I am just glad that I got a later 2018 that didn’t need the LCI software update. And yes, my MPE crackles and pops on downshifts. |

Dan, when was your car produced? Mine was produced in August and I took September '17 delivery and Im under the recall. Probably get it done next Sept when I bring it in for its annual paid-for oil change.. Not that I want it done, but they'll ram it down my throat. I hope by then we get some consensus as to whats going on with this snap-crackle-pop issue.

Mine was built 12/18/17. Picked it up April 9th. Not sure how long it was at the dealer's lot, but it was delivered to the dealer I purchased from.

Popped into dealer today. They told me the istep update can not alter the sounds the car makes!
Anyways, booked in for next week where we will compare my car to other M2's they have without the update. Can't wait to hear their explanation after this exercise. This was their idea btw so I appreciate their willingness to try to get to the bottom of this. |

What the hell is istep? I'm taking my 2017 for service next week and they better not touch the sound. It is 90% of the enjoyment for me. Here's my conspiracy theory: the N55 especially with MPE will blow away the sound of the upcoming Competition model. BMW doesn't want the latest greatest model to be upstaged so they are quietly (pun intended) neutering our cars. Fuck that I'll make sure there are no software updates done on mine.

There's a very long debate on the subject of software updates in the F80 forum.. Might be worth checking out. Firmware/Software Versions https://f80.bimmerpost.com/forums/sh....php?t=1261500 |

Guys why isn't this thread blowing up? This should be one of the most important issues to current M2 owners. What the hell is BMW up to? Are they neutralizing our cars to try and make the Comp a better sounding car? I want to hear from some heavy hitters. Artemis?

I'm gonna check my version since it's probably the updated one because it's a January build and I took delivery in March... and maybe it has subdued crackles and pops without my knowledge since it's the only M2 I've ever driven... could it have something to do with the new emissions regulations? : |

Because it's a non issue for many of us and so it seems like you guys are making something out of nothing.
Exhaust volume/sound is easily affected by air intlet temps, engine/oil temps, exhaust gas temps and ambient air temp, meaning your car will always sound somewhat different depending on a combination of factors related to temperature. I highly doubt it has anything to do with what version of istep you're running. I've gotten multiple istep updates and my car sounds identical. What (I think) they might have done is change the way the ASD is set up. It may be quieter now due to complaints of it being too loud (I assume), or maybe it's just a conspiracy to sell more MPE's. Who knows. I wouldn't know personally since I had ASD coded out but I think I remember reading that they did turn it down, so maybe what some people here are noticing is the ASD volume has decreased. That might explain why some of us (ASD Bypass harness/coding) haven't noticed any differences. |

Regardless of whether I'm right or not, if you have Tinnitus and the ASD is bothering you, you should buy a bypass harness or code it out with bimmercode. It's really not that difficult and It makes the cabin MUCH more peaceful and bearable to sit in. Don't be hesitant, just bite the bullet and do it. You'll thank me later. |

Re temperatures etc, totally makes sense that it would cause variation in sound but the difference is night and day. Compared to when I brought car in, it has warmed up considerably here since and car def popped and cracked more prior to visit. No doubt about it. I sincerely wish that I can come back here and say you were right all along. I have no problems with eating crow on this one... I want to do some more WOT runs this weekend to see if that changes things. |

Besides temperature, brand of exhaust may have an effect on sound changes over time. The constant heating up and cooling down causes the pipes to constantly contract and expand. Depending on the material and quality of one's exhaust system it could theoretically cause a sound change over enough time/miles. Curious what kind of exhaust everyone who's complaining is running and how many miles they've put on it. Maybe we'll see a pattern. |
