I have a very basic query -

On my Performante, when I activate the front lift, I feel a slight additional vibration through the steering wheel, only whilst the lift is operating.
I have to emphasise that it is a very slight increase in the normal engine vibration, felt through the steering wheel, but it is just noticeable.
Once the lift has raised, it disappears and obviously it doesn't do it when I lower the car.
I have only noticed it in the last few days - I have had the car for 2 weeks.
The lift seems to be working fine.
Has anyone noticed this?
Is it normal behaviour?

Thanks for your help.
