    A bad cylinder will let air in quicker than fluid can get out. Just had it on a KA, no loss of fluid but needed bleeding every couple of days, slave cylinder replaced in box and good as new.

    It's sloppy because air compresses and requires little leverage to do so. So your compressing the air with the first inch or so of the pedal (the slop) then moving the thrust bearing with the rest. It's start to grate when putting it in gear soon enough too.

    Master cylinder can also cause similar issues if seals inside fail, but you will usually see bubbles and/or a change of fluid level in the brake fluid reservoir when you push the clutch pedal down.

    Don't have sby experience with insignia clutch just corsa ones. Does it share the brake fluid like corsa do? Either way when was the last time the fluid was changed? Might just be badly contaminated and needs a change. If your gonna bleed it anyway empty fluid out of the container and run though new fluid.

    On the smaller corsa the slave cylinder is concentric ie in the bell housing, while the bigger engine do cars it's external. So much work to change will depend on where the clutch is located.

    Yeh the clutch fluid shares the same as the brake fluid, I only found this out the other day. I'm going to bleed the system the second I get chance. I'm going to call the AA out this evening for their opinion. From what I can also make out the master cylinder is internal to the bell housing, so if it is that that's at fault it'll prob be worth replacing the clutch too

    If I remove the cap from the fluid reseviour, depress the clutch is that likely to show air in the system or is there's possibility it will suck more air in?

    I don't know when the last oil change was done to be honest, I've only had the car for 5-6 month, And the last service was in 2013 which actually shows an oil change was done then. So presumably 2013, recommended is ever 2 yrs I believe?? So well overdue.
