Hello I'm new to Audi world. so I'm going to purchase my first audi. its 2008 audi a4 convertible. THE TOP DOES NOT GO P OR DOWN WITH THE SWITCH. I CAN OPEN IT MANUALLY. SO WHEN THE TOP IS OPEN OR CLOSED. I GET A ALERT SAYIING THE TOP IS OPEN. BUT THE TOP DOES NOT OPEN AT ALL WITH SWITCH. THE MOTOR DOES NOT COME ON AND MAKE ANY NOISE EITHER.. ANY SUGGESTION ??
