Brake fluid leak

[mmisch]

Hello, since a few weeks i got a brake fluid leak somewhere and i since 2 days now i basically cant drive my car anymore since the clutch stays at the bottom.

here's a few keypoints on whats going on:

WITH THE CAR OFF:
clutch pedal works normally as it should, no problems

WITH THE CAR OFF AND NOT STARTED FOR A FEW HOURS:
brake fluid is not dropping when topping it up

WITH THE CAR OFF BUT HAS BEEN STARTED BEFORE:
When filling, the fluid doesnt drop?


WITH THE CAR ON:
If i depress the pedal for less than 10 seconds its it will return on its own
if i hold it longer for 10-20 seconds, the pedal with go halfway and wont come back, unless i put it back up manually
This issue happened to me also while driving, and when i hold it for 10/20 seconds, i cant also shift anymore, and the clutch biting point will be at the absolute lowest point
and the car tries to drive forward by itself with me having my clutch pedal in, but in the meantime the car also tries to stall, so the only solution for that is; turn the car off>manually put the clutch back up>i can shift again out of gear to neutral> start the car>drive away asap




other info:
- No wetness at master cylinder, bone dry
- after cleaning it all up, i found fluid drips on the bottom of the starter, a bit of wetness on the breather block thing (but that could be from me bleeding the clutch which did not help) and on the front of the gearbox itself, also a bit of drips on the ARB

I got a leon mk1 2005 1.8T AUQ, with a 02M FML 6 speed gearbox, and i better hope its not the slave cylinder since its CSC

If it is my slave cylinder leaking somehow i will get the clutch/pressure plate done too since the box is already out


here are some videos i took:

anyone got some things i could check or advice? thanks

if you have brake fluid on the starter then it could be coming from the bleeder block and dripping down. I have had no end of issues with these stupid things myself. If you recently took it off or messed with it chances are it wont seal properly again.

First thing to try is get some brake cleaner or whatever and clean that whole bleeder block and area bone dry, as well as your starter. top the reservoir up, bleed it if you need, try use the clutch pedal and then check that area again after some use or a couple of days. You can just feel around the area with your hands and check for brake fluid. If its wet and sure its coming from there then you should:

Get a new bleeder block and the correct O ring and the other weird top hat shaped rubber seal. Get them from your local VAG dealer or somewhere that sells legit genuine stuff. Cheap seals and O rings will just send you back in there fixing the same issue. Even a slight leak of just air in this area will make you lose clutch pressure over time.

Okay i will look at the breather block, i havent taken it off yet, since you need to bleed it again after removing, right?
I did try and bleed it but didn't help.

also i did some test today:

Basically:
1. I pressed the clutch for 20 seconds with the car off > nothing happens, the clutch works perfectly, as it should.

2. I started the car, had a cold start > held the clutch in for 10 seconds, and it go back to to halfway and stay there

3. I lowered the pedal (halfway) and turned the car off, then manually raised the pedal and pressed the clutch again for 10/20 seconds, nothing happened at all.
