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 

If it's been bought from the dealer within the last 30 days, you have the right for a full refund. The dealer has to resolve this for you. 

Hi Steve . Thanks for the reply.  I'm hoping that they will come up with a solution in the next couple of days or that is where the fun and games will start otherwise. 

Hi, I’m having the same problem with my Audi A3 2010. Did you figure out what was causing this ?

Hello Tommy,

Probably better to send Paul a PM. 
Kind regards,

Gareth.
