TDI 2.0 Turbo screech time to upgrade?
Hello im new to this forum but have been searching various sites for an answer to my problem so i hope someone can finally help.
I have a 2004 a3 2.0L tdi sport was originally 140bhp and was rolling road remapped six months back to 185bhp with no problems, until now.
The turbo has started this nasty high pitch screech when it cuts in its so bad i had tinitus the other night after a drive, i am guessing the bearing is going it still pulls but not as well.
My question is, as i need to replace the turbo can anyone tell me if a larger turbo from a tdi 2.0L 170 quattro will directly fit mine or do i need to change other parts?
I am only thinking the larger unit may be better as its designed for the more powerful engine and i dont want to damage another standard 140 turbo if re fitted.
All feedback appreciated!
