Check Engine Light and/or Hesitation Due to Failed High Pressure Fuel Pump
2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.
