1987 S3 HCI (turbo ?) whistling

Recommended Posts

Hi Everyone


There is a harsh "whistling" that comes from the engine bay when I change gears up at high revs

(from around 4.000 rpm)

I suspect this comes from the turbo , any ideas ?

It is the screaming type

Short but very loud when I change gears above 4.000 rpm

I was also thinking of turbo worn bearings ?


Anyway thanks everyone for your help

He the hoses off and check for end float in the turbo impeller

Any wobble will be obvious,, make bad noises, and usually go bang in a few hundred miles

Take not I the only one that has issues on iphings !!

Only here once
