Wow!  Super write up on this Dennis.  Thanks.  I meant Idle control valve,
sorry.
It is buzzing even if I take the key out.  No wonder the battery goes down.
Strange.  I can't even start to think where the fault maybe.
Maybe the ignition switch?

Waterboxers don’t have a cold start valve. That buzzing thing in the center
of the idle is the idle control valve. It is an engineered add on to
compensate for O2 sensor mixture changes, warm up fast idle, and varying
loads. The controller is located in front of the passenger side tail light.
It shares the temp 2 sensor with the ECU for warm up idle and it also has
inputs for power steering pressure and the AC compressor. It get power when
the ignition switch is turned on.

That thing in the middle of the engine, I think it’s called the Cold start
valve, is still buzzing, running after I switched the car off and pulled the
key out.  Something is going on, because it also won’t start now.  I hope, I
don’t have something strange.
Anyone?
