It's an 2008 ls3 and recently the clutch peddle will only come back about 90% of the way. There is a little bit left that i have to push back with my foot. I check the clutch fluid and it was dark and low so I changed it with some dot 4 now it's clear and full. The funny thing is it will start working fine about 15-20mins of driving. What can be the cause of this?

How would I be able to tell which one to change though?

Check to see if the pedal return spring is broken or missing. Mine was missing and I was getting P0833 codes. Easy to replace.

That would be the spring on top of the clutch peddle I'm assuming but unfortunately that's the first thing i checked and its still there.

Bank that the clutch pedal assist spring broke or was removed.



If missing or one leg broken off, replace the pedal assists spring to one for a C5, and don't forget to grease the hell out of the spring, it U clip and side legs clip points so it does not make noise when you use the clutch pedal.
Smaller C5 spring on the right.

Don't use a cheap DOT4 brake fluid like autozone or napa. brands

I use Castrol SRF but its rather expensive. You can also use Motul 600. They have a higher wet boiling point than the cheap stuff.
