Yea i was just at a Thai restaurant in Los Angeles (sanamluang) and i saw a White M3 with Akyrm front bumper and large round sticker looks likes an MFEST member, right off he started the car it made the sound... now i dont feel too bad i actually heard it on someone else's car. LOL

In some cases, it could be also be unburned fuel inside the cylinder and when the car starts the fuel ignites and creates a start up knock. If this is happening, the car will start a bit differently as well, as it will sound like it took less cranks to actually start the engine.
Either way, it's nothing for you to be concerned or worried about. It's going to be very difficult for any dealer to replicate this sound for you unless they are starting the car multiple times a day for many days until they finally encounter it. At that point, they will only believe you on the sound, by no means does it mean they have diagnosed it.
My suggestion is to not worry, as there isn't anything wrong.

Thanks but i really hope they find it. i know its normal since everyone is stating that it is, but to be honest i really just want them to find out the cause. just an FYI i guess.
This is the 3rd time i brought it in with the same problem. so hoping this time they actually diagnosed the issue.
Ill do another thread if it they do find out the cause.
