Ok this started a couple of days ago and scares me slightly
When i depress the clutch pedal i get noise, not grinding or chattering more an engagement whir, almost a rattle but not quite, sort of louder engine soundish (sorry if my description doesnt help). It goes when you release the clutch pedal and are in gear. Also when you depress the pedal it feels lumpy? The pedal is also quite heavy.
Im thinking the slave cylinder thingy but not sure. Car is a 1990 325i m20 engine.
Please let it be something simple
