Problem with electric steering wheel on Fiat Punto can be following:
- relays,
- control unit from steering wheel
- steering wheel sensor (ring under steering wheel).

In most cases the errors showing right problems, but sometimes not.
I. E. Fault with steering wheel control module never showed directly.
So if you have spare parts you can test it. At least motor and control module are easy to change.

p. s. I did had once problem and after changing all those 3 things/ parts the problem was still there.
New parts can be also bad, but not all 3 new parts at the same time.
At the end turn up that voltage with engine running was about 14,7V…
I spent about 5-6 hours just to find problem…
