Well I got my four majorly bald tires replaced today, so I don't have to worry about my tires blowing out on me.
But this had no effect on removing the tapping noise I've been hearing for the past two months. When I took my car to Sterling BMW, the techs there said that the dangerously-thin tires were what was causing it, but alas that doesn't seem to be so.
The noise sounds like a quiet tapping on metal noise. It's very fait so I can't hear it when I'm driving fast. But it's almost always there. I can't seem to make it go slower or faster. It's a low, almost constant tapping.
I'm thinking it might be some sort of metal fatigue or something, because it KIND of sounds like the noise you hear after you've driven your car for a while on a hot day and then pull over and stop.
The noise is coming from the back of the car, I think behind the driver's side and possibly below the car. Anyone have any guesses on this? I'm goign to get the alignment fixed tomorrow and hopefully that might fix it, but otherwise, I can't spot anything that might be causing the tapping noise.
