This is just a guide to help clarify how to program BMW E chassis vehicles. Despite the E Chassis designation going back to very early on, this mainly applies to E65, E60, E70, E90, E63, E71... The older E46,E83,E85,E39,E38 chassis you might only be able to do some coding, those are set up differently with the bus systems and I haven't had much good luck with those
