Stop confusing yourself.
True, there are two hydraulic systems that use the same fluid and they are both adjacent to each other in the front trunk.
BUT…….
is the fluid level in the BRAKE master cylinder also going down? You made no mention of that, but now you are putting it forward as a possibility because someone else changes the topic to brakes when the topic is about clutch leaks??
really?????
have you enlisted the help of a second person yet? please do that before you start running off on wild goose chases
perhaps putting down a layer of newspaper in the front trunk, which will be a better indicator of leaking fluid, is something you should consider.
I developed my troubleshooting skills as a union electrician. It is a skill that not many actually possess. it involves making absolutely zero, Nada, no assumptions!
You have apparently discovered fluid is disappearing from your clutch master cylinder. This is your starting point
