I read somewhere in here that on a stock A4 1.8t you should not hear the turbo spooling. Well when I hit the gas I can clearly hear a whistiling sound like a turbo. It is much louder at night or when it is overcast and not as hot as the regular afternoon. Is this my turbo and if so, is it a bad thing that I can hear it?

 

It's all good.... My car does the same thing though i may have a boost leak.

 

you should be able to hear the turbo a little bit. its not lound on the stock a4's, but you can still hear it

 

mine is pretty loud and with the windows down can even be faintly heard while doing about 80. It has sounded litk that since I got it. Other then the boost leak test what are some other tell tale signs of a boost leak??

 

yea its ok man you should be able to hear it, just not like a freightliner

 

I wish mine sounded like a freightliner

 

mine does...... on my truck, lol

 

you should be able to hear it. especially in 3rd and 4th in the sweet spots.

 

Does the car drive OK? Is the power still there? If so, dont worry about it.

 

Get an intake or k and n panel filter and chip, thatll make it sound sweet.


Slightly off topic question, but how loud is the K04 turbo with appropriate
chip ?? Is it much diff then chipped K03. just wondering.
