Peugeot 406 Clutch Noise - john406
My 1998 1.8LX 406 (40,000 miles) has developed a high pitched whining noise when the clutch is on the point of engaging. It goes as soon as the clutch is fully engaged and the clutch is working OK. I am surprised there should be any clutch problems at this mileage.

Any ideas what is wrong?

Try deliberately slipping clutch to burn off any contamination - the noise may magically disappear

I'd be concerned about the release bearing, although the symptons are slightly different from normal.
