Summary

"VANOS Control Faults Stored Due To DME Error. The Service Engine Soon (MIL) lamp is illuminated, and the engine could go into a reduced power mode with the ""Drivetrain Malfunction"" message displayed. One or more of the VANOS faults listed in the attachment are stored in the DME, although the engine is mechanically sound and no unusual noises can be heard from the VANOS area. These control faults relate to implausible camshaft position (intake or exhaust), to the camshaft being stuck situation, or to the camshaft angle offset being outside the tolerance range. Due to unfavorable Engine Position Management (EPM) parameters in the DME software, various VANOS control faults could be set."
