I have a 94 325i and recently, my clutch pedal lost all pressure over a 4 hr period. Under the car was a leak, but not sure where coming from. Is there a separate reservior to service the clutch than the brake reservoir? Will I need to bleed the system prior to driving? The pedal completely sticks to the floor when depressed.

There's a master cylinder above the clutch pedal, and a slave cylinder mounted to the left side of the transmission. The bleeder valve is on the slave cylinder. That's about all I can tell you, I've never worked on the clutch myself. Maybe someone else can chime in here . .
