So the noise comes from the valvetronic system. I bought a Foxwell NT510 and it showed a valvetronic error. The NT510 has a valvetronic "learning" function. Ran the test and the noise immediately went away. Its possible it might rear its ugly head again but at least I know what it is. The NT510 has already paid for itself.
