What causes Scania DTC 617?

The cylinder gives different power than the other cylinders. This may be due to internal or external leakage in the injector, or defect control valve. Low compression may also lead to this DTC. The DTC can also arise due to air in the fuel system, caused for example by low fuel level or leakages in the supply circuit. In this case, probably more than one cylinder will be detected as defect.
