Vcds . Block 032. Both fuel trims are on 0. Recently had everything unplugged doing jobs... got it all back together... drove it around the estate and noticed boost gauge is now sitting at 0 at idle!? And when i rev a tad it goes up! Doesnt make sense... cars running very rich.. sounds like external wastegate is leaking every so often at idle! Checked seal and its fine. - no fault codes on vagcom - no boost leaks - no vaccum leaks that i can find. - inspected dump valve seems fine. - inspectes FPR. Seem fine left car running with block 32 on ...and still sitting at 0 fuel trims 5 minutes later! Whats going on!?? Help! Cannot figure this out at all!!
