2.7t boost trouble

jenyus425 · 03-18-2012, 11:51 AM

Hi all,

my 2001 allroad 2.7t is having some boost issues and the worthless local shop can't figure it out. the car feels like it boosts well from about 2k rpms to about 3500 but then it seems to falter and the power kind of fluctuates. ive replaced the diverter valves and checked for leaks the best i can but without a smoke test i don't know a real good way to test for leaks.

is it the n75 valve maybe? it seems like maybe the wastegates are opening too early or something.

i installed a boost gauge on my 2.7t and most of the time im getting 9-10 lbs of boost but sometimes its only about 4-6 lbs of boost. i also have new diverter valves

okay, yeah i should probably put a gauge on there so i can more accurately diagnose whats going on. where did you plumb the gauge to on yours?
