E90 N47 engine vibrations
I've got some engine vibrations when running idle. Not sure if engine should vibrate like this or not
The vibration's frequency is quite high, hard to capture on video. Instead, you only see the engine cover moving slowly in the video. But in fact it vibrates very quickly
When removing the cover, the engine itself vibrates even quicker, so on video it looks still.
I wonder what the cause might be and where to start looking for it.
