Are we talking about this rubber buffer? Only at top of front doors. There are two places lower down where another might go, and similar point in rear door frame. So far as I can remember, neither of my previous Pandas had these either, so likely ’not needed’?
Edit:
Posted same photo twice and can’t edit from phone - two places on front door frame: one by the latch (as with the rear door, pictured) and one at the bottom.
