This is my first diesel and I just got my first check engine light with the error code listed above. Said exhaust pressure low, VG Turbo fault and gasket failure. The dealership performed VG turbo clean and replaced the failed gasket and the system passed. Basically what they told me was it was from putting around but I haul a landscape trailer or ski boat lots of the time but I do go back and forth on some short errands. What can I do besides changing how I drive to fix this. The truck still has warranty and I spoke with the service manager who was pretty cool about overlooking a few mods. What mod or upgrade could I do to prevent this from happening?????
