Nothing, but it is early days.

General Comments:

A modern A4 is pretty much all the car you will ever need. Had this six months and has been excellent. Long term reliability remains to be seen, but if it is anything like Audi of the past I'm sure it will be OK. And besides, I'd be very surprised if a 2021 premium car suddenly became problematic.

S Line model is very nice, interior and exterior are gorgeous. Very comfortable and fast. Trip computer shows a steady 55 mpg. The car is fun to drive.

Plenty of space, but the A4 is no A6 or A8; taller passengers sitting in the rear may be surprised to find it a bit cramped. But up front for the driver this car's ergonomics are perfect.

Minor points aside, if you have the choice between a 3 series BMW or C-Class Mercedes, check out the Audi A4. Best premium smaller executive saloon in my opinion. Simply cannot fault this car.
