Hi all. Ive only just joined Just bought an a3 2011 S Line with the audi navigation plus. . I have a problem with the sound system in the car. The front center speaker and the small speakers in the window pillars work. The front door speakers only work at high volume levels but the sound is distorted. The rear door speakers don't work at all and the sub in the boot does not appear to be working. I think its the standard audi music system in the car. Has anyone else had this problem. Any advice would be greatly appreciated. Currently trying to resolve the situation with the dealer i bought it from but don't think its going to be easy to resolve with them at the moment
