Engine: N52
N52B30A · 130i · Used in this car from 2009-2011
Strengths
Good torque at any RPM
Well studied by our workshops
Watch-outs
Many problems in early engines
Cylinder block has no liners
Very sensitive to oil quality
Known engine issues
Scoring and oil consumptionThis engine has an alusil coating instead of cast iron liners and is demanding on fuel quality, plus there is no external fuel filter, so scoring and oil consumption are common. Early 2.5L engines had thin piston rings that quickly stuck.
Vanos and ValvetronicThe variable valve timing systems are sensitive to oil change intervals. Valvetronic malfunctions often lead to camshaft journal wear, and Vanos phasers wear out quickly when their valve filters become clogged.
OverheatingThis engine is very afraid of overheating and the cooling system must be monitored. High temperatures destroy gaskets and cause severe oil leaks, especially from the valve cover, oil filter housing with heat exchanger, and oil pan.
Listed from most frequently reported, each with its source.
Oil leaks from valve cover and oil filter housing
Often reported
Oil leaks from the valve cover gasket can enter the spark plug wells, causing misfires and damage to ignition coils. The oil filter housing gasket can also harden and crack, leading to oil loss from the front of the engine.
Engine Bay
Intermittent electric water pump and electronic thermostat
Often reported
The N52 engine uses electronic cooling circuit components (electric water pump and electronically controlled thermostat) that can fail intermittently or permanently.
Cooling
Valve cover gasket / integrated PCV leak
Often reported
On N52 engines, the valve cover and gasket, especially plastic versions with integrated PCV system, can deteriorate or crack, causing oil leaks.
