So after a drive in my RS4 I noticed that the clutch pedal was sticking, and as I changed to 3rd it stuck altogether, made some upsetting noises during changing and since then hasn't been right. It's been making a grinding noise as I've been shifting into gears but hasn't failed to get into gear, and after a while it actually got better and better but I still do feel and slightly hear a grinding noise when setting off and changing gear. Could this be the slave cylinder or the clutch? I thought it may just be the clutch pedal re-adjusting (which I've had other problems with) but the grind is still slightly there. Cheers.
