Abnormal oil consumption in the 550i's N63 engine (4.4 V8 turbo) is widely reported, requiring frequent oil top-ups.
Engine Internal
Due to direct injection and N63 characteristics, injector clogging/failure and ignition issues lead to misfires, power loss, and rough running. Direct injection also causes carbon buildup on intake valves.
Fuel System
The high-pressure fuel pump in the N63 engine is critical; failures can cause rail pressure loss, hard starting, stalling, and limp mode.
Fuel System
The N63 engine's turbochargers and gaskets can develop issues: oil leaks into intake or exhaust, degraded gaskets/seals, and wear on turbine components, causing exhaust smoke, power loss, or abnormal noises.
