Update: 7,400 miles since last change
Decided to change the oil again. Just trying to get whatever oil that was left behind since the last change. Well the oil came out looking NEW. Since it was only 7,400 miles from the last time I changed it, it is not that shocking. But it does confirm that the oil needs to be changed. Black oil in your transmission is not normal (which is how it looked (yellow to black) the 1st time I changed it). Still shifts smooth.

If no codes are being thrown use Chevron Techron fuel injector cleaner (concentrate). It solves rpm fluctuating upon cold start-up. Also, for most BMW problems start off by scanning your car with the Peake Research Tool. It contains the actual BMW codes. If you want to register a newly installed battery for free (just buy a $10 cable) and google/download BMWLogger
