Looks like you nailed it Phil325i. The connectors are for two absent DISA valve motors that would be there if this engine had a three stage intake manifold.
I found a nice description of how they work here

I guess it's better than just leaving the wires hanging or um deleting them but why design a special clip just to display the useless things right on top of the engine? I'm still wondering if since the wires carry a direct ECU signal they might have some diagnostic value.

I've got to mention, other than BMW's peculiar choice of things to leave out of this car I really love driving it. Coming from an E46 325ci I find it to be considerably quicker especially accelerating from mid to upper RPM ranges. It has surprised me a few times with unexpected available power yes even for a 328i. Lots of fun - just like a BMW should be!
