Name that rattle
2012 e92 n55 60k. This is my brothers car. Can you hear that rattle when throttle is very gently applied? Sounds like it’s from under the valve cover. Also, are n55’s this noisy?
What do you think? https://youtube.com/shorts/R33YrvRsLYY?feature=share |

The injectors are noisy. In the stock form, they also perform multiple injections to keep the noise down and idle happy.
This is why you can hear it go back and forth between standard clicks, then jumping around. I'm sorry if this did not answer your question. I couldn't hear anything else. However, I can promise with the cover back on, this shouldn't be an issue. |
