I've read that the cylinder number that a scanner displays may not follow the diagram posted. Something about how a scanner numbers the cylinders in firing order rather than the way the manual does. This may be completely wrong...it maybe be a fault of the scanner's compatibility with BMW. Not sure...just asking...

I haven't had this issue before with other vehicles, but I am having an issue diagnosing a cylinder misfire and thought that this may be the cause (maybe I replaced the wrong plug/coil)
