Front parking sensor not working - OEM part needed

[ralphyimages]

I've traced a problem which identifies 'Right front side parking sensor: no signal'.

 

However it doesn't say which right front side sensor is at fault, and there are three of them.  Furthermore, according to the Skoda dealership the two inner sensors are different from the third outer sensor.  So I thought I'd buy one of each and assuming one solved the problem  I would return the other to them, but only to be told that they don't accept unused electrical items back...

 

So two questions please:

would I be able to establish which sensor is faulty by getting it out and testing with a meter?

where online can I find the correct OEM part number for the sensor?

 

Thanks in advance for any input.

I'd swap the sensors right to left one at a time until the fault moves. That's the faulty sensor.
