Strange Engine Humming High Pitched Please Help!

G80M3andMe · 01-31-2023, 05:15 PM

Hi all,
Have a strange sound coming from my engine, I know the tick tick tick is from my fuel pumps, but I’m talking about the whining sound, sounds like piss hitting the porcelain bowl, or a truck backing up beeping away.

Still have no idea what this could be, I hope it’s not serious…

It doesn't really matter if its serious, unless you've voided the warranty. I'm going to say it sounds like a pulley, but, it's really hard to tell with a dark video of a noise.

I have an Eventuri Intake, JB4 with no tune applied (never have only using it as a diagnostic tool in real time,) High Flow GESI Catted Down Pipe and Crossover pipe by Evolution Racewerks, and VSC-II exhaust valve controller. Did I void the warranty? 😰
I’ll take another video in the daytime.

With all of that installed. I’d be making sure it just wasn’t an aftermarket exhaust part squeaking against something. You may just need an exhausts adjustment.

Yeah, thats weird. You can hear it better with the camera away from the fuel pumps. Like in the :30 range. The only thing I know that sounds like that harmonic pitch, is a pump, pulley, or bearing. Not fuel pump, more like a compressor.

My friend says it sounds like the intake sucking in more air and is more like an intake hum. Idk 🤷&zwj;♂️ This is a 2023 and it shouldn’t have the bad bearings from the 2021 model year. It only has 2500 miles on it. 😓it’s 36 degrees if that means anything.

Definitely possible it could be the intake whistling.

Does the pitch change if you feather/stab the throttle?

The S63 makes a similar sound when there's a vacuum leak due to a cracked vacuum hose.

I’ll make another video and check it out.

Were those sounds there before all these mods?

It’s hard to recall clearly if I’m being 100% honest. I don’t think so, I honestly believe that noise came as a result of the eventuri intake that was installed by my local BMW dealership.

Did you ever figure out what's causing this I have the same issue

Nope can you post a video link to your sound?

Betsken1 · 04-15-2023, 08:48 AM

Here is a link to a video with same harmonic humming sound

I created the video this morning ...my car has no mods and just over 2k on it for miles

forcefed · 04-15-2023, 10:09 AM

There's too many noises coming from the engine, to say one is normal the other isn't, isn't exactly easy.

I have the same sound. 2023 M3 G80 Comp Xdrive and no mods. Car has only around 2.5K miles.

I think it is a vacuum sound. I tried my friend's car but it was normal. Mine has this high-pitched sound. Any solution yet?

Sadly no. But if enough people comment and share their experiences we can have BMW investigate rather than blow it off.

G80M3andMe · 04-15-2023, 08:16 PM

Does anyone know where to even begin finding the vacuum lines?

Here's another video from today with the hood closed. You will have to turn volume up
