I have an 88 735iL. Can anyone help with a comprehensive list of the hidden OBC codes? I saw a reference once to checking alternator output voltage using the OBC and I'm sure there are a bunch of others. Also I know you can change the "fireup" order of the OBC. Can/will someone point me in the right direction, possibly an older post?
Thanks

Make a folder in your favorites with all the web sites you find for your BMW. This way, you built an information database of "knowledge" you can refer to...









...how do you think I started? :D
