Cam gears whining sound?

So i've been trying to figure out what the whining sound coming from the engine bay is and i believe it is the cam gears. I was able to find some info on the forums but not a whole lot about this topic

I was wondering if you guys can take a look at my descriptions below and give your opinion on whether it is the cam gears

- whining sound coming from engine bay area

- sound is similar to supercharger whine or that whining sound from your transmission when you accelerate quickly in reverse or that "feedback" sound you get with aftermarket stereos OR that whining/whirling sound of a high speed RC car

-sound is evident both while stationary (idling) and moving (on the throttle)

- sound volume goes up and down in relation to amount of throttle

- sound is very noticeable in 1st and 2nd but less prevalent in 3rd gear and higher

- sound is independent of steering

- sounds like it is coming from the left side of the engine bay when you are standing at the front of the car (passenger side)

- i'm not an expert but do know my way around cars and in my opinion it doesn't sound "offensive".... meaning it doesn't sound like something is broken...of course i know that these sounds can be quite tricky

The sounds of sweetness! When I see other local m3s that the signature sound. Must drive 335 guys nuts that their cars' engine sound is anemic in comparison. Lol!!!

...love the sound of gear drive vs old timing chains, etc. Unique sound for this engine that most who own recognize from a distance.

Yah I actually prefer my sports/sporty cars to be noisy, just wanted to make sure it's not the bad sort of noise i'm hearing

I love how the car sounds really raw on a cold start

Just to provide an update since I know a lot of people wonder about the whining sound.

I took the car in to the dealership to have the hood latch adjusted recently and asked them about the whining noise. They said the noise was normal.

Now whether or not they can be trusted (or if they even know what they are talking about)... well that's up to you to decide.
