It would appear that there is a crack in the exhaust manifold or a faulty manifold gasket. The fault light may be the ECM warning of a "faulty" O2 sensor which is the one after the cat converter as the ECM reads the differences in voltages between the front sensor ( HO2S) and the O2 sensor.

To turn off HDC on a BMW, all you have to do is press the HDC button located on the center console.

If you ever want to turn the system on again, just press the button again.

6 years different and a different series? If only life was that easy! Some BMW have a mechanical pump driven by the serpentine belt, and some have an totally electric powered pump.
