every manual tranny bmw i've ever driven has this pulsation through the clutch pedal. it has to be runout of the pressure plate and or the whole assembly. this is the same principal as brake pedal pulsation, the runout of the rotor pushes the piston which moves the fluid through the system and is felt at the pedal.
the noise however is definitely not normal, i'd get under there and for the hell of it check the slave cyl. make sure its bolted tight to the bellhousing.
