Engine: N55
N55B30A · 535i · Used in this car from 2011-2017
Strengths
Engine is widely used
Good potential for chip tuning
Watch-outs
Frequent vacuum leaks
Oil and coolant leaks
Some parts are very expensive
Known engine issues
Injectors and High-Pressure Fuel PumpEarly production engines used a short-lived HPFP from the predecessor, causing many issues. A more reliable pump appeared only in March 2012. Injectors were electromagnetic from the start and have no particular problems.
TurbochargersThe BorgWarner turbo lasts long with regular quality maintenance. Main owner complaints are about rapid wastegate valve wear and actuator failure (both versions).
Timing ChainThe chain itself has decent life, stretching after 200,000 km. However, its plastic guides are very sensitive to overheating and can crack. Engines before 2012 often had bolts shearing on VANOS units.
Listed from most frequently reported, each with its source.
Oil filter housing gasket leak and brittle plastic intake/pressure pipes
Often reported
The oil filter housing gasket, especially on N55 engines, tends to degrade and leak. Leaks can spill oil onto the front engine bay and pulleys/belt tensioner; there is a risk of plastic parts being drawn into the oil pan. Additionally, the plastic intake manifold and pressure pipes on some N55 units are known to be brittle, which can cause pressure loss, air leaks, engine faults, or performance loss.
Engine Bay
Cooling system: thermostat and leaks
Often reported
On F10 six-cylinder engines, issues may occur in the cooling circuit with the thermostat or other components (pump or hoses), leading to coolant leaks or temperature control malfunctions.
Cooling
Injectors and Ignition Coils: Misfires and Irregular Ignition
Often reported
Repeated reports indicate that injectors or ignition coils may fail with age/use, causing misfires, check engine light, and power loss.
Engine Bay
Oil leaks from valve cover/gasket
Often reported
Oil leaks from the valve cover or gasket are very common on N55 engines. The plastic cover can deform or crack over time, and the gasket hardens causing leaks. Leaks can reach the exhaust manifolds.
Engine Bay
High-pressure fuel pump (HPFP) failures
Often reported
On some N55 engines (including F10 535i), the high-pressure fuel pump (HPFP) can fail, causing starting and performance issues.
