My cable is essentially a K cable, pins 7/8 are jumpered, and it does 'read' the info from the E53, but with Rheingold I can't program with this cable. So I think I need an ICOM cable or something else. Hoping someone with Rheingold and E53 experience can give me some input?

It doesn't sound like you need to code anything (just yet) but some basic diagnostics is going to be a good start. Are there any significant codes showing when you query the DME?
Have you pulled the DME and relays back out of the e-box and checked connectors etc.? There are no coincidences when working on cars like this....
