545i engine popping?itnis not
Hi guys,
I am looking for advice with my 545i, engine is doing some very quite popping noise from engine. I am able to hear the sound only in cabin, passenger side. The sound is connected with rpm. No codes present, no oil burning...nothing wrong with the car.
Here is video from youtube, it is not my video, only this video on YT nicely capture the popping sound and it is same. The popping sound in video is hear around left side of the engine, around vacuum pump.
thanks in advance

Sounds more like a bearing noise. Check the bearings (tension pulley ...)!
In the video is a comment regarding a clip which made the noise.

That is the right and not the left side of the engine (like your right hand stays your right hand even if you turn around) and it still sounds like a bearing noise to me (sound transmission from a broken bearing).
But if you do not mean the obvious bearing noise, why would you link especially this video and not mention it?

I am not sure if we understand each other. As I wrote, I have same "tap-tap-tap..." (time 0:14-0:35 in video, around vacuum pump) sound which is hear only in cabin. Not the squeek one, or "crunchy" one, but the harmonic "tap-tap-tap". And I am not able to say what cause it or if it is common sound of N62. I have not better video, only this one from youtube, where is problem with plastic clip...

Then that was a misunderstanding from my side. I don't know enough about the V8 to be helpful here.
