So I've have my 335d about 3 weeks now. Driving to work this morning, I started hearing a humming sound that started around 60 mph and faded out about 75, peaking in loudness at about 70. The sound only changed with speed, not rpms. Also, I don't feel a vibration or anything through the steering wheel.

The sound wasn't a constant hum at the same pitch, but the pitch went up and down. Does this sound like a wheel bearing? I tried to take a video to get the sound but my phone only picked up the road noise.

What kind of tires does it have?

I've also noticed that when I turn the wheel left the pulsing sound gets faster and when I turn to the right it gets slower or goes away.

Sounds like wheel bearing, left the front end, and spin the wheel as fast as you can and see if you hear it, also grab the tire at 12 and 6 oclock and see if you have play.

Thanks. I'll jack it up in the morning and give it a spin.

Bringing this thread back. OP did you find out what the issue was? I think I am experiencing the exact same thing as you described, I'm getting a pulsating humming sound at highway speeds but only when I'm turning left and it gets faster the harder I turn. Going straight and right everything is quiet. I'm thinking it may be the front right wheel bearing but there is no play in it when I jacked it up and pulled on the tire. The only sound I hear from it is the pad rubbing on the rotor.
