If the check engine light comes on in the instrument cluster and the engine does not perform well, meaning you do not feel the boost, there may be an issue with the operation or control of the turbocharger. Perform a fault memory check using diagnostic equipment: the detected fault relates to an anomaly regarding the pressure measured by the MAP sensor on the intake manifold.

This could be due to a dirty sensor, a faulty sensor, a stuck closed variable geometry turbo, or a malfunctioning vacuum circuit. Check these elements.
