Default Strange noise

Guys, what could that be??
It takes around 10-15min for the sound to appear when engine/bay gets up to temp. It is on the driver side and I think more bottom part.
Really hard to tell coz the sound is really high pitch which is what you can't hear in the video as much.

Thank you in advance

file attached.

All I can see there is alternator.
It can't be fan as the noise goes away when I rev it ?!?!

Sounds like it could be belt squealing or altenator bearing.

I haven't listened to your video, but have you checked the PAS fluid level. The reservoir is buried and consequently often gets missed in servicing.

If it was Dezzy's car then I would suggest that you remove the pig from the car and instead use a trailer to take it to the abattoir.

Does the D3 have a viscous fan? The coincidence with achieving running temperature and the action of the clutch mechanism on such fans might be something to investigate.
For Dezzy: A friend of mine tried to take his pig to the abattoir in the back of a Clio. Lets say that the journey didnt end well for anyof them - including the car.

I'm sticking with belt at the moment, just needs a slight tighten up. Easy fix

David. I'm not supprised the pig was protesting, a Clio! I would have rather have ridden the pig, athough getting home might be an issue.

I had a similar sound that disappeared when revved. This was on an A4 and it was the water pump. Have you a mechanic's stethoscope?
