The 3.0-liter Renault and Nissan V9X or 3.0 dCi diesel engine was installed from 2008 to 2015 and used in models such as Laguna, Pathfinder, Navara, and Infinity crossover cars. This diesel engine has gained a controversial reputation in our market due to its very expensive repairs. Currently, there is only one engine in the V-series engine lineup.

The weight of the V9X engine is 185 kg (without attachments). The V9X engine number is located between the cylinder heads. Due to very narrow crankshaft journals, the diesel engine is extremely sensitive to oil pressure, and any decrease in oil pump performance can cause the crankshaft bearings to rotate. There have been many cases reported of the oil filter seal ring getting into the oil pump, which often leads to engine failure. The oil consumption rings can become worn at around 100,000 km, resulting in oil consumption, but the worst-case scenario is if the compression ring gets pushed out and causes scoring on the cylinder wall. There are no repair sizes available for the pistons, and it is not possible to simply hone the cylinders. The timing chain often stretches after 100,000 - 150,000 kilometers of active driving. The kit is not expensive, but replacing it requires removing the entire power unit. The intercooler in this engine has a very modest lifespan and comes at a high price. Sometimes it can develop leaks at around 50,000 - 70,000 km, and welding doesn't provide a long-term solution. The EGR valve with an integrated cooler is quite expensive, and it tends to get clogged very quickly to a point where it cannot be cleaned. Fortunately, it can be deactivated.
