2006 Audi TT Special Edition? Is clicking when driving straight, but slowly. Has a clicking noise. Was suggested was my strut bushing? Does that seem correct? And how to upgrade stereo, phone calls over car speakers? without using bulky fm transmitter? And car has no iPod dock, no audio cord plug in? Why so little in what’s called Specia edition? Non electric seats, non heated seats? Crappy single disk cd player and no audio plus in ? No usb charging? URG!
