Funny Noise

[pug1968]

Hi,

Anyone came across this. Got a 307 1.6HDI and occasionally when i pull away, mostly on hills i get a high pitched squeal coming from the engine, i assume it is clutch related. Have had it to a garage and they got it to make the noise once but they are at a loss as to what it is. It is so loud that passer bys look.

Its annoying because it can go days without doing it then off it goes and squeels. To me it sounds like a dry bearing, garage checked the release bearing and found it was ok

Help !!!
