You will definitely lose bus comms when you upgrade the comfort firmware by ucm programming cable
Once it is plugged in the comfort is in boot mode and cannot communicate on the bus.
The ucm is now controlling it
Go ahead and do the firmware upgrade

Good job you don't have a patent on that as I'd owe you millions!
