I am refreshing the plastic engine covers on a 2004 A4 B6 Quattro Cabriolet with the 3.0 AVK engine. I am confused as to whether that year/model actually had a right-side engine cover. While it is shown in the service manual exploded diagram together with the front, rear and left-side covers, I can find no compatible part for the 2004 model on the Audi or other parts stores. I see a 2003 compatible part, but the attachment points on that item do not match my vehicle. Does the part exist for my car?
