I have a 1997 Audi A4 1.8T FWD, now a couple months ago my clutch dropped the floor an wouldn't come back up, aftwr about 10 minutes of pumping it, the pedal came back up and i drove it home, i bles the clutch thinking that was tge problem, well just a couple days ago sadly i had to get it towed because it decided to drop again an didnt come back up at all, got it home and tried pumping again an it came back up an hasnt dropped since, I've looked at other forums but was wondering what the common problem could be...before i go dumping money into a new clutch, slave an master cylinder i have checked my floor its not wet, ive checked underneath my car an no wet spots, should i just replace everything? Or what do you think it could be...thank you in advance!
