Hi there, I've got a guy with a intermitent boost fault "code 17965 charge pressure control intermittent" and he has this black box which I've put a white dot on, it's up at the left hand side of the pic at the rear. The car is a 2009 tdi and we're wondering what this box is and what it does as he doesn't have the regular N75 on the bulkhead, instead all the vac lines go to this box.



Any help on this would be great, thanks:)

more pics of the box would help but I'm guessing it's a beauty cover for something else like a relay box or some solenoids. His N75 could be under the windshield. I see some soundproofing along the firewall, it shouldn't be behind that.

No all the vacuum pipes go to that box but I'll ask the guy for a better close up pic or even better get him to join the forum and post them himself:D
