All info using Multiecuscan registered V5.3

I replaced the clutch plate in all 3 vehicles so I can guarantee the km noted above.

Note battery voltage.
Vehicle 1 had been sitting for 5 weeks.
Vehicle 2 the battery was fully charged before connecting Multiecuscan.
Vehicle 3 was a brand new battery & fully charged before connecting Multiecuscan.
I think it is important to have the battery fully charged as you will run into problems doing calibrations etc as the ecu voltage in 2 of these cases are definitely not 11.9 & 11.6 volts.

I hope others find this information helpful.

I have also noticed that the Comfortmatic ECU reports lower voltages than other ECUs, at least when the engine is not running.
Below are some values for my 2018 2.3/150, CFC448. I log all Comfortmatic parameters now and then as reference values in case of future problems, and to spot any trends. The last column is highlighted because it's different i.e. the engine was running:

And also a table showing clutch positions while travelling/idle/engine off; logged at 29850 km:

Plus a graph showing the Gear/engage and Selection positions, based on values logged while driving:
