Starting to sound like an EMM problem to me or other electrical issue affecting the starter and oil pump, strange that an engine working fine before a service then has issues first time it used after, bad software update :?: . Sitting for 20 months after wintering should not be causing the issues you are seeing, which is why I asked about the service source.

And if it is the EMM you certainly can break things :idea: .

Kadet:
Quite possible. That's precisely my point. If all the subsystem are monitored and regulated by a proprietary computer (which, by the way, comes at around $1,500) then repairing it or even debugging it is a major, specialized project.
But then again, maybe updating the software is what it takes. Keeping my fingers crossed
