On a couple of occasions now, whilst slowing down in 5th gear, I've tried to move down from 5th to 4th, only to find the gearbox restricting my change. It almost feels as though there is a hold in 5th and no matter how many times I press the clutch and try to re-engage the gear, it just locks in "no mans land", or I have to go back into 5th. Its almost held in elastic mode. The car is a diesel 2015 FEEL model.
I can feel the car pulling away whilst changing gear which is somehow restricting the deselection, if that makes sense.
