2002 audi a41.8tqtm i was leaving walmart on saturday and when i shifted from 1 to 2 it didnt go and wouldnt go into any gear get it towed home bled the system with the pump the pedal method and it worked on sunday on monday it was back to not working i bled it again after installing a new slave but no change this time dont currently have a pressure bleeder havent found any close to me might build one tonight but i was looking for some more insight to make sure im on the right track i dont know what else it could be if not a hydraulic issue

 

did you bench bleed the cylinder? when u press the clutch does it sit at the floor or return?

also if you put it in gear while holding the clutch, with brake off will the car start or try to roll?

 

i bench bled it the best i could, pedal feels the same as it always has which is the worrying part it never went to the floor during the whole procedure i'm going to try bleeding it more tonight

 

well bled some more wasnt going anywhere tried starting in 1st and r just rolled started it in 5th and it started and no major roll. then it shifted fine took for a test drive and worked fine hopefully it still works in the am this time im still confused on why its so wierd any other input would be welcome maybe a failing master cylinder my car does have almost 210k miles on it

 

jack the car up and look at the slave cylinder rod is installed correctly. did you change the rod when you changed the cylinder?

 

new slave came with rod(new slave looked same size) but it was a duralast. i put it straight in little bit of fumbling to get it in but i did take it on a 150 mile round trip today with only one hi-cup i guess i need a pressure bleederto get all the air out i would have thought the two small cans of fluid would have done that, maybe ill seperate the feed line from the brake reservoir and give it its own

 

maybe try the old rod you had.. when i installed my clutch, i had to open the bleeder screw to put the rod on, but that was because the rod is longer than the oem b6.

 

I've had this before. Mine was a broken spring in the clutch disk. The small peace of spring was wedged in between the clutch disk and the flywheel. Sometime released sometime it didn't. Tried new master and slave cylinders with no help. Just a thought.

 

those springs are just there for dampening.

 

still working i think my slave was just bleeding out so far so good planning on replacing clutch when tax time comes around hopefully
