I got a p2187 code the other day after I.. umm washed the engine bay with hose(yeah pretty stupid of me). But anyway I cant seem to figure out what it is. The cheapo scanner pulled a p2187, so im running lean. I assume its related to a vacuum hose as I get up to 10 psi my turbo makes like a woosh sound like its leaking not sure if thats normal, However I cant seem any evidence of it leaking. The only thing I have done since is perform a seafoam treatment. The cel is also only present when the car is on and idling. through the vacuum so before I jump into buying bavarian diagnostic software I am wondering if anyone has any cheap suggestions.

Sorry just realized I posted in the wrong forum.
Can someone move this to r56 problems.
