Anyhow, I did not have that part and too much air was flowing through the idle control valve. This explains the fault I was getting 2B0D of the idle control valve.
G-Power is sending me this piece from Germany today. I am glad that G-Power is finally working with me to resolve the issue.
I been working with Chris, he has been quick to respond lately. My M3 is running and so far good. I am going to test drive a little further away from home before I let G-Power know I'm satisfied with the tune. Cold starts are rougher than normal, but it feels tighter than before. I am still getting a DCS fault on my dash.
