My wife has a 1.3 CDTi 90 that has a turbo whistle does anybody else have it. The whistle is more pronounced above 2000rpm. Have taken it back to Vx who replaced turbo but it's still there. Any suggestions. Please!

I remember this on a old escort i was working on, it had a leaking seal going into the turbo and when increased induction began, the force of the air being dragged in made a whistling sound. does the vehicle have slight loss in power? if so have a check over the fitting of the turbo and if not, run a compression test

whistle only happens when the turbo kicks in. its kinda like a blast valve thing.

Check all the piping to/from the turbo. Only if there is a boost leak there will be a loss of power. Any loose piping on the turbo will cause a whistle. I fitted a cone filter to my 1.5 TD corsa b and the turbo screams. Don't forget to check both inlet and exhaust sides of the turbo

I have the 1.3 CDTI 90 - the turbo does have a slight whistle, but not very load at all and you have to have the windows down to hear it.

All turbo dervs will have a very slight whistle, if it is very load and you can hear it with the windows up then you may have a problem.
