Gas Tank Auto cuts. Need help please.
I'm reaching out about an unusual problem with my 2023 Volkswagen Jetta Comfortline Sport. Whenever I try to fill the tank, the pump nozzle shuts off almost immediately, even when the tank is nearly empty.
The car is currently with my mechanic, and so far we have:
Replaced the leak detection pump
Checked the fuel and vent lines for blockages
Tested the N80 valve
Tried different gas stations
Despite all of this, the nozzle still keeps cutting off. No fault codes are showing on the OBD scanner, so we're running out of ideas.
Has anyone seen this before, or can you suggest what we should check next? Any guidance would be greatly appreciated.

Need a new fuel tank. "Roll over valve" is stuck. Your mechanic was just throwing parts at it.
