Went to change the fluid/filter in my 603 power steering, got it all done, and noticed a little problem. In the "E Class Owners Bible" instructions, it pictures a white spacer piece with a "fill level guide" on it (according to temps). Well, after I emptied the old fluid out of mine, I noticed my white spacer bar has NO fill level guides on it! There are just sort of triangular patterns down the side. Now I have an empty resevoir with no idea how much to put in there ... help?
