That's an exciting question, both technically and legally. I'm surprised that it was even possible to rewrite the ECUs in BMW cars.
If we think back to the Ford engines in the Roadster S2 and 3.7 with the ugly revhang, absolutely nothing could be rewritten from the outset. Ok, that's a different situation than when something suddenly becomes impossible at BMW during the ongoing process that was previously possible.
