Anyone get this noise sometimes. Im sure it is a pebble from the road getting betwween the brake disc and the metal guard behind the disc. It has happened occasionally with every car ive had (once in 2 years maybe) but I get it 2 - 3 times per week with my A5. Im figuring it must be down to the design of this gaurd and I notice it is aerodynamically shaped (to aid brake cooling I presume) whereas all the other cars ive had never had this aerodynamic design to the guard.
Typically there is only a couple of mm between guard and brake disc but with the unusual design there are some larger gaps on the A5 allowing stones easy access perhaps.
Anyone getting this?

Is your car stock e.g. lowered, custom wheels, etc.?
Its not lowered and has not got spacers or anything like that fitted. Its running genuine 18" rims with factory spec tyres.
The noise isnt a wheel rubbing. It just happens randomly. It sounds as though there is something caught under the car when it happens but the noise then dissappears and can then appear again later. Its only when rerversing and wheels can be straight or turned, it makes no difference. Im 99% sure its a pebble around the brakes but then everyone should be finding this.
