Yes. I've used that before. I was eventually able to find what I was looking for (AC Freon weight for system fill). It isn't too bad, but doesn't seem to be all inclusive like a typical FSM, seems to be missing sections on certain ones.Yes, some cars are easy to find, many, like VW TDIs never seen. Some libraries carry them.
I actually came across something recently, not real great, heavy with ads, worth a look.

ctrl + F in a PDF FSM is about 10000x easier than searching these forums for a "how to". plus, an offline copy would be fantastic.Most of what you need to work on is probably in a DIY somewhere on this site. Do a search.
