What's this noise please?

I have an intermittent squeal when accelerating (sometimes steady speed as well) at low speeds, I don't think it's the belt as it's road speed dependant not RPM dependant and can only be heard whilst in gear.

I've made a video where i am repeatedly pressing and letting off the accelerator to get a good recording of the noise https://www.youtube.com/shorts/YsCvIZIc-Ug

I had recently put on 30mm spacers all round but now taken them off as they were causing so much vibration so maybe they have put some strain on the drivetrain somewhere to cause this noise?

Let me know what you think! 2010 90 Hardtop

Any symptoms of the clutch slipping maybe? Are the revs rising by a greater rate than the speed is increasing when you accelerate?

No nothing like that, the car drives and feels perfectly normal. The clutch was replaced last April so I’d like to think that can ruled out

Thanks for your response 2010 90 Hardtop

I've listened to it again (and again) and the sound reminds me of a tractor I used to drive that had a dry bearing in the ventilation fan...I doubt it's that. lol

Can you replicate it when stationary or only when moving? Does the pitch rise as your speed increases? Does it do it in every gear? Does it do it in low range?

It’s definitely only when moving, the pitch does change with road speed but it’s only a small band of speeds where the noise can be heard hence the short squeals in the video as I accelerate though that particular speed (it’s around 25-30mph)

I haven’t tested in low range but I can do so tomorrow

Check the integrity of the pipes from the turbo to the intercooler and intercooler to manifold, and the intercooler itself. It could be a leak in a hose squealing under pressure.
