I bought a new fuel filter with fuel pressure regulator at 6.6 BAR.
After diagnostics at Digitun, it came out that the Pola had a fuel shortage problem, so this had to be addressed. As well as changing the fuel pump, a new original 6.6 BAR fuel filter went in the tank.

Part number: 1K0201051K

And here I add some more information about the individual versions:

1K0201051C= 6,4 bar (discontinued 01.11.2010) -
