Hello all,
It's been a few months that I have purchased a beautiful 640i coupe.
I was scared to buy a used bmw, but thanks to the helpful community we have here I had the courage and purchased one.
Everything has been fine for the past months, but recently I get a humming noise when I turn the steering wheel. It doesn't ALWAYS happen, but mostly after driving in city for a while (I drove a 3hour journey on the highway and the sound wasn't there. The sound also happens when I turn the steering wheel when the car is off.
Here's the link of the video :
My car has an electric power steering wheel so, there's no reservoir to fill. I personally don't think there's a problem with the EPS because the noise is still there with the car off.
I have searched online for a few days, but nobody seems to have the same issue as me.
Any help or similar experiences would be very helpful (in the country I live, mechanics aren't very professional so I was hoping to know more about the issue before visiting one)
