Well Im glad this debate went on as long as it did, now I know I wasnt wrong for feeling unclear as to which one was what. I have a 2013 and the manual does not show anything for the (RED) circled cap. I just happened to think from experience of working with BMW's that it was a coolant cap and knowing that it wasnt any one of the other fluids the car took.
