hi all, just starting with this stuff, i've read alot of this thread but not all so please forgive me if this has been addressed before. though now i'm afraid i got the wrong cable i my cable is clear, not black in color. i got it from a seller in canada, it was linked at this website http://www.e90post.com/forums/showthread.php?t=480261
under the cable to purchase. that link is now dead for some reason, i just bought this a couple weeks back. this is the cable and seller http://cgi.ebay.com/ebaymotors/ws/eB...m=220824037679
anyway on to the issue, i followed the setup on the first few pages. inpa works somewhat, i can few the engine live data and stuff, though thats the only module that works, the airbag test fails. ncs fails every time with a coapi-2020 error. any ideas? depsite that i'm afraid i'll have to buy another cable. thanks oh car is a 2003 M3, so little older then most in this thread. may have something to do with it?
