Oil Leaks:
Valve cover gasket, oil filter housing gasket, and oil pan gasket can leak due to age and material degradation. Crankshaft seals can also fail.
Valvetronic System:
Eccentric shaft sensor failure or worn intermediate levers can cause rough idling, misfires, and check engine lights on N52 engines.
Ignition System:
Ignition coils and spark plug boots can fail, leading to misfires and reduced engine performance.
Power Steering:
Hydraulic power steering fluid leaks from hoses or the steering rack are possible. "Whining" noise from the pump can indicate low fluid or an impending failure.
