I'm working on my clutch problem.

I bleed all the breaksn and slave cylinder.

I dont know how to bleed master tho.

Anyway my question is what is this thing adjust ?

Is it master cylinder?

Can I adjust with it ?

There are som numbers on it.

Other thing is;

While car is running;

If I want to switch the gear from N to any gear a "pssss" sound comes from engine or around. when the sound stops i can put the gear easily. I always user extra power to chance a gear. if i wait till "psss" ends (it takes about 3-4sec) then gear goes so smooth into. I feel like clutch take time to disangage from fw.

When I leave the clutch pedal then I hear another "psss".

 

Ahhh welcome to the world of the worst slave cylinders in the world, audi has the hardest clutch system to bleed on the entire planet besides SAAB. The ONLY way to get the slave cylinder completely blead is to use a pressure bleeder on the master cylinder and crack open the slave cylinder bleeder and let it bleed off while you push the pedal with your had about 20 times. Sound stupid? it really is, to get the desired feel it usually takes about 1 gallon of brake fluid to get the slave cylinder blead correctly. Thats why we never take off the hydraulic line to the slave cylinder when we replace a clutch. Don't mess around with the master cylinder.
