Well I'm fearful it is happening again!!! My first cold morning start and my 2016 S3 throws a check engine light and it is staying on. Memories of my 2013 S4 that had a CEL the first two months, replace engine sensor and developed a broken fuel gauge that after 4 attempts the dealer (Downtown Audi Toronto) could never fix!!! Now it begins with the S3 after 3625KM!!!!

Unbelievable....Audi is rapidly forming a close connection to Alfa in my mind!!

My previous car (BMW) was flawless from day one. Disappointing.

Is the fuel cap tight?

You should get rosstech VCDS and paste the codes here

I just got a check engine light after about 5800 miles (the yellow one dealing with emissions). My service adviser knew immediately what it was, as there have been some faulty sensors/leaks with the A3/S3 line. They replaced the part in a day and all is well, though he was worried it wouldn't be in stock since they're failing left and right.

Interesting...I know it isn't the fuel cap...

So Audi has put some cheap sensors throughout the 8v...great!!

How do you know it isn't the fuel cap? Good luck with your car.

The car has been fine for several weeks with no issue since new. One cold morning and the CEL. I am the only one who fills the car and replaces the gas cap.

you should get the cable so we at least know what the problem is. Also if you take it to your dealer be sure to post the codes here and what parts they used to fix it.

Sounds like you have some bad luck with the brand, I agree with getting a VDCS cable, it will really help you get the info you need.

If it's something major, you are really in the minority, particularly with the 2.0 block, super solid motor and most every bug has been worked out.
