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

The Diesel Particulate Filter (DPF) is installed mainly on Alfa Romeo Brera diesel engines, notably the 2.0 JTDM 163 CV (120 kW) and the 2.4 JTDM versions that comply with Euro 4 standards. These DPFs are often combined with a catalytic converter for emission control.

• 2.0 JTDM 163 CV (Engine code: 844 A2.000) – DPF weight approx. 7 kg, length 550 mm
• 2.4 JTDM CF4 (X4) 209 CV (154 kW)
• 2.4 JTDM 200 CV (147 kW), engine codes 939A3, 939A9, 939A3000 – DPF weight approx. 7.4 kg, length 540 mm (produced Jan 2006 to 2010 and beyond for some models)

The DPFs used on Alfa Romeo Brera models are new units typically made from silicon carbide for superior durability. They are Euro 4 approved (E-Mark certified) and often incorporate a second catalytic converter plus DPF to reduce fine particulate emissions.

• Weight ranges between 7.0 kg and 7.4 kg
• Length varies between 540 mm and 550 mm
• Material: Silicon carbide for long-lasting performance
• Configuration: Single pipe or combined catalytic converter and DPF unit

This ensures effective reduction of diesel particulate matter and compliance with emission standards.

Several specialised online retailers offer new, Euro 4-compliant DPFs compatible with Alfa Romeo Brera diesel engines, including:

• 2.0 JTDM 163 CV specific DPFs
• 2.4 JTDM CF4 (X4) 209 CV DPFs
• 2.4 JTDM 200 CV combined catalytic converter + DPF units

When ordering, ensure to provide precise vehicle details such as VIN and engine code to verify compatibility and confirm the correct DPF model.

The DPF requires proper regeneration through normal driving conditions and speeds to prevent clogging. Replacement frequency depends on vehicle use and maintenance but typically occurs after extensive usage or when regeneration fails.

• Regular monitoring for smoke emissions or warning lights is recommended
• Professional diagnostics can inform if cleaning or replacement is necessary
• Frequent short trips or city driving can increase the likelihood of DPF fouling

Replacing or servicing the DPF promptly is vital to maintaining engine performance and reducing harmful exhaust emissions.

Some vehicle owners contemplate DPF removal due to issues like increased exhaust backpressure, DPF clogging, or to improve performance and fuel consumption. However, removing the DPF is illegal in many regions and may cause increased smoke emissions and legal consequences.

• DPF removal can adversely affect the vehicle’s emission control system and compliance
• Modern DPFs also help reduce visible exhaust smoke significantly
• Proper DPF maintenance and timely replacement is the recommended approach

Always consult a qualified Alfa Romeo garage or exhaust specialist before considering any modification to the exhaust system.

The total cost for fitting or replacing a DPF can vary depending on the parts, labour and the specific model of Alfa Romeo Brera. Genuine new DPFs offer the best durability and performance but may cost between 2,000 to 4,000 € including fitting in garage estimates (subject to variation).

• Costs include price of the original DPF, catalytic converter if combined, and installation
• Using a trusted garage ensures correct fitting, sensor calibration and system regeneration
• Extra costs may come from diagnostics and possible EGR system checks

Contact an authorised Alfa Romeo specialist or exhaust expert to get a detailed quote and ensure proper fitting.

DPF regeneration is the process by which trapped particulate matter in the filter is burned off to prevent clogging and maintain exhaust flow. This typically occurs through elevated exhaust heat during sustained driving, especially at highway speeds.

• Regeneration can be active or passive depending on engine management system
• Proper driving at normal speeds and with adequate engine load supports natural regeneration
• Failure to regenerate can lead to warning lights, reduced performance and smoke emissions

Driving your Alfa Romeo Brera regularly at suitable speeds helps maintain the DPF and avoid costly repairs.

If the DPF warning light on your Alfa Romeo Brera activates, it indicates the filter may be clogged or the regeneration cycle has failed. Take the following steps:

• Drive your vehicle at steady higher speeds (above city speeds) for 15-30 minutes to allow regeneration
• Avoid frequent short trips or excessive idling which can cause soot build-up
• If the light remains on, visit a professional garage for diagnostics and possible DPF cleaning or replacement
• Also check the EGR system and sensors related to exhaust emissions

Ignoring the light can lead to further engine damage and increased fuel consumption, so prompt attention is advised.
