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

The Diesel Particulate Filter (DPF) is fitted on diesel versions of the Alfa Romeo Spider, mainly produced from 2006 to 2011, that meet Euro 4 emission standards. Common diesel engines with DPF include:

• 2.4 JTDM (engine codes 939A3, 939A9; 200 hp / 147 kW) from 04/2007 to 03/2011
• 2.0 TD MJTD (engine code 939B3000; 170 hp / 125 kW; 1956 cc) from 2009 to 2010

These DPFs are sometimes combined with catalytic converters to reduce fine particle emissions effectively.

Key technical features of the Alfa Romeo Spider DPF include:

• Weight: approximately 7.3 kg
• Length: 735 mm or 760 mm depending on supplier
• Material: Silicon Carbide (SiC), suitable for vehicles equipped with On-Board Diagnostics (OBD)
• Compliance: Euro 4 standard, E-Mark certified, and meets European pollution regulations
• Function: integrates a second catalytic converter and the DPF monolith impregnated with precious metals for efficient particle filtration
• Installation kit often included for easy replacement

This design ensures effective reduction of harmful diesel exhaust particles while maintaining vehicle performance.

Official OEM part numbers include 51780158, 51786867, 51797130, 51832671, 51767239, 51831548, and 1370425080.

Compatible aftermarket references come from manufacturers certified for quality and fitment, ensuring compliance with the original specifications and emission standards.

Always verify your vehicle’s engine code and production year to select the correct DPF item.

High-quality DPFs for the Alfa Romeo Spider are available from specialist automotive parts suppliers focusing on emission control components. These suppliers:

• Offer products manufactured in Europe with certifications such as E-Mark and Euro 4 compliance
• Provide kits including mounting hardware for easy installation
• Ensure warranty coverage, typically up to two or three years on European manufactured parts
• Support recycling of the old DPF to recover precious metals, following environmental regulations

Check with professional dealers for advice on selecting the right part for your vehicle and engine type.

DPF lifespan depends on driving conditions and maintenance, but generally:

• DPFs do not have a fixed replacement interval; they are designed to last several years or over 100,000 km if properly maintained
• Frequent short trips or slow urban driving can cause quicker clogging
• Regular high-speed trips help the DPF to regenerate by burning off accumulated soot

If the DPF warning light appears on your instrument panel, or if performance drops with increased fuel consumption, professional diagnostics should be conducted to assess whether cleaning or replacement is required.

Cleaning the DPF is possible if it is clogged but not damaged. Professional DPF cleaning services include:

• Thermal cleaning to burn off soot buildup
• Ultrasonic or chemical cleaning to remove ash deposits

However, if the DPF has physical damage or permanent blockage, replacement is necessary.

Regular maintenance and correct driving habits improve the regeneration process and extend DPF life.

Ignoring DPF problems can lead to:

• Reduced engine power and increased fuel consumption
• Frequent warning lights including the DPF warning indicator on the dashboard
• Potential damage to the exhaust and engine components
• Possible failure to pass vehicle emissions tests due to higher particulate emissions

Addressing DPF issues promptly ensures optimal performance and longevity of your Alfa Romeo Spider’s diesel engine.

To prolong your Alfa Romeo Spider’s DPF lifespan, follow these recommendations :

• Drive at sustained highway speeds regularly to trigger automatic DPF regeneration by burning off particles
• Use the correct oil and fuel quality as specified by Alfa Romeo for diesel engines
• Ensure timely servicing and engine checks to avoid issues causing excessive soot
• Avoid frequent short trips that prevent the DPF from reaching regeneration temperature

If the DPF warning light comes on, have the vehicle inspected without delay to prevent costly repairs.

Professional advice from qualified dealers or service centres is recommended for the best maintenance practices and genuine spare parts suited for the Alfa Romeo Spider diesel DPF system.
