It is common to see the variable vanes inside the turbo seize or bind from carbon buildup. This causes an overboost or underboost condition when driving.

    The vanes on my turbo failed 3 different times. My friend who works at Garrett told me the first time it is due to the small diameter oil return line, Ford laugh at me. Then at 65,000 they told me of their great fix, I laughed after I had them bring my service records and my documented comment.
