ticking sound from front (dash / engine)
With the stereo off, and driving 'sanely' with the family we here a rapid constant ticking sound coming from the front of the car. My wife says it sounds like crickets. It's only there under low-mild acceleration (when everything else is quiet enough to hear it), I'm sure it's there as well under greater acceleration but then everything else is making more noise. Anyhow the sound instantly disappears when you take the foot of the accelerator. So I'm thinking it's injector sounds or something like that. The frequency of the ticking doesn't seem to increase with rev's or speed. It's just an annoying sound, albeit a quiet one. Do any of the rest of you hear this sound? If it's a common M5 sound I'll forget about it, otherwise aarrgghh.

Does it sound a bit like static? I had this on my earlier F13 M6 and it was related to the symposer and as such was coming out of the speakers. That was more like static though, although could be called a ticking sound at a push!

Is the symposer the unit that makes the 'exhaust' sound? If so I've disabled that via coding, but that may still be the cause. Static to me is a random sound, this is more like a buzz, perhaps around 20-30Hz but with a higher frequency. Always present except for when the accelerator isn't touched. And it sure sounds like it comes from the front of the car.

when u start your car tomorrow morning (cold start), come out of a car and stay next to the front left wheel, i think it is coming from there it disappears when engine is warm enough, at least on mine, after 15-20 minutes of driving i dropped my car to bmw yesterday, i should have an update tomorrow, as i want them to look at few bits and pieces around a car if they did not forget about it, i will let you know what they have said for me it sounds like some pulley not sitting properly or it wears out |

but they are so sneaky in BMW... i keep complaining about suspension clunk and this time they told me: we looked at it and it is your exhaust touching a suspension, but luckily my new SA is very chilled and he said they will change it, after main M technician took a look at it will keep you posted in regards of that noise Last edited by mstmng; 10-18-2013 at 01:48 PM.. |

In regards to the 'fake' sound turned off, the car is a lot quieter now although there is still the drone from the transmission. You really need to open the windows now to hear the exhaust sound. I do wish that it could be enabled/disabled easily or only have it come on when in Sport+ mode or something like that. There are times when the ego wants to be larger than it is - if you know what I mean

I'm going to try to record the sound and play it back at the dealership when I'm in on Tuesday for my 2000km break-in inspection. The sound is loudest at 1500 rpm, and you have to be driving. I can't hear it will parked.

May be totally unrelated but the x3 had something similar, sounded like rustling paper at the base of the windscreen, and was really annoying.
Turned out to be the cover under the hood below the windscreen, the rubber seals were squeaking against the plastic. Some people padded it with foam to stop it until BMW accepted there was a problem then there was a fix with some other rubber stuff (sorry don't recall what they used Maybe totally unrelated but figured id share |

brainblade...did you ever figure out what is causing this noise? I have the same noise:
-engage gas pedal....ticking noise @ constant frequency, does not vary with speed -disengage gas pedal...ticking noise stops after a brief (half second) delay this occurs 100% of the time. |

also are you running catless or stock downpipes? and can you hear it if you rev your car in neutral? Last edited by mstmng; 11-09-2016 at 03:25 PM.. |

stock downpipes... I don't remember hearing it in neutral...likely because not enough boost is being created to spin up the turbines and cause the noise. |
