My wife bought am 03 C3 1.4HDi around 4 months ago with around 35,000 miles on the clock. Today she called in a panic as the car was sticking in gear. 1st and reverse are the problem. The car has to be switched off in order to get it back into neutral. Then it runs fine for a while only to run into the same problem. Anyone else encountered this? Could it be the slave cylinder?
