Hi .

The code P0299 .Low boost abnormality diagnosis

Possible cause for this code .

  1. Faulty turbo or supercharger
  2. Low oil pressure in the engine
  3. Fault in the EGR system
  4. Air or intake leak or restriction
  5. Faulty boost pressure sensor

Most common is intake leaks .vacuum low and then bad Turbo .

Check the vacuum to the turbo actuator .

Check turbo boost with a gauge this will confirm map sensor readings .

Check the actuator with a vacuum pump .if does not move check actuator or turbo could be sized .
