Valvestronic sensor in the BMW 3 E90 is responsible for regulating the opening height of the inlet valves, thus performing the throttle function. When an error occurs in this sensor, this means that either the sensor itself or the servo motor-more accurate information can be obtained by running the engine diagnostics.
Fuel quality and the relative fragility of the servo motor motor can be described as possible causes. Only the replacement of the part can help in this situation.
