Yes, but where does the blinker fluid go? Are there different grades?

This is the correct fluid for the B9-9.5 (A thru RS versions

So does it go in that spot where the dipstick used to be?

Yes dipstick, same spot.

Oops, my bad punctuation. Meant to type yes, same dipstick spot.

Or did I?

Why isn't this "sticky noted" to the top of this thread?!?! This is awesome! Thanks for all this work. For someone like me (new S5 owner) this is SO helpful. Appreciate all the work you put in here.

@synergize I see that you suggest the tire pressures below. Do you recommend lowering pressures to these numbers?

Or should I use what's recommend on the inside of the door of the 2023 S5, 45 PSI all around.

41 Front
38 Rear

Good question. Inside my door the recommended pressure is 44 psi front and rear for the Continental 5P 20 inch tire. But a lot of members tried the lower pressure and the ride and handling was improved. After trying several tire pressures the 41 psi front and 38 psi rear seemed the best. I would air up to 44 psi all around if the car was at max load, otherwise the ride is just too hard on 20 inch tires.

The door sticker numbers are for max load. For normal load, you need to refer to the table:



This table is from my 2019 manual.

The car came with the Continental ContiSportContact 265/30 R20 summer tires. I dropped all four to 41 PSI then the sun was hitting the RR tire, I left it at that.
On a drive today the ride was much improved, a lot less harsh. I see that the chart @MH62 (thank you) posted corresponds with your findings. I think I'll drop the rear another 2 PSI and see how it rides. Then set the PSI monitor in the MMI.
