The procedure is in the Mercedes WIS software. It may also be on the R230 Tech DVD.
User "television" over on the Benzworld R230 can email to you or post PDFs of the procedure. But I think you have to start a new thread on that forum to get his attention. He may also have a copy of the WIS to provide for free.

2008 R230: Does the "red battery" icon indicate that the BCM is bad? Or can the BCM need replacing whether or not the red battery icon appeared? My repair shop says I need the BCM replaced but I never saw the red battery icon. This was recommended after I couldn't start the car. They claim it had a dead battery because of a bad BCM. Typically, my experience with a weak battery has been a slow start warning. This time I had no warning, just a "single" click sound when I tried to start it. Any ideas?
