I've tried searching other places but for some reason my computer is blocked form almost every audi forum, its been giving me weird internet issues like that for some time. Short back story, stock k03 was definitely on its way out bad. So I installed a new K04, runs great.. only concern is that under wot at about 5k rpm it hits like boost cut or spark cut or something.. I'm assuming i may be over boosting so i've been staying out of it until i can get it returned, which is a whole other story all together. Is this a common issue? what is a fix for this? Also, after hitting that wall at about 5k my car has now developed a weird moaning/grunting/cow/whale noise under the hood. At first it seems extremele random, but now the more i play with it the more it seems like it makes the noise under tip out throttle, Its specifically bad cruising at like 70-80mph and is almost a consistant noise that i can modulate with the throttle, i can almost feel the noice in the floor, or pedal, It almost sounds like a diaphragm is going bad or something, anyone heard or this and may have a common fix? Its a MFer to diag since it will only do it underload, and i cant get it to do it by powerbraking the vehicle. 3rd question is just something thats kind of been on my mind and bugging me, I cant seem to find the map/boost sensor to save my life. Again i cant get access to any good information cause my computer hates me, but what i have been able to gather is that it should be on the factory intercooler. I don't see it there, or anywhere for that matter. any suggestions, besides open my eyes? All and all i think thats pretty much it so if anyone can help out it would be greatly appreciated
