Problems:
Oil leaks
Older BMW engines, including the 1988 528e, are prone to oil leaks from various seals and gaskets, such as the valve cover gasket, oil pan gasket, and rear main seal.
Overheating
The cooling systems in these engines can be problematic due to aging components like the radiator, water pump, thermostat, and coolant hoses.
Vacuum leaks
These can cause rough idling and poor performance; common sources include aging vacuum hoses and intake manifold gaskets.
Timing belt failure
The M20 engine in the 528e has a timing belt that needs regular replacement (typically every 60,000 miles) to avoid catastrophic engine damage.
Fuel system issues
Problems with the fuel pump, fuel injectors, or fuel pressure regulator can lead to starting issues, poor performance, and fuel inefficiency.
Electrical problems
Aging wiring and connectors can lead to intermittent electrical issues, including problems with the ignition system and engine sensors.
Carbon build-up
Over time, carbon deposits can accumulate on the intake valves and combustion chambers, causing reduced engine performance and efficiency.
Idle control valve failure
The idle control valve can become dirty or fail over time, leading to erratic idling and stalling.
