My 2001 330ci developed an odd rattling sound a couple of days ago, coming from inside the transmission tunnel. It sounds like it's coming from directly below the cupholders & armrest, and only happens when going over a bump, and is worse the more significant the bump is.
@bhdproduction2007 yeah, it actually turned out that the e-brake assembly on both sides was failing, so the shoes were scraping the drum. The sound was being carried through the driveline and carrying through to the transmission tunnel. Pretty odd, but once I replaced the e-brakes it went away.
(P.S. the "ConoverBMW" account is inactive now, and "ChristiaanConover" is my new account)
