  The boost pressure control valve (BPC), also known as the APC
  solenoid valve, is used on most Saab engines to control the turbo
  charging pressure. The valves on Trionic5 models are often prone to
  failure. In some cases it just needs a good cleaning, but sometimes it
  becomes permanently stuck in one position, causing the car to either stay
  on base boost, or go into overboost until it hits the fuel cut. This
  article provides an insight on what could be casing these permanent faliures.
