Your symptoms might be an indicator of low refrigerant charge, I recommend testing the low and high side pressures, the ambient conditions (temperature and humidity) and comparing them to the charted or goal numbers BMW publishes. If you need me to, I can get those figures for you.

If the refrigerant charge was low would it not blow warm air on both sides of the vents. All my vents on the driver side be it feet/facial/windshield blows out cool air condition. All vents on the passenger side blows warm air.

You have made a point. It does seem logical. However, the air conditioning will blow cold air from the drivers side and warm from the passenger side if the charge is low. Do you know the high and low pressures? If you have these numbers we can develop a diagnostic procedure, even if it is to eliminate one factor in the equation. Are you with me?
