Nissan NV400 Catalytic Converter (2010-2024)

The Nissan NV400 catalytic converter is an essential exhaust system part designed to reduce harmful emissions from the vehicle’s diesel engine. It is primarily compatible with the 2.3 dCi 170 HP diesel engines (motor codes M9T 706, X62B EV HV0L UV0L) produced between 2010 and 2024, including SCR (Selective Catalytic Reduction) versions for Euro 6 compliant models post-2016.

The Nissan NV400 catalytic converters vary by engine and year but key details include:

• For NV400 2.3 dCi 170 (X62B EV HV0L UV0L) SCR Diesel models (2016-2018): dimensions approx. 1750 x 650 x 220 mm, weight 12.6 kg, priced around €765 new.
• Other NV400 diesel models (2010-2024) use standard diesel catalytic converters with various motor codes and variable pricing.

They function to reduce NOx, CO, and hydrocarbons using ceramic substrates coated with rare metals, often integrating AdBlue injection for SCR models ensuring compliance with Euro 6 emission standards.

Common symptoms of catalytic converter failure include :

• Metallic noises coming from the exhaust system
• Decreased engine power and performance
• Increased fuel consumption
• Engine fault codes such as the P0420 (catalytic converter efficiency below threshold) detected via OBD diagnostics

These signs often indicate internal clogging or damage to the ceramic substrate and require professional diagnosis for accurate assessment and repair.

Price details are as follows :

• New catalytic converters for the NV400 Van 2.3 dCi 170 are approximately €765.
• Used or scrap converters’ value depends on the condition and precious metal content such as platinum, palladium, and rhodium, typically ranging from around $276 to $395 USD (approx. €250 to €360).

Specialized dealers provide quality compatible products with warranty and proper fitment assurance according to engine codes and dimensions.

Reliable sources include specialized distributors offering original or high-quality aftermarket catalytic converters with manufacturer specifications. It is essential to verify the engine code and vehicle VIN before purchase to ensure a correct fit. Technical support and installation manuals are often available through professional suppliers.

• Confirm fitment by referencing the vehicle’s motor code
• Seek products compliant with European E24-103R certification to guarantee quality and legal standards
• Consult technical support via email or specialized forums for troubleshooting and installation guidance

Key points include :

• Standard shipping times range from 1 to 6 working days within Europe, with express delivery options available.
• Free returns are typically accepted within 30 days for unused and original packaging conditions, subject to company policies.
• Most new catalytic converters come with a 3-year warranty covering up to 100,000 km usage, provided installation and maintenance guidelines are followed.

Customers should verify shipping terms and conditions with the dealer or factory directly and keep packaging intact to qualify for returns or warranty claims.

The catalytic converter in the NV400 works by catalyzing chemical reactions that convert harmful exhaust gases like nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC) into less harmful substances such as nitrogen, carbon dioxide, and water vapor.

• Diesel versions often integrate SCR technology, using AdBlue to further reduce NOx emissions, meeting stringent Euro 6 emission norms.
• The catalytic converter contains a ceramic or metallic substrate coated with rare metals that facilitate these reactions.

This system is critical to vehicle emission control and environmental protection.

Proper care can extend the catalytic converter's lifespan :

• Regularly check and replace engine components that affect emissions, such as oxygen sensors and Lambda sensors, typically after 80,000 to 100,000 km.
• Avoid short trips that do not allow the engine and catalytic converter to reach optimal operating temperatures, as this can lead to soot buildup.
• Use only unleaded fuel and follow manufacturer recommendations regarding fuel and oil to prevent contamination.
• Ensure proper installation using correct gaskets and connections and avoid any damage during removal or replacement.

Ignoring these can lead to clogging or failure, voiding warranties and increasing repair costs.
