buzz sound
MY-2004 E320,
This morning, when I unlock the car w/ the remote. I heard this buzzing sound from the front-right side of the car lasted around 3 seconds.
Was wondering if anyone has experienced this.
No malfunction is displayed.

The SBC unit?
If by front right, you mean the passenger side on a LH drive vehicle, then the SBC brake pump may have come on. It does when the door is unlocked. Search for SBC and you will find about 5,000 entries for it on this forum. Noise from it is normal, even with engine off.
If you know what the SBC is and what it sounds like and you are talking about something else, let us know.

Thank you Ozusa,
That's what I thought, even though the car wasn't even started.
I didn't know that SBC would engage even though the car was just sitting there.
The buzzing sound reminded me of a car I had w/ some sort of active suspension and I know this E320 doesn't have one.
Once again, thank you for the info.
