2001 A4 1.8T triptronic with boost problem.
Hi I'm newbies here.
My brother own B5 A4 1.8T. It's used car.
Today I drive the car and feel like the car is not spooling hard as it should be (I assumed that it should be more faster)Since got the car. the car had boost problem.the car was running with 0.1-0.2 bar and finally it's caused from the wires that go to the WGFV.
after fixing the wires.the max boost is @ 0.5 bar(rarely 0.6).
what done?
All vacuum hose,Autobahn silicone hose set.new BPV 710N.
even with WOT the car seem runing like a crab.
Anyone experinced this before.What's the first
thing to be done?
The car is all stock with K03. My next guess would be the WG.pls lighthen me up
THX.

Re: 2001 A4 1.8T triptronic with boost problem.
have you reuled out the mass air flow sensor. A failing maff can cause a 1.8t to fall on it's face when you get in the throttle. You need a vag-com at minimum to check the maff. Thats where i would go next. Some engine codes have an extended warranty on the maff. check into it.
