As you suspected..No joy even with disconnecting pin 8. Probably only usable on older cars. Cost of experience...$20. :-) I will keep it around as I am shopping for an 2006 E46 convertible.

I have this cable in my shopping cart:
Car Diagnostic :: By Product Type :: INPA & Ediabas :: BMW INPA / Ediabas K+DCAN USB Interface - one-stop-electronics.com

But I suspect shipping time is like 2 weeks...ugh, that is a long time! ;-) Any reputable DCAN cables available from a US seller? (As I understand it, I need the DCAN for the '11 X5)

Maybe I should just order the cable, and get to work replacing the cam in my TDI....but coding is so much more fun, and a LOT cleaner.
