Hey y'all. I recently got a 1999 328i E46. I took it for a drive and the clutch stopped disengaging. Apparently it was having some trouble disengaging but still would. Now the clutch is not disengaging at all. I suspect it's the master/slave cylinder but even after removing the return spring on the clutch pedal the pedal still takes pressure to push down. Any suggestions would really help. Could it not be the hydraulic system?
Welcome to the Forum!
Just trying to understand what you are saying here. So when you press on the clutch, and release, is doesn't catch? Can you shift into any gear while the engine is running and the clutch is out? Or will it not go into gear with the clutch depressed?

Almost always this is a hydraulic issue.
Check fluid level in the reservoir, on some cars this is a shared reservoir with the brakes. If you've found the fluid low and it is a shared reservoir this could be normal as the fluid level drops as brake pads wear. Simply filling the reservoir can restore clutch action if this is the case. The system is rather self bleeding with time and use.
If fluid is low check for leaks. A failed slave cylinder will leak into the bell housing so fluid will drip out between engine and trans. A master cylinder can fail and NOT leak, the leakage being internal. A leaking one might not be readily apparent as the sound deadening pad on the panel above the pedals can absorb quite a bit of leaking fluid before you ever see a drip.
If a shared reservoir don't discount the possibility of leaks in the braking system that are depleting the reservoir.
The most common failure, if any, will be the slave cylinder.

If you can leave two black stripes from the exit of one corner to the braking zone of the next, you have enough horsepower. - Mark Donohue
I have the exact same problem. New clutch kit new slave cylinder. You can feel the lines and hear the slave but it won't do anything. I can't put it into gear while it's running and it won't cut off

Feel the lines and hear the slave? What does that mean?
If you replaced the slave, what procedure did you follow? In what way did you bleed the system?
