal and can lead to fines and vehicle impoundment

Always seek certified parts and professional fitting for warranty and compliance.

Additional resources include online Dodge forums, technical guides, and reputable parts suppliers specializing in Dodge Journey DPF references.

• Search for recent forum discussions using keywords like "DPF Dodge Journey 2.0 CRD P2002 regeneration" or "DPF replacement cost Journey"
• Consult professional garages with diagnostic tools for precise analysis
• Use reliable dealers for genuine Krosfou DPF parts with warranty and support

Always prioritise up-to-date and verified information for best maintenance and repair practices.

Remember to respect legal requirements and environmental standards when dealing with your vehicle’s emissions system.
