Vac lines like to split. Make no end of problems.
Id start there. Simplify the breather sysgem while your there. Id also change the recurculation valve and turbo intake pipe to silicone item.
Theres plenty of threads to go off. When replacing the vac lines you can get it 2 3 and delete the n349 valve while your there.
Basically under inlet to fuel regulator
Other under inlet to dv
N75 lines stay the same routing
