Last week week when I contacted customer service, they sent me a new file while mentioning FAT32. Unfortunately, this didn't work. I then purchased a new USB stick and downloaded everything again, but it still didn't work. Since I have a Mac, I wondered if that might be the problem, so I tried using my partner's Windows computer, but it still didn't work. After returning from the dealership, I called them to express my frustration, and they opened a complaint. They assured me that someone from Vauxhall would reach out to the dealer. However, the dealer claimed they couldn't resolve the issue, and I had already paid £120!
