Car has intermittent electrical issues, have been occurring sporadically over entire lifetime of car. Upgraded DIM and CEM software. Want to replace CEM (under emission warranty) but dealer won't unless there is an emission-relation error code. Dealer suggested replacing DIM for $1800. Check out the codes below and let me know what you think.

Those internal fault codes for the CEM would make me suspicious of the CEM. What are the symptoms?

Restarting the car usually (though not always) fixes all symptoms except for "SRS Airbag Service Urgent" which needs to be reset by the dealer. When it doesn't fix all the symptoms, the dealer does a "hard reboot" (not sure what that is). But none of this solves the underlying problem, the next flare of symptoms can be a couple hours away or several months away. Although the severity of each episode can vary and not all symptoms may occur with every episode, it just makes for an unreliable car.

The full list of symptoms in order of frequency (high to low) is as follows:
Trip odometer reset
Dashboard dies (all gauges and lights)
"SRS Airbag Service Urgent" message
Electronics die (turn signals, A/C, radio, power windows, power locks, power seats)
Headlights clicking
"Brake Failure - Stop Safely" message
Time reset
Loud thud sound (as if ABS is malfunctioning)
Engine stalls
Transmission stuck in third gear (slow acceleration, engine overheats)

Someone told me that since there are both high speed and low speed communication errors, the CEM must be at fault since these two never interact and are only processed at the CEM. If you agree, do you have a suggestion as to how I could get Volvo to replace the CEM under the following warranty?

I've not worked on these cars for a few years so I'm a little rusty, but I remember seeing issues with the ABS and CEM modules, and you could have a communication bus error. These problems are hard o diagnose and understandably they don't want to start paying for parts that may not fix the issue, but you need to stay on them and be persistent to get them to address this. I suggest contacting the Dealer General manager and Owner, Volvo Customer support and make sure the Dealer is in communication with the Volvo Field Engineer that is supposed to help address these type of issues.
Good Luck!
