I was talking to a fellow rider last week. He was telling me that some of the new BMW bikes are having fuel sensor issues. The guys in the cooler climes aren't seeing the issue, but down south (Florida, etc.) the high heat along with the high humidity are wreaking havoc with the EFI computers, so a lot of bikes are needing to go into the shop. From what he told me, the sensor/programming that is causing the issue doesn't have a good fix yet.
Doing a quick google search turned up this thread:

So it sounds like there is a workaround. Still, you'd expect better from the BMW engineers, unless of course their goal is to keep the BMW bike shops busy...
