I did few weeks ago a mesure of the engine power on a power dynamic bench.
and the result was:
347 cv at wheels for 8000 tr/min with lid open but only
306 cv with it closed!
Lid didnt't open because of a defaillant sensor of the temperature gearbox.

Maybe engine was also in security mode!
After repair the lid opened correctly to has today.
Doubtless the defect stayed in memory and affects has new the functioning.
I have to check connectors and return to bmw to make a control to erase défaults.
