I dont feel any resistance other then the return spring from the pedal, I do believe it is a hydraulic issue but not sure

I'm not familiar with BMW MINIs, but it does sound like your clutch hydraulics have gone out. I am assuming you de-clutch using a foot pedal.

If it is a hydraulic system, it will have a reservoir - check and refill the fluid level.

If the fluid level is up, and you can find no leaks, check the clutch end of the system to see that the slave cylinder is actuating the mechanical parts of the system. A mechanical component (lever, release bearing etc.) may have failed and the hydraulics are pushing against nothing.

If the slave cylinder is not actuated when the pedal is pushed, the master cylinder or the linkage to it may have failed. Does the pedal seem softer than normal - can you feel any pressure point where the system starts to push against the strong clutch springs.

I have a 2008 manual and I was driving the other day and went to downshift on the freeway and I have nothing, feels like no clutch, I cant shift or anything, would a clutch go out just like that without warning, or is it something else, master, slave cylinder ? and how could I check that ?
