What are the effects of a faulty turbocharger solenoid valve on a BMW X6?

[MacDallas]

If the turbocharger solenoid valve of a BMW X6 is damaged, it can lead to poor sealing of the turbocharger impeller shaft, severe blockage in the exhaust gas recirculation pipe, and significant wear on components such as piston rings, cylinder walls, and valve oil seals. Relevant information about turbochargers is as follows: 1. A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbine chamber, which in turn drives a coaxial impeller. The impeller then pressurizes air delivered through the air filter pipe, forcing it into the cylinders. 2. The function of the turbocharger solenoid valve is to overcome spring pressure and separate exhaust gas flow. In a turbocharger system with an exhaust bypass valve, the solenoid valve controls the opening time of atmospheric pressure based on instructions from the engine control unit (ECU). It generates control pressure acting on the pressure tank according to boost pressure and atmospheric pressure.
