I have a couple questions regarding my new to me 2004 A6 Quattro 3.0... First, the dome light appears to be working intermittently. For example, when I open the driver's side door, sometimes the dome light will come on and stay on, sometimes it will just flash for a second, and other times it won't come on at all. It works every time if you turn the dome light on by the button. I assume its something to do with the switch and the door, but was hoping someone may have already experienced this and knows a fix. I did a search but I couldn't find the exact same issue.

Also, I am looking for parts to fix up some of the interior trim that has paint worn off. Like the door lock switches and the heating and air control buttons. Any suggestions on where to get these?
