Updating this thread to note the additional steps I took and ultimately how it was resolved for me.
Installing the replacement rain/light sensor did not resolve the issue.
I then scheduled time at my local MB dealership to perform another service, and requested they program the rain/light sensor in the replacement OCP. They were unable to program it... even though they still charged me for labor.
I then searched eBay until I found an OCP that had the rain/light sensor cable still connected and ordered it.
Upon installation the rain/light sensor began working again.

Two choices have someone with Xentry (MB diagnostics) clear stored codes, pull new, and attempt reset or swap out the sensor with a used one from ebay cheap enough and normally free returns if this is not your problem. Provide VIN if you need part #.

Follow suggestions from @konigstiger , if that fails, and you are willing to pull out the OCP see
Here is sample from Ebay, https://www.ebay.com/itm/27476914032...3ABFBMnPfHh7ph

mixed signals
Hello. 2005 E500 4matic. I've no cable between rain/light sensor and overhead control. Searching for a replacement provides mixed messages. Most suggest this: https://www.ebay.com/itm/122800836797
Both ends do not fit. No-go.
This looks more fitting as the thicker proximal cable end is chunkier and square: https://www.ebay.com.au/itm/266433386546.
Same setup as this video, thx konigstiger:
The part isn't readily available in US which I find odd. Any US part supply sources you could provide would be most helpful. Happy holidays.

Also, the rain sensor itself shows up in the EPC under front lights (with the exterior headlamps), and not under the Electrical System/OCP section.
Sorry I have not seen the wiring listed yet

Yes to your confusion. That AU part is right though considering the ubiquity of the W211 here in US why is the cable only available 10000 miles away ATM?
It is odd that this cable isn't available closer...that was my confusion. Asking around US Ebay sensor dealers brings no luck. They have the selfsame sensor offered here in the US though no one has the corresponding cable.
Now that's odd.
Where'd those cables go?
Anyhow, I've a pipedream of finding the cable in a close-by pick and pull. There is a junkyard nearby that had rotating stock of domestic and Asian cars and I frequent it for this and that. European auto graveyards aren't as frequent 'round here.
Any suggestions are helpful and thank you for all you've offered so far too.

Ordered and installed another cable though had to snip off extra plastic and sand down rough edges for both ends to fit 3-prong receptacles on OCP and sensor.
9091 Communication fault with component B38/2 (Rain/light sensor) changed to rain-light sensor no echo error code. Something changed. Advice? Thanks ahead of time.
