Guys, don't laugh... In pursuit of chasing down my error code 66 issues, I gave the BBOD hoses and solenoids a clean out with carb cleaner...after which I forgot to plug back in the big connector that provides power to all the little solenoids in the box before going for a drive...anyway, found that, sorted, cleared the codes and carried on. Well, she's got no boost on the primary. I am getting boost high up in the rev range. No error codes. I checked and quadruple checked the BBOD hoses and electrical connections and haven't spotted anything missing. Plugged the greens together to cycle the solenoids and I can see the one that hose number one plugs into doesn't appear to be working. Line one goes to the intercooler control valve (IACV), which, if I'm not mistaken, should always be under vacuum (and in the closed position) until the secondary kicks in, at which point it moves to atmospheric and opens. There is definitely vacuum (from the tank in the RH guard) sucking that solenoid, but at no point does the other side of the solenoid go into vacuum. If I remove hose one from the solenoid and give it a suck, the IACV closes, so no blockages along that path. I've yet to check to see if power is getting to that solenoid. Is that a removable plug on top of it, or is it permanently hard wired? Doesn't look like it wants to unplug. Do these solenoids die sometimes, or are they rock solid? In the interim, would it be safe to bypass that solenoid to get vacuum to the IACV, provided I keep it under 4000RPM sort of thing? I've got to do a big drive in the weekend and would rather have the pre VOD range available, if I can't get it properly fixed in time... Thanks in advance for any help/suggestions...apart from the "go single turbo" ones of course ;-)
