94 525i a/c belt noise

[floydturbo]

I have a somewhat intermittent a/c belt squeal. It happens when the temperature is hot and at low rpm situtations, usually at idle. I have replaced the belt and tensioner and also checked the spring tensioner. I added oil to the cavity of the belt tensioner. I also cleaned the pulley with brake cleaner. Anyone else have this problem and solved it???

I had an intermittently noisy belt. I changed the compressor clutch and it went away.
