Summary

"VANOS Faults Stored in DME (Bosch). The Service Engine Soon (MIL) is on 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. Due to unfavorable Engine Position Management (EPM) parameters in the DME software, various VANOS control faults could be set. These control faults relate to implausible camshaft position (intake or exhaust), the camshaft stuck situation, or the camshaft angle offset to crankshaft outside the tolerance range."
