Electric drain, and "wheel bearing noise" problems.

Sounds like the electronic parking brake is not releasing properly. Be worth checking that when you change the pads and disks.

A5/B9 front system noice – related to PreSence?
Bought the new A5 in the summer. Since the beginning I sporadicly hear a noice in the front left wheel, like two metals rubbing each other briefly. Occurs ad-hoc, maybe 1-2 times per 10km, usually when car starts and wheel has turned a couple of times already. Sounds a bit like the noice when PreSence is activated, less intence though. For the times I have deactivated it didn’t occur. In the attached audio it between seconds 4 and 5.
Tried to upload an Audio file where it is captured but I guess audios cant be uploaded. Has anybody experienced such a thing?
