Hi, welcome to Just answer! My name is Ross and i will help with your question

techmachine :

It sounds like you have an air leak on one of your intake pipes or intercooler.

The turbocharger pushes pressurised air through these pipes, if the air is leaking the pressure will drop, the lack of air being delivered to the engine will cause the engine to over fuel, this causes the black smoke.
