Hi My turbo (newly installed with only about 1000km) in my Audi A3 2.0tdi (BKD) is whinning (NON-metallic sound...more of a whhoooting sound). Whenever I DETACH the vacuum line of the turbo's wastegate to the solenoid block...the sound DISAPPEARS!
I bought a NEW Solenoid valve block (the one with 6 vacuum lines attached to it) and installed it..but the problem did NOT go away! the whinning sound is still there unless i detach the vacuum line to the wastegate as I did earlier.
I also inspected the impeller of the turbine but they seem to be OK.
I checked for fault codes using my VAGCOM but there was none.
Where else should I look?? Thanks in advance!
