Engine reliability and common problems:
The main problems with the N62 engine are related to malfunctions in the Valvetronic and VANOS systems. Fluctuating idle is usually caused by ignition coil failure, air leaks, MAF sensor problems or problems in the Valvetronic system.Another common problem is increased oil consumption due to valve stem seal wear. Typically, oil consumption problems start around 100,000km, with worn valve stem seals being the main cause. After a further 100,000km the oil control rings often fail.
Oil leaks from the generator housing gasket and crankshaft seal are also common.
As mileage increases, debris from a deteriorating catalytic converter can be sucked into the cylinders, causing significant damage. To minimise problems and extend engine life, it is essential to use high quality oil and fuel and to carry out regular maintenance.
Overall, this engine can last around 280,000 to 480,000 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.
