Nothing to say that there cannot be other causes.. but I have cleared pebbles out of the heatshield and that reslolved the issue.
Sometimes backing up and stopping rapidly will clear them but oftentimes not....
Thanks, going to try the hard braking method tonight and see if it clears it

Last night I was driving through Brooklyn behind a beat up nasty ass Van and I heard all this tin can dragging sound coming and I thought "that can is gonna explode from being so shitty"

then the van turned off and I still heard the sound!!! fast forward to this morning and I'm sitting in a traffic jam hearing the same sound. It sounds like a tin can tumbling around or otherwise known as the 'cowbell sound'

I haven't been able to do any proper hard braking because I have a coffee in the car...lol. but I just read about this one here. Has the hard braking solved it for most of you?

this is one of the most irritating sounds ever!!! LOL

Yes I always got them after autoX. Especially after a spin out. The crap flies around when you are doing the 1M rear end shuffle!

I had that and it went away. I think it was a small stone in the brakes. Went away after fast run.

Glad it worked but my method of hitting the brake shield might still be better. I had a rock lodge on pad in the rear and put a huge deep score in the rotor. Probably would affect much but it looked ugly!

ahhh yeah maybe! although i had no idea exactly where it was coming for----but it most likely must have been one of the shields or head shield.

at least i had fun getting it out! lol

This has happened to me twice. Pebble stuck between brake and shield. I just take a hose and blast in between the rotor and shield, Clears it up right away.

This just happened to me. I was driving normally when I had to pull over and take a phone call and when I parked on the curb and was on the phone I couldn't concentrate on my conversation because I kept hearing the "cowbell". I'm trying to reproduce the event but only have about a 40% success rate. I can reproduce it with better success by backing up slowly and coming to a stop. I can literally put it in P and it will just go on for hours! I waited it out for like 5 minutes and it never went away. Then I just drive off like normal and it is gone???

Oh well, I'm not overly concerned with it as it seems to just be some normal abnormality but it is annoying as $H1T

So not dealer worthy?

I just had this happen the other day, also while autocrossing, after about 4-5 runs. Took me a while to figure out the sound was coming from my car when moving through grid.

While removing the rotor, I had to give some whacks with a hammer and while doing that I heard a pebble hit the floor. Turned the rotor and the sound was gone. Removed it anyway to have a look, no marks on the rotor surface.

Grinding sound

I had a grinding sound coming from the rear on sharp right turn in low speed. Went to dealer they said it's the differential. They put in oil and said wait 1000miles. If it doesn't go then they might replace it. Anyone get this?
