I'm leaning towards more of a bad turbo. Seal. Or coolant getting into exhaust.
I honestly dont know from experience but it appears white smoke is pouring excessively out one side of the exhaust which makes me think its turbo related.
White smoke meaning water.
The excessive water could trip up the o2 sensors and mixture. Have you any logs? Hows the performance of the car?
