Hi guys, I have 03 325i non-sport

The issue Im dealing with for last year is grinding in suspension (or driveline?)
Most certainly it feels coming from front left (driver's) side

I manage to keep this noise at 45 miles speed and ~1900-2000RPM for video
Usually it happens when you start accelerating or while turning at slow to average speed and after highway when I exit and make an arc at 35-40MPH.
Also on the straight line as for this video (when I hit a small bumps, the loudness of sound changes as well)


Small vibration also goes into the cabin (pedal/seats)

Although Im new here, I have been reading e46 forums for a long time and couldn't find same issue.

Thanks for help!

Possibly wheel bearing? Jack it up and spin the wheel...it should spin freely if it is ok
Thanks for reply. Im sure Its not the bearing. The sound disappears immediately after throttle is released.

Sound comes at any gear, from 1850 up to 2100 RPM. If I keep RPM in this range, grinding stays, if I increase RPMs it fades away as well as releasing pedal. I was thinking about Vanos, but at idle, engine sounds normal, as well as revving on parking.
