White smoke coming from exhaust

When cold starting car, blue smoke comes out of exhaust

Whilst driving my 2009 1.9 TDi Jetta suddenly lost power and then died. It starts but dies almost immediately. There is smoke coming from behind the turbo. There is no exhaust gasses coming out of the back at the exhaust. If I disconnect the airflow hose to the intercooler the engine runs.
If i disconnect the air to the intercooler the engine still runs.
Whilst doing either one of the above and i disconnect the air intake from the air filter their is exhaust smoke coming from out ( so it is blowing air instead of sucking.
