Although the latter is eminently acceptable, I seem to recall that the M850’s may be programmed to start up with both valves open initially. Should that be the case, replacing the fuse will not solve my Talladega mornings dilemma. Any advice (aside from trading for a Prius) would be appreciated.

If it’s like the 550, you’re right. It starts up with both valves open. These cars have loud cold starts. But it only lasts 30-60 seconds. It’s like a crying baby - it’s louder for you than anyone else because you’re self conscious about. The neighbors will get used to it.
