So I just recently got the Bavarian Technic cable/software for my 2008 BMW 328xi and it is pretty handy for checking codes and stuff but I have no idea what half of the activations and commands do. Is there a good resource that explains all of this? For example on my transmission I have the following commands available: Reset oil life counter - guessing you want to perform this after changing the trans fluid, didn't even know what this was tracked since I thought BMW said trans fluid was lifetime fill Reset all adaptation values - adaptations seem straightforward enough Teach in components - ??? EWS reset function - ???
