1 Fault Found:

Double check the link where you grabbed that info from, it has been updated.

P.S.: Yes, I think it's most likely your N75.

i would swap the N75 and N18 valves see how it goes. not sure about the passat but they are on the back firewall of the engine bay, with the small vac hoses going in and out and an elec connector at the bottom. N75= black top, N18 (EGR control valve) is the white topped one.
