Well why would it be running if there are no leaks? You get a single shot of air on takeoff, pressure in the system drops from 19 to 11 psi (per Lexman8), pump takes, say, a minute to pump it back to 19- and it shuts off. And I assume it should stay off, so long I'm not stabbing it on a traffic light (my understanding the system is only kicking in for acceleration from standstill..)
@scw: I have also seen pics of a blown hose (armored rubber part - not the alu joint..) so clearly the whole assembly is not fit for purpose.. And they seem to be replacing it with a same part..
It's quite embarrassing that something that was announced as a revolutionary innovation in turbodiesel technology- has become a synonymous for failure.. And by having discontinued it after 2-3 yrs Volvo has admitted the failure.
