I have a Opel corsa utility four months old.Today the clutch suddenly lost pressure and I noticed a liquid leaking onto the floor,any idea what causes this it is still under guarantee and is at gm motors.

Take it back and have it checked. There is not telling what happened as it can be a number of things from loose fittings to a crack or blown line. Since its still under warranty let them repair it.

If the leak is towards front of the engine, the clutch slave cylinder or clutch pipe fitting is leaking. If the leak is below the firewall, the clutch master cylinder or fitting thereto is leaking. It takes only the slightest amount of air, since the system is so small, for the pedal to go to the floor. For long life, change the clutch fluid every two years.

Thank you for your assistance.
