Klaus,

Put in a new filler cap seal. Lifted the car and looked beneath the plastic housing at the filter. The tech didn't get the thing screwed on right and it was weeping. As you know, on the newer V70s, there is no metal housing for the filter, but rather, you put in a new filter and reuse the metal reservoir. Anyway, got a new seal/o-ring put on it as well, so we'll see. No evidence of leaks elsewhere. Gotta love sloppy work.
