is very hard to pinpoint your problem. it could be a combination of things. maf, vaccum leak, vanos, ccv, icv, it can also be your camshaft sensors (exhaust or intake). you should have your scanned by a bmw reader, so it can check all of the modules of the car. search the forums there are quiet a few threads with the same problem..

Have u checked ur intake manifold actuator? pull it out and check if the flap is broken... if it is then ur probably gonna have to buy a new one...
