BTW. I don't think the oil-change-drip suggestion is very likely - as opposed to my last car (a '91 Accord EX in which the filter was located DIRECTLY OVER THE EXHAUST PIPE!), at least the V6 filter and drain plug are NOT in a position where I'd suspect a spill would get to the hot exhaust system.
Oil dripped onto any part of the engine where the temperature rises is suspectible to producing the burning oil smell. While it may not be as noxious, the odor will certainly be much more noticeable than if it was sitting at room temperature. The typical place for the oil to drip when doing a 1.8T oil change, is next to impossible to totally clean up.
