I am new to this community, as I just got my 2008 A5 about 2 weeks ago. Unforunately, I have an issue. For some reason my MMI works totally fine, but I am getting no sound out of the speakers regardless of if it is the phone, the radio, a CD, or the IPOD. It shows its playing on the screen, but you cant hear anything out of the speakers. If anybody has any idea about what this could be please let me know ...
did you get your windows tinted? I heard of problems where water used on the rear window leaked into the electric guts and basically fried the stuff I forget if there is some kind of mute button on the wheel. If all else fails, take her to the dealer. Everything should be covered still
I am having the same problem with my S5. It happened first a few days ago and then the problem went away. Today, the problem with no sound from the speakers has returned.
So, no one has heard of this issue?
Note that I have had nothing done to my car, including the windows. This problem seems to have just started to happen on its own.
Speakers not working .. MMI is ?
I forget if there is some kind of mute button on the wheel. If all else fails, take her to the dealer. Everything should be covered still
