About two years ago I got the P13B6 code, using a generic code reader. I was also not able to learn much about it. I replaced all my ignition coils, and the problem didn't return for a while, so I thought I fixed it. However, recently the check engine light starting going off again. Fortunately, in the interim I had spent some time getting DIS set up on my laptop, and I purchased a D+KCAN cable. So now I can do real diagnostics on my car (the wife's 2007 X3, to be specific).
Here's the details on what the P13B6 code actually means. However keep in mind I don't know whether P13B6 is a generic code for several different BMW-specific codes (for example, maybe P13B6 shows up for both intake an exhaust camshaft sensor problems)

I found some good information on the 2A99 (P13B6) code here:
Fault Code 2A99
Hope this helps those that don't have DIS.
