Yes sounds like the turbo has failed . Is the engine light on?
Customer: replied 5 years ago.

no engin light its not on. no alarm in any way. also i do hear a hessing sound


Expert:  Cardoctor74 replied 5 years ago.
Ok that sound is the sound of the failed turbo internal . First make sure there are no broken vacuum lines at the turbo if there are no broken vacuum lines then the turbo is going to need to be replaced unfortunately . You can get one from a salvage yard or eBay to save a lot of money and have that installed. This is the next step for this issue and unfortunately you had all the symptoms of a failed turbo. Hoped this helped. Positive feedback and bonuses greatly appreciated . If you need any further assistance please let me know.

can you please give me more detail.

why my car was bowloing balck smoke and its stop now. is it becaouse of turboe charge?

and when you said is ignition switch issue. how will i repair it?

Expert:  Cardoctor74 replied 5 years ago.
Yes the turbo when it was failing was blowing the black smoke and when it failed that's why then stopped . As for the immobilizer message that would be from a shorted ignition switch . These are what need to be checked to fix this issue.
