Sound on unlocking and brakes acting funny
 
325xi 02 116k
Anyhow, when I unlocked my doors today I noticed an odd little buzzing noise. It only happens when I unlock them, not when I lock them, and it happens everytime. They never fail to unlock, the noise is just unnerving.

Brakes:
Replaced pads and rotors about 2 months ago due to warped rotors causing vibrations when braking. Maybe 3 weeks afterwards I got a slight vibration back in the breaks, and now it's nearly back to where it was initially. On top of that, my breaks squeal a bit when I press lightly on them as if the pads were in need of replacement. It's my understanding that pads should last longer than 2 months.
Ideas?

The R.I.F. Principle....(Reading Is Fundamental)

The term is "BRAKES", Skippy, not "breaks", which is something altogether different. If you had done a little homework, you would have found that rotors *rarely* warp, and your problem is probably either suspension-related, or pad deposits built up on your rotors. Try bedding the brakes again.

I inherited the car with the "warping" issue. And I apologize for the misspelling my overly sympathetic friend, it's 1am here and I've just gotten done with work (on a business trip, not home). I was told that it was "warped" rotors when I got the car so that's what I reported the problem as, as I had no idea. Also RIF == RTFM, but I suppose that's a less kind way of putting it. & I appreciate your response despite its caddish nature. I'll be sure to do more research in the future.
Post fixed for your pleasure. ;)

the unlock buzz is most likely the unlock relay built into the GM module. if it still works leave it alone.

I would have the front suspension inspected. sounds like the thrust rod bushings are worn to me.
