Technical Can P0235 be because of leaking interculler or hose? Turbo goes off at 3000rpm

Hey i have an issue on stilo jtd 115. On highway, 5th gear on boost arround 2500-3000rpm i got instant red check engine fault and turbo goes off. Check engine Light goes off immediately, but comes again if i accelerate hard again. You need to change the gear again into 5th gear to exit safe mode(turbo off).

I have P0235 code fault. Can this issue be because of my intercooler maybe leaking… it is oily under and i spotted oil drops under car. Also i can see a verry little crack on bottom intercooler hose which goes up. I am not hearing hissing sound.

I dont want to replace everything with this issue not fixed after…

I would suggest a "smoke" or a pressure test of the induction side, from turbo to engine.

Just to inform: I replaced the intercooler and boost solenoid valve and problem is fixed. Also there is no more black smoke behind me.
