Hi All I recently bought an Audi A6 206, and have a problem with MMI. It restarting itself every few seconds. It goes as far as to welcome screen and restarting again. This doesn't stop even if I lock the car (I had to takeoff fuse). I did a scan with diagnostic tool (not vcds, just standard tool), and no errors. Non of the buttons are working except parking brake button. Did anybody had similar problem? Thanks in advance for any help.
