Sorry, getting the hang of this. I saw in the forum about a month ago people talking about their A4's when in traffic, the EPC warning light coming on with a siudden loss of power, I guess car going to "limp home mode". I have the same experience with my 2001 A4. I took it to the dealer who clenaed the throttle body. It didn't work, it hapopened again yesterday in traffic. Does anyone have any similar experience/advice?
