Sound just popped up this evening and I only drove it half a block further as I spoke with BMW Assist. They're coming to pick it up in the morning and take it to a shop to see what it is. I'm out of town on vacation, so we'll see how good that vacation policy to reimburse for food, rental, and lodging goes.

Yea, def let us know. I'm one that travels a lot.


Good luck.

Maybe a wheel-weight came unglued and lodged in between caliper and wheel?

Hope whatever is an easy fix.

When they came to pick it up, I was reversing the car to get it on the platform and I heard a click, then the screeching sound went away. Been driving all day and haven't heard it again. No idea.

Perhaps some road debris got wedged between a brake disc and caliper. Backing up would dislodge it. Maybe a stone or something. Did you check your brake disc on both sides for scratches or gouges?

This happened to me with my Mk5 GTI a few months ago.

The cause was ALMOST CERTAINLY a rock between the pad and rotor in one of my brakes. horrible sound, none of the electronic picked up anything. no spilt oil. Was 5 minutes from flat bedding until the sound went completely away.

there was no mark on my rotor ( could have easily been the back of the rotor btw).

The chances of metal-metal wear without an oil slick or the car sitting funny is odd. For me i could rev the engine as much as i wanted, only screeched on car movement. I just walked around kicking the tires to dislodge.


Scared the shit out of me and was a major reason for selling the car ( realization that i didn't want to eat into my new car fund fixing a car with expensive VW parts...)

Well that was bust of a post - no closure.

Above is the end. No change.

Definitely a rock in the caliper. If it happens, usually you can dislodge by reversing like you did.

Had this happen to me twice - once with my Honda Accord in the late 90s and again just a few years ago with my girlfriend's Sonata. Really awful sound both times, plus the Sonata had it happen late at night in the middle of a rainstorm. I thought it was rock vs. rotor, so I had her pull over under an overpass so I could diagnose it.

I was bending down near the front left tire where the noise was, asked her to back up slowly and then pull forward again so I could listen for the sound to confirm it and see if the direction change would fix it. She has a lead foot and ignored the "slowly" part. Would up backing up 25 feet so quickly that she nearly ran me over. Great night all around!

Thing is, I reversed and drove forward a good bit before letting the car sit overnight. First reverse in the morning when it cooled down did it, though.
