    Preface: in my 2001 Z3 I installed an AUTOMATIC (brand) OBD reader which sent information to my iPhone via Bluetooth. I was informed if the system pulled a code. Installed in a socket on the passenger side of the central console and used successfully for several years before I finally sold the...
  2. E46 (1999 - 2006)
    I've been able to capture a deep rumbling sound emitting from behind the dashboard's instrument cluster in the referenced video. It seems to be right behind the headlight controls. It is present for about 5 seconds immediately after starting the car, and then disappears completely before...

But I had an oil change 4 days ago, just today my 2011 323i started making a humming, I refer to it as an electronic sewing machine noise when I'm at an idle and at low rpm.

  6. E90/E91/E92/E93 (2006 - 2013)
    I didn't see anything about this but maybe I missed it in a search. It doesn't seem to bother my BF but it bothers me LOL I hear a hum coming from I believe to be the engine, this started maybe a couple months ago. Usually when I first start the car until the engine is nice and warm, say first...
