Problems:

Oil leaks
BMW engines, particularly the M54 found in the 2001 525i, are notorious for oil leaks, often from the valve cover gasket and oil filter housing gasket.
Cooling system issues
The cooling system components, such as the radiator, water pump, and expansion tank, tend to fail over time, leading to overheating.
Vanos problems
The variable valve timing system (VANOS) can suffer from issues, including rattling noises and performance loss, due to worn seals or solenoids.
Crankcase ventilation system failure
The crankcase ventilation system (CCV) can become clogged or fail, leading to poor engine performance and oil consumption.
Ignition coil failure
Ignition coils in these models can fail over time, causing misfires and rough engine performance.
Mass air flow sensor issues
The mass air flow (MAF) sensor can become dirty or fail, resulting in rough idling, stalling, and poor fuel economy.
Fuel pump failure
The fuel pump may wear out and fail, causing the engine to run poorly or not start at all.
Oxygen sensor failure
Faulty oxygen sensors can lead to poor fuel economy and increased emissions.
Intake manifold gasket leaks
The intake manifold gaskets can deteriorate and cause vacuum leaks, leading to rough idling and poor engine performance.
Thermostat failure
The thermostat can fail in the open or closed position, causing the engine to overheat or run too cool.
