Why do I keep getting a 'Check Engine' light on my Audi A6?

I have a 2017 Audi A6 with low mileage and it keeps showing the 'Check Engine' light. I've taken it to the mechanic multiple times and they can't seem to find the root cause. Is this a common issue with Audi A6 and is there anything I can do to prevent this from happening in the future? Thank you.

Hi Renee, I understand your frustration with the constant 'Check Engine' light on your Audi A6. This is not a common issue with Audi A6, and it could be caused by a number of different factors. I suggest taking your car to a certified Audi mechanic who has experience with diagnosing and fixing this issue.
