"Is the 5 Serisi 530i reliable, and what should you check?"
When buying a used BMW 5 Series 530i 2012 (F07 / F10 / F10M / F11), the most frequently mentioned issue is: oil leak from the valve cover gasket / spark plug tube seals (oil in spark plug wells). Also, carbon buildup on intake valves (direct injection) is commonly reported.

Strengths
Economical for this displacement
Torque across the entire rev range
Watch-outs
Many fuel system problems
Cylinder block has no liners
Very sensitive to oil quality
Known engine issues
Injectors and high-pressure fuel pumpMost engine problems are related to the high-pressure fuel pump and short-lived Siemens piezo injectors, which cannot tolerate poor-quality gasoline and can fail at low mileage. Also, this engine has no liners, and poor fuel can cause scoring in the cylinders.
Catalytic converterThe exhaust system is equipped with a storage catalyst and a nitrogen oxide sensor, which only regenerates during prolonged high-speed driving. Due to the high repair cost, owners usually remove this system.
Timing chain and camshaft adjustersWith regular and quality maintenance, Vanos camshaft adjusters last a long time, but only if their valves are cleaned and seals replaced every 60,000 km. The chain is also durable, but guide rail breakage sometimes occurs.

Oil leak from valve cover gasket / spark plug tube seals (oil in spark plug wells)
Often reported
A frequently reported issue: oil leaks from the valve cover gasket or spark plug well O-rings; oil enters the spark plug/coil wells, causing misfires, contamination of electrical components, and requiring replacement of seals or the cover.
Engine Bay
Carbon buildup on intake valves (direct injection)
Often reported
The N53 engine uses direct injection, so fuel does not clean the intake valves, leading to carbon buildup over time. This can cause reduced throttle response, rough idle, and may require cleaning.
Engine Internal
Spark plugs and ignition coils prone to wear and failure (causing misfires)
Often reported
Due to direct injection and injector/seal issues, spark plugs and ignition coils on the N53 engine wear out or fail more frequently than on other engines.
Engine Internal
High-pressure fuel pump (HPFP) failure
Often reported
The high-pressure fuel pump (HPFP) on the N53 engine is known to fail prematurely; it can cause long cranking, rough idle, loss of power, and entering limp mode.
Fuel System
Piezo injectors (leakage/clogging)
Often reported
The piezo injectors in the N53 direct injection system can clog or leak, causing misfires, cold start difficulties, and rough idle. In some cases, leaking injectors can wet the spark plugs or send excess fuel, leading to damage.
