1.4 CVT irritating gearbox problem (ratio too high)

[fwibbler]

Hi,
I have 1.4 CVT which works beautifully while it's warming up. The revs rise and fall according to throttle opening and road speed as they should do.

However, after about 10 minutes of driving (or thereabouts) the gearbox seems to move to the highest ratio it can and let's the engine labour more than usual unless you're quite heavy on the throttle and then the revs rise.

Does anyone have any idea what might be causing this?
Many thanks.
Graham

Am I the only one to encounter this problem then?
Does anyone know how I can get it fixed please?
Cheers!

I would start with checking the live data and see if the ecu commands it or if it’s just stuck. If its just stuck a flush might help.
