The NISSAN NV400 dCi 125 is a popular commercial van known for its practicality and versatility. Designed for demanding work environments, it's commonly used by tradespeople and couriers, so likely your van has seen plenty of action and hard graft! This guide provides key information about its common issues, maintenance needs, and what to watch out for to keep your NV400 running reliably.
Owners sometimes report injector failure, turbocharger problems, and premature wear of the dual-mass flywheel, typically around 120,000-180,000 km. Keep an awareness of these potential issues with your NV400 as it ages.
When taking your NISSAN NV400 dCi 125 for a Warrant of Fitness (WOF) inspection, be particularly mindful of potential issues that can lead to failure. Pay close attention to excessive play in steering components, as this is a common reason for failing an inspection. Also, address any rear brake binding or inefficiency and make sure to remedy any oil leaks from the engine or transmission before bringing it in for inspection.
Because your NV400 is a workhorse, a regular maintenance regime is particularly important.
Maintenance Matters:
Keeping up with scheduled servicing for your NV400 dCi 125 will help extend its lifespan and prevent major issues. Regular checks should include fluid levels (oil, coolant, brake fluid), filter replacements (oil, air, fuel, cabin), and inspections of brake pads, rotors, and tyres.
Potential Issues to Consider:
Like any vehicle, the NV400 dCi 125 has some known weak spots that owners should be aware of. Keep an eye out for potential injector failure and turbocharger issues as the mileage increases. Premature wear of the dual-mass flywheel is another area where owners sometimes experience problems.
When investigating issues, areas of the vehicle to focus on are, for example, the INTERCOOLER, BALL JOINT FRONT LOWER or STARTER MOTOR.
Other common parts related to vehicle maintenance are the HEATER CORE, DISC BRAKE ROTOR REAR, OIL SEAL CRANK SHAFT FRONT / TIMING FRONT, CYLINDER HEAD GASKET and CYLINDER HEAD.
If you are experiencing a problem with the clutch, potential components to investigate are the CLUTCH SLAVE CYLINDER, CLUTCH FLYWHEEL or ADVANCED CLUTCH SYSTEM. Consider inspection of the CV JOINT FRONT OUTER and SUSPENSION BUSH FRONT CONTROL ARM during regular maintenance.
Also, OIL SEAL CRANK SHAFT REAR / REAR MAIN BEARING and AIR CONDITIONING BLOWER ASSEMBLY issues should be investigated immediately.
