Folks,
I've picked up a cold-start dashboard buzzing sound (video file below) that manifests itself for the first 2-3 minutes during all cold starts.
The engine does not need to start, nor do you need to turn the ignition on to initiate it. Just getting in the car and getting some power to the interior is enough to set it off.
Once the car warms up, it goes away.
Any ideas or suggestions on how to mitigate it, short of allowing the dealer to touch the car (which usually carries some downsides)?
TIA,
a
