Hello

I'd first check all the high pressure hoses post turbo/s for any split hoses or cracked metal pipes, also check the ends of the intercooler as its not unheard of to pop the end caps off under high boost.

a burst or loose pipe will result in over fuelling and smoke as you describe

If this Ok then it could be a major engine sensor such as the airflow meter or cam position sensor has failed so that the ECU is now overfuelling or injecting at the wrong point and resulting in poor combustion.
The quickest route to repair is to have the car plugged into a diagnostic machine which will read off the fault code stored in the ECU and indicate which sensor has failed or whether the fault is more serious.

its also possibly burning coolant ( resulting in steam) which will also produce white smoke

if its using coolant then this is backs this up
