Excessive cam gears noise

Hi folks!

Got a quick question.
I know that cam gears make that whiny noise. It was very subtle when I first got the car. Now at 6000km the noise is much more pronounced to the point that this is the only thing I can hear driving in first few gears at lower RPM's.
At highway speeds no issue.

I am wondering whether it's normal for this noise to get louder over time (break-in). Are there any factors affecting it, such as outside temperature, etc?

Hard to tell from your description. Check the power steering fluid level. I had a loud, roaring noise when the car was cold that was due to the power steering fluid level.

Not sure if this is your case but when I first got my car at 35k I noticed that it whined quite a bit more than my e46M. From what I gather, it's normal.

I would not be alarmed in case it was consistent.
Will try to record it.

try changing your fluid... thats always the cheapest alternative before pulling everything apart.

You mean power steering fluid?

Do a search on power steering fluids and see if others' description sound like yours. That's how I figured it out for me. Every time I took it to the dealership the sound was gone. It was probably because the fluid was warmed up and circulated. Just a thought, it might be something else.

The cam gears do make some noise. I've had a few people ask me if the car is supercharged due to the cam gear whine.
