I googled and started a thread and someone said it might be a cam sensor. I plug in INPA and it flat out told me I need a new cam sensor.
If the op would have had the code read via some sort of BMW software, this thread would have never been started, and he would have more money in his pocket!

It does not quite work the way you think it does. OBDII supports cam sensor error codes as well as many other. Regardless of what tool/software is used, there is rarely any clear cut thing that says "replace this part and your problem will be solved". All any code is a "clue", there was some logic statement that something was outside of a parameter threshold to allow the code/error to trigger. The is no specific magic about any tool whether a generic OBDII App or a $50k dealer tool. At the end of the day, ALL information needs to considered and it will be an educated guess/decision as to what the next step may be.
The M54 is a vacuum leak waiting to happen and if I had to guess the OP has one or more vacuum leaks on his 13-14 year old vehicle.
As I mentioned it will be highly unlikely that the OP actually has a Rich condition, most Rich conditions, if they exist are false positives.
