I used my Foxwell NT510 scanner and read the GWS (Gearshift selector) but there are no codes stored. I have ISTA but haven't used it yet so need to read the guide to learn to connect. I have the BimmerGeeks cable that I purchased to get the transmission coded. I guess I'll see if I can get another shifter from the pick-a-part this Friday and test that. I'll report back once I have done this test.
