I have a 2000 audi a4 1.8t with an apr chip
i have about 103000 miles.
got a new turbo right around 1000 miles. stock k03. we were sold a new one but from what i've heard about the shop, it could be rebuilt.
my question is, how loud should the whistle be. I was told by an audi shop that i was pushing too much boost, around 20psi at the most. then again this is an audi shop that only sells mtm and has been know to be not the most honest shop.
It shoulds like a really loud highpitched whistle more so than the woosh. its like the rotor inside is rubbing against the side maybe?
Is it possible for a turbo to burn out that fast? is it normal for it to be that loud? I did the airbox mod(drilled some holes on the prefilter side, other than that everything hasn't been touched. let me know and many thanks!
