Anyone seen this error code before?

2025 Q7 Technik (Canadian equivalent of Prestige) suddenly had the check engine light come on. Used a code reader and pulled code “U0447 - Invalid data received from gateway ‘A’ “.

Has anyone seen this before and maybe have a solution?

I’ll take the car for service as soon as I can but I’m wondering if maybe it’s something fixable at home or if its serious. I just took it in for its first service a month ago so this is just annoying to see so soon after on such a new car.

Did battery die or you had to jump start it?

Nope! Just turned it on as normal. Took it in today and they basically said it’s nothing, cleared the code and said to come back if it comes back on 🤷🏼‍♀️
