I cannot open your attached images.

My guess.... IKE and EWS checksum.

Re-inspect cluster connection .

Andrew, It is a v8-I have looked inside ECM/box in engine compartment and I don't see any fuses. Are you referring to early cars, say pre 2003? Or am I just not seeing what you are referring to? This issue is driving me crazy as to what could be problem. I continue to research solutions, checking wiring/fuses, etc. My next step is to try my OBD cable on my E39 or my other E53 and make sure I can access the DME on those to verify the cable is fine. The work goes on....

The one I worked on was 04. There is a little power supply unit in the e box when that fails causes all sorts of hell.

I think it might be called the IVM integrated voltage module
