Hello,a good thing to do that may benefit you down the road with alot more things with your Beamer is like i did we just got our daughter a 91 Camaro i went to a auto parts store and bought a repair Manuel that shows you how to do everything even tear down an engine and how to rebuild it too,so these books are really handy to buy in case you run into other problems /Questions you'll have immediate access to all your answers you can pull out your book,i think i only paid about $20.00 for the book but worth at least 100 times that.Jim
