TBH, I also think it is part of the soul of the car. But I had a MOT(TÜV) appointment today and they were not happy about it. The car was left at the garage and they decide tomorrow if I get the new sticker when the MOT expert is back there. May be it is a matter of the amount of significance or in other words if a certain threshold has been reached they have noticed it at all.
I suppose it depends on whether it's a smooth and predictable action which is a characteristic or a "sticky" action that would be a fault.
