Am I Paranoid? New engine click/rattle

So I was waiting in a line in my car this evening, and heard a noticeable click while it was idling. I move forward, and the click goes away again. Finally got home, and heard it again, so I took a video. Note that the clicking rate increases as I rev it lightly.

Like many, I am quite paranoid with any noise from this engine, though my understanding is that rod bearings are also known as the "silent killer". For reference, the car is an '08 with 47.2k miles on it. I am thinking I will try and get some time with the dealer. Any thoughts?

Rod bearings swapped or not?

You need to take a video near the engine bay, there's not much to tell from your video posted above.

Yeah, went down to my car and tried to get another video with the hood up. Didn't really hear anything this time, and the fan covered any potential noise it was making. I'll try taking another video before heading to work tomorrow, from a cold start.

Could't tell anything from the video even at full volume.

Your 08 should have lead/copper bearings. Have you had Blackstone analyse the oil? I would get onto that asap if you're concerned about the bearings.

Updating, working on uploading two videos but my work internet is piss poor. No noise with the engine cold, but with it warmed up you can hear something. Most importantly, I learned that if you push the clutch in, the noise disappears entirely. With it up it comes back. In the engine bay, it is difficult to hear, but seems to be coming from the back of the engine. It is much more audible from inside the car.

This is all making me think its clutch related. Maybe something rattling against the slave.

My 08 6spd did the same thing, it's just a noisy transmission don't worry about it.

Yep sounds clutch related. BMW revised the clutch and flywheel design in late '09 builds to help remedy some of the noise. Your 08 will have slightly more noise than later models.

I can hear something . But a video in cabin .. C'mon are you serious man ?
Video is useless .Warm up your S65 and take the damn cam close to the driver side front wheel and revv it slowly up to 3K rpm's .
Repait this 3 X .

That's reassuring. My Dad just got an 08 with 15k miles on it. I'll check if it makes the same noise.

I'm definitely intending to do a Blackstone analysis with my next oil change. I am planning on doing rod bearings next year, but we'll see what the analysis says.

For the sake of posterity, here are the videos I took, this time not in an enclosed space:

Haha, I know . I was just in a hurry to catch some of the noise, and had dinner waiting in the car.

When I bought me E92 ( and after reading about the RB's) I would get paranoid for every clicking, rattling sound that comes from the engine. Even my wife thought I was acting weird , every now and then bending down near the wheel arch, popping the hood to listen closely to those sounds.
Then I decided to do the RB's...now I couldn't care less of any sounds...just drive it like it should and enjoy the car.
Yeah, I know it's just psychological...but at least I'm enjoying the car as how it should be.
