Ask another BMW clutch-equipped car owner to test it out themselves, may be normal. By way of reference, I own a Corolla 10years older than your BMW, developed a sort of similar symptom one time. Turned out to be caused by a combo of a faulty (mis-adjusted) throttle position sensor and faulty idle air control gadget.
