Engine Noise - BMW 3-Series (E90 E92) Forum

ybbiz34 · 09-29-2008, 12:49 PM

I don't know if I'm just paranoid/especially sensitive lately or what but I've noticed that while at idle after driving for a while, or cruising between 20-40 mph, it seems as if engine noise has increased (vague, I know). No real difference in sound/new noises, just louder. Even with music cranked up fairly loud, I can still hear it. I'm guessing this is insignificant but I'm just throwing it out there for comments.

also just throwing it out there, but, maybe the radiator fan is working harder?

Hmm, interesting. I don't know why it would be though?

Well, it needs to cool your engine, more... the oil is getting hotter, but so is your engine. No?

I guess I was asking why all of a sudden an issue like that would arise, if it had never been present before.

I feel bad no one else is answering, I'm sorry I don't know more about the inner workings of the N54

Now that you mention it, the noise does seem to resemble a drone, but I really feel as if it is coming from the engine bay.

Did you finally break-in the exhaust? A/C compressor going, maybe?

I figure it has to be something irrelevant. I need to get out of my own head. I actually enjoy the fact it is louder now, so I don't even know why I came on here whining about it.

People with the new PRrgram updates complain of the car getting louder? can you say for sure it has gotten louder?

NPDAN · 09-30-2008, 12:04 AM

Just overall more engine noise or does something stand out a little more then before?

I am not sure what part of the country you live, but as crazy as it sounds, it seems like our engines really thrive under cooler ambient temperatures. I have noticed that my engine runs and sounds better as temperatures cool off; say close to 50 degrees or so.

I'm pretty darn sure it has. Although, no program updates here.

More overall noise. Low-pitched, almost as if it is exhaust drone.
