If the fluid was at the min mark I don't think the light would trip. I'd
be more suspicious of a master cylinder failure or worn out break pads.
Have you checked the pads?

And no, there's no overflow hose that leads into the interior of the car.
I can't picture the engine bay of an E30 in my mind and can't remember if
the master cylinder is in the bay or inside of the firewall. But, I think
it is in the engine bay. I think the clutch master cylinder is in the
passenger compartment. Maybe the return hose from the clutch has a fault.
But even so it seems you'd have already known about that...
