Could be a bad DME, bad wiring, missing supply or ground The answer below the codes states that the valvetronic motor killed the DME output but I don't think that's the case since there is another message stating that the position sensor isn't readable, which is not related to the motor issue Plus the DME outputs are well protected Also no message from instrument cluster is interesting

- e39 DME replacement!! HELP!! | BimmerFest BMW Forum
The DME is the top (closest to the firewall) module I believe Unplug the harnesses and presto, your DME is free Your EWS is located underneath your steering wheel on the left hand side You'll need to take off your lower dash piece to gain access if I remember correctly It's held on with two screws
