I can help you here, having just done mine! I made a 'how to' guide for the old Panda, and some of that still applies. But some differences - don't try to pull the control knobs off - they won't. And the plastic trim is very much more firmly clipped in place.
So, see
the guide but read on down here first:
Carefully (I used my finder nails) pry the bottom edge of the black trim around the controls away from the coloured dash. You won't get far, but enough to get a large, flat screwdriver into the gap to lever rather more. Wrap the screwdriver in a duster to prevent damage to the dash trim Or use something like
these) , and with a good old push to lever the black part away, it will eventually spring out, bringing the control knobs with it.
Now follow my guide, as the bulb removal and replacement is the same.
Once done (and check the new bulb works before doing this) push the trim piece back on - it will go with a reassuring 'clunk' as the various clips all go back into place.
