A rough idle in a BMW M6 can be caused by a variety of factors, including dirty fuel injectors, a faulty oxygen sensor, or a clogged air filter. It's important to have a certified mechanic diagnose the issue so that it can be properly fixed.

Another common cause of rough idle in a BMW M6 is a malfunctioning mass airflow sensor. This sensor helps control the amount of air entering the engine, so when it becomes faulty, it can cause the engine to idle roughly. I would recommend getting this checked by a professional as well.

In some cases, a rough idle can also be caused by a vacuum leak. This can occur when there is a crack or hole in one of the hoses in the engine. If you suspect a vacuum leak, be sure to have it repaired as soon as possible as it can affect the overall performance of your car.
