This point:
After engine warmed up sounds like exhaust manifold leak at low rpm, especially with heavier throttle. This is just the way a high revving v8 with awesome factory headers sounds down low. You'll learn to love it after you realize there's nothing wrong with the car. Does this sound like a ticking noise under acceleration from like 1000-3000k? |

some sort of panel rattle from the rear driver side... sounds like its coming from the seatbelt butler, but not sure as I'm always driving when it happens!

So recently I've heard this ticking noise -- and it's not the typical valvetrain noise that I'm accustomed too. The sound seems to be linked to RPM as well (second video)
To top it off, I've noticed little drops of clear liquid under the car (not water, somewhat oily)... looked underneath, car is soaked. Any ideas? |

I know some S65's have this noise from 2007 and they are still running , so you should not be worried about it . One thing is for sure.....DD don't have the cold start clunk noise .

I have an '09 6MT and just noticed tonight it is making a noise from 4k - 5.5k rpm (or higher but exhaust is too loud to hear it) on both acceleration and deceleration and it sounds like it is coming from the engine bay. I warmed the car up and ran it up to 6k or so rpm in second gear then let off the accelerator and it makes a noise that is hard to describe both during acceleration and deceleration. Maybe the best description would be the sound of crinkling up dry leaves in your hand. It makes the same noise in third gear but at those rpm's I'm going too fast for the road I was testing on.
Any ideas? |

Ha! I just revived an old thread about this because it annoys the crap out of me.
http://www.m3post.com/forums/showthread.php?t=853056 The sound from the video in that thread seems much louder than mine but it's the same sound...also when I rev in neutral there is a flickering/fluttering sound on decel.

Just bumping this to see if anybody else has noticed something like this? It's nothing like the regular valvetrain noises I hear on these cars. Totally random, but still speeds up as I rev the engine... |

This sounds like possible rod bearings to me. I am sorry if you posted but what's the year / mileage?

Ash, from what I have heard from a pile of videos that doesn't sound like rod bearings which has a more distinct knock.
There are a number of threads incl investigations with ticking noise very similar to yours - that turned out to be harmless. Do a search on the forum and you'll find them Im sure. Ps. Heres one for you but again there are plenty: http://www.m3post.com/forums/showthread.php?t=1167323 Last edited by Helmsman; 12-02-2016 at 10:20 AM.. |

Reminds me of chain slap sounds on the E39 M5 S62 motors. Perhaps it's your chain tensioner?

Not sure if already posted in this thread but I did not want to read all 12 pages...
Not normal: Whining sound coming from engine bay when making hard turns or sometimes just coasting. Solution: Power steering fluid is low. |

That's a big job and shouldn't create a sound like that.

Interestingly he told me they never had a blown motor m3, unlike the m5 where they had replaced several motors. He thinks they may have only did one or two bearing jobs on the m3, and he has been working there for over 5 years. |

I cant thank you guys enough for this thread. Just bought a 2013 e92 M3 and am coming from a 2011 e92 335i.
MUCH different car. All of the noises had me concerned, especially the drivetrain noise. The only other thing I noticed was a much more pronounced road noise around 65-80mph. Even my fiancé noticed it right off the bat. This car has the 19" ZCP wheels with Michelin pilot super sports (like my 335 did as well). Carbon fiber roof. 34xxx miles. Anyone else experience this? |
