Vauxhall Corsa issue with clutch pedal not rising

It is a know issue with that car . If you look at previous replies to this problem in our Corsa archive section you will see this . Doubt very much it's clutch pedal return spring . if so it would do it all the time and would be a simple fix

According to Haynes [^1], it's commonly caused by insufficient grease on the gearbox input shaft splines; got the same issue here on an '08. I'm assuming this'll also apply to newer models.

Given all the stories I've heard of people spending hundreds on replacing clutch parts only to find the issue persists, I'm inclined to believe this could indeed be the root cause for most people.

The solution you suggest has nothing what so ever to do with a clutch pedal sticking down as any mechanic will tell you .If you knew how a clutch operates , you would realise that . The input shaft splines " fault " which is common on ANY manual gearbox has been around since I was a boy and involves the operation of the clutch centre plate sliding on said splines which is addressed / checked when anyone qualified replaces a clutch .This causes a different fault all together
