ever so ofen my clutch sticks to the floor and will not shift into gear on my 1993 bmw 325i, what could be the problem?
I would guess you have a faulty slave cylinder.
Or a faulty master cylinder. When I replaced the master for my '88 Supra, several people advised me to replace both the slave and master cylinders together. Glad I did. Only cost me $100 for both parts, and a couple of hours to install.
