So I just got off the phone with the shop manager at my local dealership. He told me that as far as he knows that the only way to reset the trans. is by computer. He also told me that BMW has many different things that work that even the shop managers do not know of. He said that it wouldn't surprise him if it did work. He also told me that from year to year car computer systems are just a bit different and that it may work on some cars and not on others. Keeping this in mind, I am due for some highway time so I will know in a few hours if it did change anything at all.
