Cluch pedel gos to floor - 1994 Volkswagen Jetta

It could literally be several things. Have you been having clutch problems lately? Normally clutches show signs before going out, but there is always other things that can go wrong. Depending on weather or not the clutch system is cable or hydraulic. Hydraulic clutch system works the same as hydraulic brakes. Their is a master cylinder that pumps fluid pressure to a device. In the clutch though it pushes a metal rod into the slave cylinder to release the clutch disc from the flywheel. The easy way to think about a clutch system say most people can understand it is. Clutch works off friction. If you have friction you can go, if you don't have friction well your not going very fast or far. An the clutch disc is lot a huge brake pad but instead of stopping you, it's friction cause you to link up to the engine flywheel and go. If you know how something actually works then you can probably self diagnos the problem but to help you here is a list of things it could be. Clutch pedal cable to transmission broken or bad, slave cylinder, throw out bearing, clutch master cylinder (if equipped with hydraulic clutch), pressure plate, or clutch disc. But the only true way to find out is to remove the trans and see for yourself. Hope this helps.

You could need a new clutch or clutch fluid or they just need to be bled
