Infiniti M Diesel Particulate Filter DPF 3 (Iii) (2010-2014)

The Diesel Particulate Filter (DPF) is a vital exhaust system component in Infiniti M Diesel vehicles. It filters fine particles and soot emitted by the diesel engine, preventing harmful pollutants like nitrogen oxides, hydrocarbons, and aldehydes from being released into the atmosphere.

The DPF consists of a porous ceramic substrate through which exhaust gases pass. The ends of the filter are blocked, forcing gases through the substrate walls that trap harmful particulates but allow gas to flow.

The filter accumulates soot over time, and when efficiency drops, the engine control unit (ECU) triggers a regeneration process to burn off the soot, either by raising exhaust gas temperature or using catalytic substances.

Common issues include progressive clogging of the filter, which reduces exhaust system efficiency. Causes include a low fuel tank, defective sensors, clogged EGR valve, or low exhaust gas temperature.

• Constant engine warning light
• Black smoke from exhaust
• Loss of engine power and performance

A buildup of ash on filter walls increases backpressure and further reduces engine performance.

The average lifespan of an Infiniti M Diesel DPF is between 150,000 km and 180,000 km if regular regeneration is maintained.

• Drive regularly at high and consistent engine speeds to enable natural regeneration
• Use recommended fuel additives to assist soot combustion
• Keep the exhaust system in good condition and promptly address faults

Following these guidelines helps extend the filter's service life.

Professional cleaning is the most effective method, offering a quick turnaround (2-3 hours) and performance restoration without altering factory engine settings.

• Requires dismantling the unit and specialized equipment
• If soot levels are too high, replacement might be necessary

Note that dismantling the DPF is illegal as it would make the vehicle non-compliant with environmental regulations.

For quality and reliability, choose new Infiniti M DPFs made from stainless steel with high-grade ceramic monoliths, certified to meet or exceed manufacturer and European standards.

Online stores specializing in genuine automotive parts offer models with 3-year warranties and free shipping options, backed by return policies you can agree with for worry-free purchases.

• Search for parts compatible with your engine and model

Indicators of a clogged DPF include:

• Engine warning light stays illuminated
• Noticeable black smoke from the exhaust
• Reduced engine power and sluggish performance
• Unusual exhaust backpressure detected during diagnostics

If you suspect clogging, consult a professional mechanic for diagnosis and appropriate cleaning or replacement.

Reputable sellers generally offer a free return policy within 30 days for unused and unmounted Infiniti M DPF spare filters in original packaging. Always check and agree to the specific return policy before purchase.
