There is this noise that comes through the driver side dash/vents during the Cold start (RPM revving up). It sounds like liquid circulating or leaf blowing inside the vent. The sound goes away after the engine warms up.

Anyone know what this is? Is this TSB: Noise From Bank 2 Vvel Actuator or TAPPING NOISE FROM DASH AREA?

Thanks

 

that TSB is for a ticking noise that occurs at ALL engine temperatures.

The engine does sound different when it is in open loop operation during warm up. That is what you're hearing. It's much more evident on the coupe since the exhaust note is drastically different during warmup.
