hello, last week I purchased a 2006 a4 2.0T Quattro with 60,000 km (about 37,000 miles for those of you in the US) despite all the reliability horror stories. everythings great so for except for my disc changer, which makes tons of noise (don't know if that's normal or not) and every so often the disc will stop playing and it will continue making noise. usually turning the player off and back on again solves this, but I was hoping there was a permanent solution. it is equipped with the Symphony II, sound is great but this problem is frustrating. please share your thoughts!
