A "tapping sound" From the Drivers Side of the Engine on Infiniti G37

A "tapping sound" may develop from the drivers side of the engine. The noise may be associated with the variable valve event and lift actuator. Our technicians tell us a software update for the powertrain control module (PCM) is available to correct this issue.

Yes, get that tapping also, used to be louder. Oil brand change helped but the dealer went back to Mobil. The big fear is, is there enough oil getting to certain parts or is the oil volume too small at low RPM?

I have the same tapping noise on my 2012 G37s. It's random and most definitely on the driver's side area. I truly hope the PCM (ECM) update will fix it.
