Error code P1412 - anyone know what this one means?

Hi Folks - I threw a code today that I've never seen before: P1412. My cheap code reader said it didn't recognize the code and referred me to service manual. Anyone know what this is?

Specifically my code reader said: P1412 - DTC definition not found. See service manual.

Most likely a vacuum leak or a failing secondary air pump but I wouldn't trust generic P1*** codes without a corresponding bmw hex code. Any recent work done? Maybe a loose connection (hose/electrical) somewhere.

Thanks...I did replace both throttle valve actuators back in October and it's been great ever since (no codes). I did have a secondary air pump code once a loooong time ago...wonder if this latest one is related??

I cleared the code, will see if it comes back

"Secondary Air Pump/Secondary Air valve Large leak" or "Evap. Em. Control System Purge Control Valve Circuit (Bank 2)" are the BMW specific codes.
