I have a 1990 760 Turbo and the check engine light is on. I would like to know how to check the code(s) and then how to clear it/them. It's a 1990 so I figure there is probably a way to check it through a blinking LED or something along those lines. Thanks in advance.

 

Try this site it tells you how to pull codes.
