Ha -- I'm that see through, huh? Guess I didn't realize there were Volvo guys here, and moreover that they'd know who I am. The world proves small sometimes. Like I mentioned before, I mostly lurk and soak in as much as I can until I'm able to put forth positive contribution to a conversation. Glad to be here!
I've seen a couple with really odd issues like that. Starting to see issues with the CEM (central electronic module) units in these cars and it can cause a lot of really weird stuff to go haywire. Most recently dealing with an '04 V70R with over 200K miles where the module took a dump and it would just randomly freak out. Dash went dim, auto trans slammed out of gear into neutral and the whole car would go into limp mode until you shut it down, did a hard reset (disconnect battery wires and touch the cables together) and let it cool a little. Then it'd be perfect for a while and then bam, same thing. The CEM lives in the driver side footwell on top, and issues tend to correlate with heat -- as in module is dying already and interior heater or ambient heat causes it to flip out. Thankfully there is a great electronics outfit in Canada that rebuilds them instead of having to cough up the dealer price for new.
Out of curiosity, how many miles were on your R? Would the issues manifest more based on any certain condition like temperature?
