If the model includes a turbocharged engine, turbocharger failure or wastegate rattle can occur, leading to reduced power and efficiency.

Timing chain problems

The timing chain in BMW V8 engines can stretch or fail, causing rattling noises and potentially severe engine damage.

Carbon buildup

Direct injection engines in BMWs can suffer from carbon buildup on the intake valves, leading to misfires, rough idle, and reduced performance.
