Boost leak i`d say..

More than likly a popped pipe or a split hose etc.. due to the increased boost.
 
As above proberly...

id change that d/v aswell even more so now its mapped...

my oem one the diaphram split and cost me £380 that was standard map aswell...:cry:
 
Yep hadnt had the car long was before i was a member on here

But the eml came on so took it to AMD done the vag-com thing needed new d/v so 007p maf was fooked because of it aswell needed some new vac hoses as some were perished and changed the coolent sensor aswell al the bits plus the labour = £££...
 
just changed all vac pipes found one was split took car out felt better holding boost better but lost all boost again after a while i noticed that a piece used for n249 the bit where two pipes come in and one pipe goes to inlet,has had half of the barb snapped of and vac pipe is not on very well
