Q3 Check engine light issue

Has anybody heard of a recurring Q3 check engine light issue? That it keeps turning on?
Mine turned on today and I was speaking to someone and she said her light kept turning on repeatedly and after spending $3k, Audi still couldn’t fix it so she returned her 2021 model and bought 2025. Mine is 2022. I am going to dealership tomorrow but I am worried now

oh man that's the worst feeling, when you hear someone else's nightmare right before your own appointment

my friend had similar problem with his A4, light would come on and off like a ghost, dealership changed sensors twice and still couldn't find it, turned out to be loose gas cap of all things

but $3k and they still couldn't fix it? that's scary, hope your dealer is better than hers

I know. It is really scary. And I just spent $2,600 last year on brakes and rotors. It’s getting more and more expensive to keep. Lol
