Alfa Romeo 159 Diesel Particulate Filter DPF (2005-2011)

The Diesel Particulate Filter (DPF) is a crucial component in Alfa Romeo 159 diesel engines (mainly 1.9 JTDM, 2.0 JTDM, and 2.4 JTDM models) that traps soot and particulate matter from exhaust gases, reducing harmful emissions to comply with Euro 4 and Euro 5 standards. It is often combined with a catalytic converter to improve emission control.

The main compatible engines and versions include :

• 1.9 JTDM (120 HP, 1,910 cc) for models 2005-2011 (including Sportwagon)
• 1.9 TD JTDM DPF (120 HP) from July 2005 to February 2008
• 2.0 JTDM (136 or 170 HP) diesel engines meeting Euro 5 standards
• 2.4 JTDM Q4 CF4 (209 HP) Quattro or X3 versions

These filters are designed specifically for these engines with corresponding OEM codes and specifications.

Typical technical specifications include :

• Weight ranging between 5.8 kg and 7.4 kg depending on engine model
• Length between 450 mm and 735 mm
• Compliance with Euro 4 or Euro 5 emission standards
• Material composed mainly of silicon carbide with an integrated catalytic converter (secondary catalytic converter + DPF)
• DPFs often come with mounting kits for installation

These characteristics ensure effective filtration and durability suitable for Alfa Romeo 159 diesel engines.

The DPF does not have a fixed replacement interval, but it requires periodic monitoring and possible servicing depending on your driving conditions and engine maintenance :

• Regularly drive the car at motorway speeds to allow for active regeneration of the DPF
• If the DPF warning light appears on the dashboard, consult a professional for diagnostics
• Replacement or professional cleaning may be required if the DPF becomes clogged or damaged

Always follow your Alfa Romeo maintenance schedule and consult specialized garages or forums for advice on DPF care.

Indicative prices for new DPFs (excluding VAT) :

• DPF combined with catalytic converter for 1.9/2.4 JTDM engines around €279.90 (with discounts available)
• DPF alone typically ranges from €379 to €544 depending on OEM reference and engine model
• 2.0 JTDM versions priced around €420

Delivery times vary but stocks and quick delivery options exist. Prices are for new, original parts that meet quality and certification standards.
