99 a4 secondary air injector
mine whistles really badly on cold starts. is there a way i can remove it completely? supposing so, can i code the computer to forget about it so no CEL? is there a cheap way to repair mine if the above prove to be troublesome? lol

You could but you'll have a CEL unless you get a tune that removes SAI diagnosis. There's no way around it, no 'good-enough' hack. It monitors the actual airflow put out from the pump so there's no way to fool it through purely hardware means.
