Hi all, my 2007 A6 C6 2.0 TDI has only very recently started to give me a little trouble....after all these years. The left hand side speakers are only working....with the radio but not the right side speakers...but all the speakers work when i am using the bluetooth for the phone. It makes no sense. I've checked the balance and the settings and restored the settings to "Default" but no success. any ideas. Many thanks
