  • [Corsa D 2006-2014] is the clutch slipping

    Hi All


    my wife has a corsa D1.2xi,you helped with headlights, now when she is driving and changes gear the revs go up then change gear again revs go up just a little


    is that a slipping clutch thanks

    Simple way to check for a slipping clutch is to apply the handbrake firmly, stick it in gear, set the revs to about 1500-2000 and slowly let the clutch pedal up. When you get to the bite point try to keep the revs level. If the clutch is good either the engine will stall, or it will pull against the handbrake, either way you ought to feel the clutch taking up drive.

    If you can let the clutch up with the engine revving and the car stays where it is then the clutch is goosed.

    Is it a new car to her? She may simply be slipping the clutch as she changes gear.

      Hi thanks for getting back to me ,no its 3 years old,I have driven it and it does increase revs for a sec then back downs,ve tried the handbrake on in 3rd gear and it stalls

      you can feel the clutch fighting agains the handbrake ,is there any thing else it could be

      is it a straightforward flywheel and clutch assy

        They are fly by wire so no cable to stick - it's possible the throttle body is a bit sticky, they breathe the crank fumes through the throttle body so they can get grubby. It might be worth spraying some carb cleaner into the body to make sure it's moving freely.

        The clutch / flywheel are conventional, nothing to worry about there. Bear in mind the ecu will monitor engine rpm and will increase the rpm if it senses they are dropping too low - if someone drove so that they came off throttle a bit too early then the ecu might be opening the throttle to compensate so when you declutch the engine rpm will rise briefly. Hard to say without actually seeing it happen.

          when you change gear the revs go up for a sec then down again like a electrical fault, its a fast up and down

            Does it do it if you are stationary, not in gear, and blip the throttle - IE on the overrun?

            Then try the same with the car freewheeling (obviously on a quiet bit of road)
