Well, Code 2387 is the turbo actuator motor not responding-mechnically.
With that being said, it a problem with carbon build-up inside the turbo or bent fins?
Or, is it an electrical problem with the turbo actuator module, or maybe a specific sensor, that receives the commands (for greater air) from the Engine Control Unit?
I would insist the shop check the turbo actuator first before before they remove and dismantle the turbo.
