Air noise when on Boost ???
I recently changed all the vacuum hoses on my 1.9 JTD 16v (150) and all was well. Cured my annoying over boost MCSF etc....
Anyway driving on my normal run to work today and pulled up to a junction. When pulling off i noticed what can only be described as a rushing of air type noise, as if the fan is on full speed. Slowed down Noise gone, speed up and noticed it only comes back when the Turbo kicks in.
So I have just been out again and the car drives fine, just that on boost this air rush comes in and it's as if the Turbo is spooling into the cabin ?????
What on earth is going on ? Any ideas ?
Only thing that's been changed was the pollen filter at the last service and i also did the silicone hoses but it's such a noticeable amount of air surely these can't be related ?
