When the check engine light comes ON this means the management system has found a malfunction with in the engine system.

Your mechanic needs to check for malfunction codes so you know what has malfunctioned.

Could be any thing from 100's of sensors on the engine ,or even a turbo malfunction code which was worked on.

this will put you into limp mode which is power loss.

If the tech / mechanic does not have the scan tool then you will have to see the dealer .
