I tried checking my S4 coolant level and found it to be very difficult. It’s not easy at all to look at the coolant reservoir and tell min or max levels.
How do you guys check it? I am curious to find out.

Did you check the manual? You need to check the float (under the cap) -- not the reservoir.

If you dont have your manual, you can get PDF here -- https://ownersmanuals2.com/make/audi

Since the manual is for the A4, take note of "Applies to: vehicles with 6-cylinder engine:"

Got it. yes I could see the float. I was looking in a wrong place - break fluid. The pictures in the manual I sort of difficult to read since the manual is for A4/S4.
I was able to locate it, its on passanger side in S4. All good and thank you for responding.
