The 2016-2018 items number 3, 4 and 5 have all been replaced with a single HCM module on the 2019+

Have you had any further luck?
I have a 2017 XC90 with bendy LEDs and the 4-module headlights.
Apparently one of the locating nubs is broken off and allowing massive moisture ingress. Now the low/high beam no longer work and the car is throwing a Low Beam Malfunction error, and a Headlight System Malfunction error as soon as the low beams come on.
Where new headlights are $3k + modules & coding, I am absolutely not buying anything new, and the plethora of part numbers on ebay, none of which match the online Volvo IPC or superseded part numbers really makes me weary.
The newer 2-module lights are more plentiful used, but I assumed they weren't interchangeable.
The connector is the same, but the populated pin count and locations are different, with at least one pin not common between the two.
The easiest way, there should be part number on your current headlights. Search the EBAY with that part number. You can replace the same HW while using your own controllers. You might need to manually adjust the aiming because those id*ts mess around with manual alignment screws! In general, you can replace your headlights with a different part number computable with your VIN and reload your current HCMs by using VIDA. VIDA does not know if the headlights assembly are used or not! It only cares about the controllers and modified config in CEM.
