I have a 2007 S80 and had the oil changed then smelled like hot burning oil...took back to dealership where they cleaned the engine all off and said there was a small hole in the breather box...anyone have this problem before?

 

A sloppy fill job by the tech can end up with oil on the exhaust manifold or other engine parts that get hot enough to burn the oil causing the bad smell. Nothing to do but wait for it to completely burn of and the smell to stop. Shouldn't take more than a couple of days.
