Absolutely outrageous. :mad:

Here's a solution, if you're a DIY type....

OBD Diagnostics, Inc. - OBD2 All-In-One Scan Tool w/ USB

Thanks J.
Do you have this diagnostic tool? Does it work well, and do you need any code deciphering literature to understand trouble codes? I have never used anything like this but since I have a couple of X5s, it might be a good investment. I will call the 800 number and check into it. Thanks again for the insight and advice.

$125?!?! I'm sorry, but that's f-ing stupid!! Autozone and O'Reilly's/Schucks will let you use there for free. Sure, its not the same DIS/MODIC that the BMW dealerships use, but the P code you get can at least get us in the ballpark w/ what I've seen in the past.As for your puff of smoke at startup, that's classic signs of needing the OSV valve replaced on the intake. It's a bitch to do it w/ the intake manifold installed, but it can be done. If you're going to remove the manifold, replace the valve cover gaskets and valley pan gaskets while you're in there. Hope it works out for ya.
