Now, neither bank will start. Perhaps the second bank is a different issue, but even if it is, one bank isn't enough to haul this vehicle around.

I cannot find a shop near me (within 100 miles) that has the capability to assess/correct this. One dealer said their factory diagnostic equipment no longer supports this vehicle. That conclusion was echoed by a respect independent BMW shop.

Is there anything to be done here, other than sell it off as a parts car?
Factory diagnostics work just fine on this car.

What do you mean one bank won't start? Have you checked the basics like fuel, spark etc? These cars aren't exactly difficult to diagnose.
