The P1512 code on a 2005 BMW X3 indicates a problem with the intake manifold runner control system. This typically relates to the variable intake manifold's functionality, which optimizes engine performance by adjusting airflow. The code can trigger due to a malfunctioning actuator, a vacuum leak, or wiring issues. It's advisable to diagnose and address the underlying issue to prevent potential engine performance problems.
