I got 99 passat and it all ways fluter ch chchchchh sound every thing fine vacum hose idk thanks
My A4 1.8t AJL makes weird sound. Check from my channel, because i couldnt but the link on this. I think its from the wastegate because the sound comes from the turbo I think. Someone said it could be the N75 valve. Is that sound known to you?
how was the car acting before you replaced it? cuz mine is a 1999 audi a4 quattro and i put an aftermarket intercooler with a blow off valve but its still running low on boost..my turbo is not kicking in on time..help plz
I recently had my 03 a4 apr stage one chipped. I am getting a 16683/P0299/000665 – Boost Pressure Regulation: Control Range Not Reached error and looking for any help to fix it. The car is running good but want it right. Thanks for any helper comments you have.
after the video I replaced the turbo manifold with a good wastegate and it has worked fine every since. I paid like $90 shipped for a turbo and turbo manifold off a 03 passat or something and just swapped the entire thing.
hey did u ever fix your boost problem yet
