Infiniti EX Diesel Particulate Filter DPF (2007-2014)

The Diesel Particulate Filter (DPF) in the Infiniti EX, especially the 3.0 d V9X diesel engine model (from April 2010), is an essential exhaust system component that captures harmful soot particles from diesel combustion to meet Euro 5/6 emission standards. It helps reduce exhaust pollution and ensures your vehicle operates within legal emission limits.

The DPF is designed for the Infiniti EX 3/5 door (J50) 3.0 d diesel model featuring the V9X engine, from April 2010 onwards. New genuine filters are available for this engine and comply fully with exhaust gas regulations.

The DPF traps soot and fine particles, which leads to clogging over time. Symptoms of a clogged DPF include:

• Reduced engine power and performance
• Increased fuel consumption
• Illumination of engine warning lights on the dashboard
• Possible black smoke emissions due to improper soot burn-off

Ignoring these signs can cause further engine issues and higher emissions.

The primary cleaning method is passive regeneration, which involves driving at a steady speed of 60 to 80 km/h for 25 to 30 minutes (ideally on a motorway). The high exhaust temperature burns off the soot deposits inside the DPF.

• If passive regeneration is insufficient, a garage can perform a forced regeneration using diagnostic OBD tools that activate active cleaning cycles, sometimes by injecting AdBlue or using heat.
• Preventative driving habits like avoiding short urban journeys help keep the DPF clean.

Regular checks and maintenance prevent costly replacements and maintain engine efficiency.

There are several options for replacement DPF parts and accessory kits compatible with the Infiniti EX:

• Pressure sensor kits and connector sets suitable for DPF and soot sensors, priced from around £19.
• Complete new DPF units for the Infiniti EX 3.0 d V9X engine meeting exhaust gas standards, available in stock with fast delivery.
• Premium quality DPFs tailored specifically for Infiniti models, ensuring durability and performance.

Always check item compatibility with your vehicle's engine and VIN to ensure proper fitment.

The DPF is integrated into the exhaust system, typically positioned downstream of the engine’s turbocharger and before the catalytic converter. It serves as the main filter to trap diesel soot particles before the exhaust gases exit the vehicle.

This location allows it to effectively reduce particulate emissions while maintaining proper exhaust flow and vehicle performance.

The cost for replacing the DPF varies depending on whether a new original part or a high-quality aftermarket unit is purchased, and the labor costs at your garage. Generally, the price range is from around £200 to £1500.

• Always ensure you buy an OEM or equivalent quality item for reliable emission control and engine performance.
• Costs may include VAT, delivery charges, and installation fees.

Consult your local garage or parts supplier for exact quotes based on your vehicle's VIN and engine specification.
