Dump Valve issue

Post by NotoriousLor »

Just fitted a forge dump valve to my 207 gti, it is an atmospheric valve so should make a sound when coming off the gas but doesn’t.
I do have the dreaded depollution system faulty message occasionally but when I reset everything the turbo is working but still no sound from the valve.
Does anyone know if the depollution system thing could be stopping it from working correctly?
