Whistle sounding like blow off valve - MY95 - 10-05-2015
Most of the time when I come off the throttle to change gear I get a blow off valve noise (i dont have one fitted) any ideas what it could be?
RE: Whistle sounding like blow off valve - Piggy - 10-05-2015
dying turbo possibly.
intake pipe to turbo has come off.
RE: Whistle sounding like blow off valve - MY95 - 10-05-2015
Had this turbo on for only 6000 miles, was in good condition and only done 63k
2nd one is a possibility
how can I check this? Easiest way without removing subframe etc?Cheers Piggy

I also have this problem but think my turbo is dieing lol it's done 190k! Still boosts fine tho

Easiest way to check the intake pipe is to have a look, run your fingers around it to check there's no gap. Can go in through the driver's wheel arch.

play in turbo centre bush??
haynes manual suggests some may have an oil feed line filter??
shaft floats on oil pressure and bush?

Where can I get one of these bushes from? May be turbo upgrading in the next 6 monthsor so so is it a thing needed to be done asap or not?
Cheers

The central shaft sits on bearings, you can get new bearing and seal kits from turbo specialists. It's a pretty involved job, not worth it for six months use imo.
