I hear pretty normal injector clatter. In the first video I did hear what sounded like one injector acting up - but that would throw a soft code in the DME, so have your dealer check it out. These cars (for those who didn't know) have direct injection which means they have large, loud injectors that shoot gas directly into the cylinder, bypassing the intake manifold. Diesel cars use similar type of fuel delivery, so that's why there are some similarities in noise and why BMW put those large, thick sound dampeners on top of the motor.
