Hello, so after taking it to Atila BMW Master Tech. At Vanos Motorsports in Carlstadt this what was found. He plugged it into the scanner, 2 codes for water pump, operating under threshold and or obstruction so yeah the water pump is dead. He will replace thermostat and waterpump, do coolant flush and new oil change plus code the tailgate to close from keyfob and inside button all for $1200.

He did the co2 test came back negative, compression was fine. He asked me if I had added oil recently I said yes Castrol Edge Synthetic. He said ok thats your reason for the white oil viscosity most likely the car had Mobil in it and when Mobil and Castrol mix you get that oil foam.
