The first step in diagnosing a problem is to scan the engine computer (DME in BMWspeak) for codes. The Service Engine Soon light is on only when an emissions related code is present.

You have vacuum leaks. Have the intake manifold professionally smoke tested. Fix the leaks. Then clear the codes and see what comes back.
