thanks for that note.

I have access to my neighbor's vacuum pump and he has a set of gages, plus the PAG oil. We've done several refills on his older (mid 80s) Benzes, though he has no scale so he refills until the pressure comes up about right.

Guess we can do the same for the C280, just need to get on schedule with it. There goes half the weekend, at least. Well the wifely unit will scream until it's done, so off I go.
