Problems:
Oil leaks
BMW engines, particularly V8 engines, are known for developing oil leaks over time. This is often due to deteriorating gaskets and seals.
Timing chain issues
The timing chain can become loose or stretched, leading to poor engine performance and potentially severe engine damage if not addressed.
Fuel injector problems
Fuel injectors can get clogged or fail, causing misfires, poor fuel economy, and rough idling.
Carbon build-up
Direct injection engines are prone to carbon build-up on the intake valves, which can lead to reduced engine performance and increased fuel consumption.
Cooling system failures
Components like the water pump, thermostat, and radiator can fail, leading to overheating and potentially severe engine damage.
Turbocharger failure (alpina b7)
The turbocharged engine in the ALPINA B7 model may suffer from turbocharger issues, such as bearing failure or wastegate problems.
Electrical issues
