Your theory is plausible, but I find it unlikely. Just my opinion.
They get the "code" from BMW and work their own as well as developing their own solutions for the power and how they obtain it. They have a state of the art engine development center and test the snot out of these things all over the place/ BMW facilities and leased rights elsewhere. They truly build these things rock solid.
