Yes! there is a data recorder I understand within the ECU, how much and what type of data it holds I do not know! but BMW dealers can interrogate it if they wish. I am aware that on the M series 3/5/6 models data is recorded, for example they only warrant the clutch provided the driver has not used launch control more than 5 times in the life of the car or between clutch changes !!!!! They know what speeds have been done, engine rev ranges etc etc. I have also heard they read the key when you go in for a service, whether this is the same data not sure!!!!

Always said I would go back to a 6 series
