120408 DTC

So I’m dealing with a 102408 code that clears when I turn car off and comes back whenever it wants apparently. Throws car into limp mode and no other code present. Before this I was getting a 12B505 code for O2 sensor which I replaced both for good measure and reset adaptations cleared all codes and all was good…. For a bit. Now I just keep getting this solo code and it’s driving me nuts.

Anyone every dealt with this code or pointers on wtf is going on lol. Car is a 2016 BMW 750i with the N63R aka tu2 engine.

Thanks for any input in advance

Happy boosting
