2003 New Beetle P1556

Daughters car went into limp mode tonight with check engine... tossed it on the VCDS got P1556. Wild Rose put a brand new turbo in it last July so I am surprised at the code any thoughts?

Negative deviation so do a visual inspection of the vacuum system to rule out leaks.
The new turbo shouldn't be acting up but make sure the vent hose to the airbox
from the N75 is connected. If left loose dirt can make its way into the valve.
Other failure points are the vacuum tube to the brake booster and the pump flange.

Will start out replacing hose... I have a jetta also so next I will pull the N75 off that one & give it a try.

Changed some raged looking vacuum hose for now & cleared the code & seems to be running well so hopefully that cleared up the problem.
