Low moooing noise
I have this weird noise since i got my 99.5 A4 1.8T. Didn't really care about bcuz i thought it's normal, but these days it's really driving me crazy....
I have used the search option and i found a lot weird noise post but none of fits....and i checked engine code with no code pop up....
It sounds like low moooing noise from engine bay somewhere. It's not the sound which engine makes when you downshift..
Can't hear it when the car is stationary, and start to notice it around 40KM and then 70KM and gets even louder over 120KM. i can even hear it with radio on when the car is over 120KM. No matter on what gear, RPM, even in nuture the sound doesn't change its pitch.
My friend is always complain he feels dizzy when he is in my car , and i think that's becuase of the noise.
My car boost at 6~7PSI, peak 8PSI...and vaccum 13~14 at idel...about 12~13 when driving.....
anyone experience this noise too??
need some help from Audi people..
thankx
