Nissan 1.5 dCi
Renault-Nissan 1.5 dCi diesel engine — fitted in millions of vehicles. Fundamentally solid, but EGR valve and injectors are weak points.
Economical diesel
The 1.5 dCi is frugal and has enough torque for everyday use. Not a sports engine, but reliable.
Engine Weaknesses 6
The K9K high-pressure pump can generate metal swarf that contaminates the entire fuel system. Pump, all four injectors, fuel lines, and tank must all be replaced.
Symptoms: Engine failure, starting difficulties, black smoke, metal particles visible in fuel filter.
The K9K timing belt can break prematurely if the injection pump is not correctly aligned. Misalignment causes the belt to fray at the edge and snap well before the replacement interval. Engine damage as it is an interference engine.
Symptoms: Belt noise, visible edge wear on timing belt, sudden engine shutdown
The K9K EGR valve clogs with soot deposits, especially during frequent short-trip driving. A stuck valve causes power loss and increased consumption.
Symptoms: Power loss, rough running, increased fuel consumption, check engine light with EGR fault code.
The K9K DPF does not regenerate sufficiently during frequent short-trip driving and clogs up. First problems often arise between 50,000 and 80,000 km.
Symptoms: DPF warning light, power loss, black smoke, regeneration cycles fail, vehicle enters limp mode.
The K9K charge air hose splits frequently, especially on older build years (FE0C version). Newer FE1C versions are more robust. The hose often tears at clamps or pinch points.
Symptoms: Sudden severe power loss, hissing noise under load, increased fuel consumption, check engine light.
The K9K camshaft sensor fails repeatedly from around 100,000 km. Sporadic starting problems and rough running are the result. Aftermarket sensors often last only a short time.
Symptoms: Sporadic starting problems, engine misfires, check engine light, occasional stalling
Vehicle Weaknesses 5
The Note E11-FL front coil springs also break from around 90,000 km. Same design as the pre-facelift, same problem.
The cables in the tailgate transition also break on the Note E11-FL from constant flexing. Number plate light, rear window heater, or reversing camera stop working.
The blower resistor also burns out on the Note E11-FL. Fan only works on high speeds. Same issue as the predecessor; easy replacement.
Water also enters the E11-FL boot through the porous third brake light seal. Slightly improved over the pre-facelift, but not fully resolved.
The standard radio display in the Note E11-FL becomes unreadable or goes completely dark at temperatures above 25°C. A facelift-specific issue. Replacement display (SA1245) available as a DIY solution for around €50.
