Only happens about 50 yards from my house and has only been happening in winter. After 2-3 minutes it goes and wont happen again that day!

Only starts when engine going into idle then as soon as any revs come in the noise goes!

video below

any ideas anyone?

many thanks!!

 

Exactly the same as mine. I changed both the aux and supercharger belts. Checked both tensioners and pulleys. All okay. Still does the squeel although not as often. I put it down to a characteristic of the car because I now know I have no faults.

 

I could only hear some nasty rattling in that vid.

 

that is just due to the video, the sound is definitely more of a squeaking/ squealing sound.

Im putting it down to a cold damp belt at the moment

 

 

What do you say guys? Sounds like the SC coupler.

 

that's way too loud to be coming from inside the engine

 

Sorry when I say inside the engine, I basically mean the main block in the middle. Its something in that area but its really hard to see under as to exactly what its coming from.

 

After searching for other videos relating to SC coupler I think you may well be right there!!
