fofoMK3, 1.6l, tdci goes into limp mode.The boost pressure gauge (MAP) shows 255kPa (maximum value) over a period of about 3 seconds.The DTC that is displayed is P 2599 (Turbocharger Boost Control Position Sensor A Performance - Stuck High), but the sensor is at an average value of approx. 2.5V and U 0418.My question: Is the borderline boost pressure to blame for the emergency operation, ie does the machine go into emergency operation because of the high boost pressure?If so, why is the DTC P2599 coming?Get an answer within 90 minutes from Europe's largest car and motor community with over 50 million posts.
