Make sure whatever hose you use in that spot is capable of withstanding reasonably high temperatures and boost. I used generic vacuum hose from one of the local spare parts sellers and found that the hose had turned to jelly where it joins the metal intercooler pipe.

Glad it's sorted. Another area to consider when fault finding.

Those 3 pipes (And the actual modulator) are the cause of MANY issues, it is one of the first places I go to to check overboosting or lack of boost in D2's.
All the pipes need to be in good condition and clamps tight. Obviously the valve needs to be functional, too.
