In my somewhat limited experience all autos with kickdown do it, you just don't normally feel it!
If you think about it, the kickdown "switch" must return to its original place once it has been pressed so it fights with your foot until you lift it off! You must just have a new spring or a unused kickdown!
Mine however is very soft :biggrin:
Try different shoes - it sounds silly but with boots I can't feel it at all but in bare feet it feels like a stone under the pedal!
Try putting your foot under the pedal as your are parked up. You can actually press the button down with your foot without using the pedal at all.
I have tried this whilst moving and it does nothing at all so it obviously only works in conjunction with the Pedal itself!
Cheers
