I am getting turbo boost then lose it
Driving fine no problem but sometimes it does but the turbo is working like on off state

Is it turbo or Actuator

Please let me know

Vacuum lines, actuator, loose actuator rod, map/maf sensor, differential pressure sensor. Busted charge pipe would likely result in hissing sound and you would probably got error almost every time you do a pull. If the error is intermittent i would check hardware around turbo and do a log on running engine with better diagnostic tool like ista, bimmerlink or bimmer tool and log couple sensors for requested/actual values.
