Recently purchase an S3 8P with all sat nav, ICE upgrades and have developed a problem. Had a loud high pitched noise come from the speaker system some weeks ago & couldn't stop it, eventually it did of own accord.

What i have been left with is an issue with bluetooth or the voice control system where by my phone will connect but keep dropping out and no sound coming through speaker system (when i press voice control button on steering wheel it mutes sound but again nothing from speaker system).

Had the car plugged into VCDS which gave the following info:
