Engine reliability and common problems:
The primary issues with the N62 engine are related to malfunctions in the Valvetronic and VANOS systems. Fluctuating idle is usually caused by ignition coil failures, air leaks, issues with the mass airflow sensor, or problems in the Valvetronic system.Another common problem is increasing oil consumption due to the wear of valve stem seals. Typically, oil consumption issues start around 100,000 km, with worn valve stem seals being the main cause. After another 100,000 km, the oil control rings often fail as well.
Additionally, oil leaks are frequently reported from the generator housing gasket and crankshaft seal.
At higher mileage, debris from a degrading catalytic converter can get sucked into the cylinders, causing significant damage. To minimize problems and extend the engine’s lifespan, it is essential to use high-quality oil and fuel and to perform regular maintenance.
Overall, this engine can last around 310,000 to 520,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
