http://www.alldata.tsb.com Has anyone tried this service or the cd roms? They offer Just for your vehicle "Shop Manuals" and Just for your Vehicle "Technical Service Bulletins" Are they worth the money? Also I am still looking for a straight answer to the correct oil filter for an 87 5000 cs Turbo Quattro. lets have a vote....Mahle oc47 or Mahle oc85
