I have a 2011 E92 m3, around 35K and it has Ohlins R/T coilover installed around 12/25/2015. (I don't know if it's a coilover related problem, but just trying to provide a little more information here).
So the problem is my car is making a tap noise(It's not constant, usually one tap or two) when I'm turning the steering wheel, and it also happens when I release the brake and hit the gas at a stop sign/light. I think it happens more often when the car just started. Anyone has experience this before? People said its most likely from sway bar endlinks, I'm going to let my dealer check it out tomorrow.

I just made a tight left turn and heard a loud click, can someone explain the process they do to fix it and how much it will cost.

If it's coming from the rear, it's probably your diff. It's not actually harming anything, but if you want to get rid of it there's an additive they put in. Not sure about cost, but it's not substantial.

Doesn't the diff sound that's fixed by the additive sound like the rear wheel rubbing on the wheel well? That's what it sounds like in mine.
Definitely not a click. |

Thanks for this post. Just got myself into a 2008 m3 (yay!) and was wondering about all the noises! Glad to hear most of the noises I hear are relatively common and normal for the car.

I have a helicopter sound when coasting/cruising but not when clutch is in neutral (6MT), i am scratching my head. The sound frequency is that of the wheels but my understanding is that the clutch throw-out bearing always rotate at engine shaft speed (RPM) whether clutch is disengaged or not. But that's not the frequency of the sound i hear. But maybe it is more subtle like the bearing traveling axially on its axis back and forth under axial load. How much work is it for the dealer to take a look at the clutch ? my car is under factory warranty.

As for the helicopter sound. It is normal. Your ///M is an high reving, high speed concept, means certain parts are developed to operate in normal everyday driving AND track abuse. There are higher tolerances on some parts as they, very primitive explained, shrink at some point and extend. Your helicopter sound comes from an part that is in extended condition. Again my apology for the very primitiv explanation |

Well, why i care about dealer working on my car, any work done by dealers comes with the risk of errors and adding side issues. Since the car came straight to me from the factory unless i determine there is something wrong that necessitate a repair i am not so fast to let dealers explore my car. (+ they have a conflict of interest to work on the car as any warranty works gets paid to them by bmw) Last edited by Rajmun340; 05-21-2016 at 04:00 PM.. |

Hmmm... when I start her up cold, the engine starts -- and then I hear a loud "THUNK!" from the engine bay. Doesn't happen when the car's warmed up, and I start it, but at times, when I do start it warm, the same sound occurs, but muted.
Normal? Pre-rod bearing explosion? |

Hearing a small metallic clunk/ping when I put my car into first gear from a stop.
Is that just a normal driveshaft noise? |

Not sure if this is the noise you are talking about, but it used to happen on my e92. I was told it was the Vanos. Never seemed to negatively affect it and dealer said it was normal.

I'm "100%" sure you have the cold start clunk noise as well .. Vanos ? Indeed ,and caused by the "Vanos-Gears"

You should put a headphone on and turn up the volume and listen 10 X .. I've heard over the years probably more than 1000 clunk noises on Youtube and Bimmerpost . and S65 ticking and rattle noises as well, but from bearing failures from all over the world . I will receive this weekend 2 videos from the US to listen to S65's for abnormal noises. The base of the sound is always the same , sometimes it's louder than other days and it depends how long you didn't drove the car . Some have one loud clunk noise , others have the kind of a short rattle clunk noise that are actually 2-3-4 short clunk noises in a row . How longer I don't drive my car , the louder the noise will be ! But there is also the brake procedure for DCT's (pumping the brake pedal for 30 sec.) and it really helps preventing the noise because my car is DCT as well . The brake procedure helped several people on here as well , but it works not for 6MT . I heard clunk noises on here from videos ,and the owers didn't noticed it for over 3 years , I heard the video once and said to them...You have the clunk noise as well ! The answer was like...What noise lol The real fix are the Vanos-Gears , I saw only one case of a Vanos-Gears replacement and the owner never heard the clunk noise again ...Never ! The problem is that Vanos-Gears are not cheap ! It was a PUMA-case and here is the document of it . Please read point => " B " And ?

I have a light ticking, valve train noise on cold start that lasts about 2 minutes, maybe less. Doesn't happen everytime, most apparent after it sits for day. 56k miles. Also the rattle isn't consistent like a bad rod bearing. Only happens at idle and is gone as soon as I drive it. Doesn't come back till the next morning.

This may be hard to explain, but when I accelerate at fairly low speed 40-55 in 5-7th gear there is a more pronounced faint bell sounding noise that seems to come from the left side... Not sure if it is in the engine or coming from exhaust.
