The edits as far as I can tell relate to the RDU in the video, which is the type found in my 2017 Sport, but don't believe its relative to the RDU being discussed in this thread.

@garycrist that video shows the RDU type in my 2017 and don't believe it has any bearing on this discussion. I have changed the RDU oil in mine and its regular gear oil which I don't believe will work in the RDU for the model/year Edge discussed in this thread.

For extracting fluids where there's no drain plug I use a wire coat hanger inside some clear tubing forming a shepherds hook, connected to my regular oil extractor.

Generally the differential oils contain friction modifiers which cause issues with wet clutches. Similar reason why its not good to use car engine oil in a motorcycle due to the wet clutch - motorcycle engine oil does not contain friction modifiers. Redline and Amsoil are top rated, so if they put it in writing that their oil is compatible I'd trust that. The Redline website kind-of indicates that its compatible.

How did this go? The below thread shows some detail posted by @Wubster100

Welcome. On the purge valve - I've followed a similar path, replaced the complete assembly with a 3rd party brand, replaced just the solenoid and both had a very short life - I'm on an OEM one for about 7 months with no issues.

Welcome. What work did you do on the AC and how do believe that work was related to the low oil pressure event? What rates do you charge?

Welcome. eBay is known for counterfeit spark plugs and other components. Best get Forscan and scan for codes as the starting point in your diagnostics.

This morning's commute to work in a storm made me appreciate the rain sensing wipers - the auto change from intermittent to continuous and speed adjustment based on the need worked flawlessly.

Wow, that's more work than I'd be willing to do for that feature - turning off for me using the screen would also be an issue. I most often forget to turn it off when approaching the car was and their spray triggers the wipers and I have to scramble to turn the rain sensing off. My wife's BMW X5 is smarter - it turns off when the ignition is turned off and when you need it again with the first few rain drops you tap the button on the end of the stalk.

Yes, the rain sensor needs a clear spot. I don't think it will be easy to remove the coating in this area. Look to see if you can find the yellow and black wires seen in the below photo.

Definitely need a replacement windshield to mount the rain sensor. See the rain sensor mounting in the below thread:

Don't have any suggestions other than checking for codes with Forscan.
