UPDATE: EPC Light and Engine Light Came On After Getting Gas at Costco, Dealership Says the Gas is Bad Quality and Want to Charge Me to Drain the Car.
Not sure the best way to update on my first post, but I received a photo of the supposed fuel sample the dealership took from my 2024 Jetta, and it does show visible separation. However, they did not provide an actual report on the composition of the fuel itself. They then gave me an updated price to drain and refuel my car with "top tier gasoline," which would cost me upwards of $900.
I brought up the idea of a potential glitch that was brought up in the comments, and some further research shows that there is a common glitch tied to the TSB update, but it seems they don't think it is related to the software and appear to be dismissive of my software concern. So I'm currently stuck and unsure of what to do and would appreciate any further advice. I've attached a photo of the gas they supposedly took from my car.
