OK so you do have tiptronic.
As you have already found the gearbox has two speed sensors. The earlier posters from years ago are surely saying that the other speed sensor you are looking for is not found on this car.

Find the diagram in eper that shows the part you are looking for then look for it on your car.
If you enter your vin into eper it will not eliminate all the parts that weren't fitted to your individual car but will rather show range of all parts that may have been used on production line when your car and similar models were built. In the eper lists there are loads of additional notes specifying different engines , gearboxes, markets, options etc etc
Sandaru, I read the guide by T14086 who was the first to mention the VSS wiring modification in the VSS EPS thread
https://www.fiatforum.com/punto-mk2-2b-guides/70703-punto-steering-column.html
"If your steering light has/is on it might not be steering column related,a faulty vehicle speed sensor (or sensor wiring) fault will bring on the light it may also bring on the engine warning light & even stop the speed from working.A error code (P0500) will be logged in either the steering ecu/fuel ecu or body computer.
If this is the case a wiring modification (carried out by dealer) from the speed sensor to the fusebox can be carried out...problem sorted."
It is also clear the VSS fault which can be solved by changing the wiring, originates when the car is first switched on while the EPS ECU is booting up. So from my reading of that problem, restarting the car can remove the fault and it never comes back while the car is running but it could come back again next start/turn of the key.
If I was you I would reinstall all of the original parts and see if you can get back your original fault code. Then only change the motor. Have you tried that yet?

Run a wire from the VSS signal output wire to pin 17 of the BCM connector C as shown in the picture, the other two wires on the VSS are +12v and ground from memory.
If the pin 17 in the blue plug is blank you will need to take the cover from the plug and insert your VSS signal wire.
Refer to my old post for wire colours if needed.

Here is some information I found from another member of this forum, I am not sure if the EPS steering has any input from the VSS ?
