Ignition coil failure

Ignition coils can fail over time, leading to misfires, rough running, and reduced engine performance.

Intake manifold gasket leaks

The intake manifold gasket can deteriorate, causing vacuum leaks that result in rough idling and poor acceleration.

Crankcase ventilation system problems

Issues with the crankcase ventilation system can lead to excessive oil consumption and rough idling.

Electrical issues

Older BMWs can have electrical problems, such as faulty sensors, wiring issues, and failing control modules, affecting engine performance.
