Perhaps I'm looking at a different DIY.

My question then was, will any coolant do, or do I need special BMW coolant.
I use peak longlife. It is phosphate and silicate free. Change it every two years for the hell of it.
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
