01 s4 chip problem

[Randy255]

i just put in a stage 2 chip and for some reason it goes in and out of limp mode and idk why i just got this code number p1555 i see its a boost pressure control upper limit exceeded i found the causes and symptoms and stuff on ross tech wiki but idk which one it is i dont think its boost pressure too high cause that makes no sense i believe that one of my hoses connected to my solenoid valves the clips broke so i zipped tied it on could that be my problem? maybe its leaking from there? if so where would i get a hose like that? answers ASAP please.

umm.. why didn't you clamp them?

just pressure test the car and you will find where its leaking from.

idk just did today there was a tiny leak from there but still chip goes in and out of limp mode could it be the hose to the solenoid valve

Your N75 could be bad.. you might have the hoses going to the N75 on wrong.. fix the cheapest things first and one by one youll get to the bottom of it.. hope fully its not one the hoses going to the wastegate from the n75 behind the motor next to the firewall if thats leaking theres not enough pressure to open wastegate and you will overboost..
