Hey M Team,
Thanks to the infamous "cowbell" thread, I diagnosed my own problem has to do with the e-brake adjustment spring (it sounds very springy). It happens too frequently when the tire is barely rotating to think something got caught inside.
I attached the audio if you're curious:
1) Is it safe to drive the car in the meantime? Obviously this only happens at very low speeds.
2) Is there anything I can do on my own to stop the sound, at least temporarily?
3) What do I tell my dealer/tech to fix this properly, rather than claim it's the service bulletin "natural sounds" ?
Thanks guys and gals!
