How to: Realign the CAS and the DME - BimmerFest BMW Forum The majority of your Fault Codes indicate that "No Message" was received by the EKPS, DSC, or VGSG/VTG from the DME. Those other Modules are operating fine; its the DME (Transmitting/ Sending Module) that is at issue.

For there to be "Communication" with a particular Module, such as the DME, TWO things are needed: 1) Power Supply to the Module (keep that thought ;-) 2) Bus Communication ... 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 ... DME verifies all incoming data by comparing it with the reaction of the rest of the system.

If a defective sensor delivers unrealistic data, DME replaces this with preset standard values. If a spark plug fails, DME immediately cuts fuel flow to this cylinder in order to prevent engine damage.
