2014 Volkswagen Passat 2.5L – Car jerks and struggles during/after refueling, electrical dimming + no start?

Hey guys, I’m having a strange issue with my 2014 Volkswagen Passat 2.5L and wanted to see if anyone has experienced something similar.

Recently after heavy rain where I live, I went to refuel my car. While the car was ON during refueling, it started jerking and idling rough, and I noticed the lights dimming.

After the tank was full, I turned the car OFF and tried to start it again, but it wouldn’t start. I had to put it in neutral and get a push from a friend, and during the push, the car suddenly came back to normal and started working fine.

I went to a nearby service station, and they said it was a battery issue, so I replaced the battery.

A few days later, I went to refuel again:

Same issue happened (jerking + dim lights) while refueling

This time I kept the car ON, and after fueling was done, it went back to normal

Then again after a few days:

I turned the car OFF before refueling

After filling up, the car again had trouble starting

Needed a push again, and it came back to normal
