Engine Wine After 3000Rpm

[Sedcokreep]

Soooo I'm back here again....

I still haven't got the flywheel fixed and nor am I going to BUT I have another new fault.

On my way home last night I was on the dual carriageway and decided to overtake a '40 miler', I was greeted by a weird wining noise from the engine. I knocked it out of gear and revved the engine to hear the noise again. It was happening at anything over 3000rpm and more so at 4000rpm, not that I drive that way normally but I tested the sound out to give me a better understanding.

I left the car until this morning and it seemed fine. This afternoon it is doing the same sound but not as severe.

The sound itself sounds in time with the turbo but I can't be sure as it when the engine revs creep up. It could be a belt, I really can't tell. It sounds like a when you hum and whistle at the same time, if that makes sense but get louder and more high pitched with the revs.

Has anyone had this happen before??

I really can't wait to get shot of this car...

Sounds like your Turbo is shot but without hearing it everybody will be guessing. Maybe put a quick vid up of said noise?

Also when were the belts last changed?

[CHUNKY CHIP]

Just to ask does it sound like an old kettle whistle as it boils it gets more high pitched ?

also does it have a peak does it stop at a certain point or keeps getting louder harder you drive it?

have you look at any pipes under bonnet a split usally shows after x amount of pressure builds (whistles also)

Hi guys, I thanks for the replies. Great forum. :-)

On closer inspection last night, it sounds more like a belt. Definitely not the turbo as that's kicking in at much lower revs.

On the way home last night the noise came on again so i kept it in 3rd up to 70mph and just sat there; the noise went away. IMHO I think its a belt... Off to the garage we go... again...

Honestly, the things that have gone wrong on this car in only 50k miles of motoring are laughable.

**UPDATE**

And now the engine management light has come on with a sign saying "check vsc"... What a truly brilliant car...

You need to get the code of the fault to discover what the VSC refers to.

It can be a mutitude of things. I had aVSC due to a broken cable on a engine manifold sensor. 20 minute fix, wipe the code and bingo , job done!
