i have this problem. my car is a 2013 grand picasso semi auto. 11 months ago i had a new clutch put in and has been driving fine since. but 3 weeks ago it went into limp mode. and then the service light came on with a message engine fault needs repairing. i stopped driving it and had a freind bring his scanner around.. it came up with the p1755 fault code.and clutch actuator position check faul-clutch stuck. so i have removed the actoator and pump but the fluid in the resivoir is black and smells like old engine oil. could the fluid be the problem as it don't look like the fluid that is meant to be used. any help would be brilliant as i don't know what to do next thanks in advance lionel399

You can try with actuator oil change. Selenia SAE 75W.
did you change clutch bearing when you changed the clutch?
