2017 A3 Gas Mileage Accuracy...
How accurate are the gas mileage values offered on the display?
I am getting 36 MPG on the highway and am wondering if it's even remotely correct.
Please advise!

What's the terrain like? How fast are you traveling? What's the fuel economy when you divide miles traveled by fuel used?

Mostly flat - slight hills. I haven't had the time to measure gas and divide by miles. Just wondering if the calculation made in real-time by the A3 was basically accurate, or not.

It's typically optimistic.
You need to verify that against a manual calculation over multiple fill-ups. You can then use VCDS to adjust the built-in correction factor to fine tune the read out.

I find it's pretty accurate on my S3. I track my mileage using an app on my phone and it's generally very close to the numbers on the display in the car.
