Low RPM engine whine

So I have a 2013 C350. At low RPM's, say driving through stop and go traffic I hear a whine in the cabin. It sort of sounds like power steering whine but happens in a straight line or when in neutral and gently revving the motor. In the latter case the whine increases with the revs.

I thought I remembered a thread where Glyn said this might be the torque converter, and may be normal? Either way I always hear it, though it's not deafening. i thought I'd run it by the community before my next service at the dealer, any insight is appreciated.

It's normal. It is the Transmission oil pump.
