Alfa Romeo Brera Diesel Particulate Filter DPF (2006-2010)

The Alfa Romeo Brera Diesel Particulate Filter (DPF) is a crucial exhaust system component designed to reduce particulate emissions from diesel engines. It is compatible specifically with the 2.4 JTDM CF4 engine (engine code 939A9000), which produces 209 hp (154 kW), for Brera models manufactured between 2007 and 2010. This DPF complies with the Euro 4 emission standards and holds E-mark certification for the European market.

The original equipment (OE) part numbers compatible with the Alfa Romeo Brera DPF include 51780158, 51786867, 51797130, 51767239, and 51832671. For replacement filters, comparable references such as Bosal 097-202, EEC AR6008T, and Walker 73150 can be used. Always ensure to verify compatibility with your vehicle’s details before purchasing a replacement DPF.

The DPF system regenerates in two main modes to clean soot build-up inside the filter:

• Active Regeneration: The system artificially raises the temperature of the DPF to initiate soot burning and self-cleaning.
• Passive Regeneration: This occurs automatically based on parameters such as the DPF’s temperature, differential pressure, soot load (typically starts at 76% filling), and engine operating conditions.

The regeneration process is monitored by onboard diagnostics to keep the filter clean and efficient, thus maintaining vehicle performance and reducing emissions.

Various professional diagnostic applications and tools can monitor and report in real time on:

• The DPF soot load percentage and clogging level
• Filter temperature
• Pressure differential across the DPF
• History of regeneration cycles

Such diagnostics enable timely maintenance and help avoid DPF-related engine anomalies or warning lights.

A common issue is the illumination of the DPF warning light, which often indicates excessive soot accumulation requiring regeneration. Another typical problem is failure of the DPF pressure sensor, which may trigger error codes such as P2085. Troubleshooting steps include:

• Performing a precise diagnostic using a professional code reader
• Replacing the faulty pressure sensor if needed
• Resetting the DPF system with a professional diagnostic tool (e.g., Multiecuscan) after sensor replacement to avoid malfunction warnings

Proper diagnosis and servicing are essential for maintaining DPF function and vehicle compliance.

Certified new DPFs carrying the E-mark certification are available as replacements. These filters come with mounting hardware, detailed installation instructions in PDF format, and legal homologation certificates upon request. Benefits of these filters include:

• Compliance with ECE Regulation 103 revision 1 plus Amendment 1
• No vehicle re-registration or fiscal changes required
• Manufacture by European factories specialized in exhaust technology
• 24-month legal warranty with no obligation to return the old DPF

Choosing homologated quality DPF replacements ensures ongoing emissions compliance and vehicle performance.

Preventive maintenance involves regular monitoring of regeneration parameters and adapting driving habits to favor natural regeneration cycles. Key tips include:

• Avoid frequent short trips that prevent the engine reaching optimal temperature
• Use diagnostic tools to monitor DPF soot load and regeneration status
• Follow recommended service schedules and timely address warning lights

This approach helps maintain a clean DPF and extend its service life in Alfa Romeo, Fiat, Lancia, and Jeep vehicles equipped with diesel particulate filters.

Reliable DPFs and technical support can be obtained from specialized suppliers and manufacturers who offer certified original-quality filters made in Europe. Additional resources include:

• Technical support teams accessible for installation guidance and diagnostics assistance
• Online tutorials and video guides explaining DPF diagnostics and replacement
• Automotive owner forums and clubs where Alfa Romeo Brera owners share experiences
• Certified workshops and Alfa Romeo dealers equipped with professional diagnostic tools

Purchasing from reputable sources ensures high quality products with warranty coverage and compliance with European regulations.

Note: Always provide full vehicle details when ordering parts to verify compatibility.
