Noise from the rear when parked...

[Palmer]

This has happened a few times to me since ive had the A8.

Basically ill park the car up, lock it and then there is a very lound whining noise which if you follow, leads to the rear wheels. Its like a motor whirring. After around 10 seconds of whirring, you will hear the handbrake apply, and then also release. Now i dont use the handbrake i just leave it in park, so i dont think its an issue with the handbrake - which i may add also works flawlessly in traffic when i leave it in D.


A bit of googling has lead me to me believe that the rear pads re-seat every few thousand miles so they sit closer to the disc, and the whirring is the pads adjusting.

Is this correct or is my car a little bit broken haha
