Weird whine type sound on any +1250 rpm

[Sylux]

Hopefully you guys will be able to help me with this.

It's pretty quiet (but enough for me to now notice) and sounds like radio whine (best way to describe, I think). It's not there on idle but as soon as I give some revs it appears. Neutral or driving.

I stays the same pitch throughout the gears.

Sounds like it's coming from the passenger side of the front console.

I know this can be one of those "need to hear it in person" things...but was just hoping.

All the best

Is it radio whine?


Possibly blower fan bearing, have you tried the fan speeds?

[Sylux]

Yeh, radio whine was the thing I thought of first Not that as it's fine and earthed well etc.

Blower is a good call...but I'd also messed with that. At low fan speeds it can be whiny. But it's a separate thing as slightly higher fan speed rids that noise and the one in the OP remains.

This is linked to the engine speed.

I remember reading something, on here, that involved a bearing in the engine bay (or something )...but can't for the life of me find it.

Just double checked...it's +1250rpm. Comes in at exactly 1250.

Hope it's not a Turbo problem.

Sorry fella does the noise increase with engine rpm?

Could be a loose air hose ?

[Sylux]

Not sure what you're sorry for. You're trying to help But not really (sound increase)...it kind of comes on and stays the same. Pitch stays constant but maybe there is a slight, slight rise in noise...but the engine gets louder and it is washed out.

Any chance of recording it?

[Sylux]

Tried...but you can't hear it on the recording.

The outside one is super short but you get to hear it or a similar sound which matches.

On the second rev. But I couldn't hear it (outside the car) so stopped recording

Might be something simple like one of the drive belts, although like you said nothing really sticks out.

Have you checked all the drive belts?

[Sylux]

Yup...everything seems fine.

Shame I couldn't capture the sound inside the cab. It's far more isolated as the firewall insulates the engine noise away...to some degree. Phone just won't capture it.

Is the noise still there when the passenger seat is unoccupied?

That's the thread I was referring to, earlier!!!!

Looks like I found it via here and not on here...but all the same, that's the boyo.

I'll give that a bash.

Top man, thanks very much
