Hi everyone I've got an a4 2.6 v6 quattro it's recently had two new cats and my mpg is averaging about 19 mpg I know it's a v6 but that's ridiculous, I don't speed much as I live in a little town but also have juddering when accelerating, similar to s4_dans post really but my mpg is really crap, for instance if I put say £15 fuel in it lasts about 25-30 miles please help as it's getting exspensive,
