A week ago I was driving the car (Skoda Fabia MK2 2008 1.4 Petrol BXW) and then stopped for a couple of minutes. When I turned the engine back on, the PAS light came on and there was no PAS. I drove it few minutes and then I stopped and re-started the engine; the PAS worked fine.
In the following days, the PAS worked now and then (once every 20 tries), but always worked on a cold start. All of a sudden, yesterday it stopped working even on a cold start and no matter how many times I try, it seems to be dead now.
I've hooked up my VAG and this is the result:

Address 01: DTCs cleared
I have tried clearing the DTCs with no success.
I have tried aligning the steering wheel (by locking it to the left and then to the right) and it only worked once although I think it was just a coincidence.
The battery is new (changed it myself in Jan 2021).
I have measured the batery and it's 13.98v when the engine is on.
I have checked the power steering fluid and topped it up.
I believe there is an issue with the wiring -- might have been cut or corroded. Another thing to mention is that I do have an issue with the sunroof and on heavy rains one of the rear tubes leaks inside the car -- the airbag cartridges on the rooftop were quite rusty when I took the top lining off.
Another thing I am going to try is to take out the connectors from the PAS pump and clean them.
Any ideas?
