Just to be clear, there are two different noises being discussed here... there is a resonance/raspy noise which is normal and nothing to worry about, then there is a noise from the DI pump which might be something to worry about, or it might not.

The only way to tell for sure which noise you're hearing is to log the DI pressure and look for a consistent wave.

Now that logging is working for me again, I'm going to pull a log to see what's happening with mine. I have an early build date (delivered July 2012) and am on the original DI pump revision, but mine doesn't seem to make the bad noise at all.
