MY17 Superb Screen Washers

I have a MY17 Superb Sportline 190 4x4.

The screen washers stopped working last week - Front Screen, Rear Screen and Headlamp Washers all do not work.

Fuse is OK

VCDS Reports: 

 787212 - Windshield Washer Pump 
          B1261 01 [009] - Electrical Failure

                    Fault Priority: 3
                    Fault Frequency: 9

Question: Is there just 1 washer pump that does all 3 of these actions? Am guessing if not them I may not have a faulty pump.

Question: Anyone know the washer pump part number? (There seem to be many out there)

Question: Can you access the washer pump by removing passenger wheel and the inner wing lining to change it?

Thanks in advance for any advice - Skoda want £130 per hour to diagnose this and the car for 3 days which seems a bit crazy.
