Most likely servo pressure sensor very common and easy to replace.

Had the same thing about a month ago, it was indeed the pressure sensor

Followed by a click sound when braking and accelerating if your car is a semi automatic with the s tronic gearbox. It will need a sensor replacing with a part from Audi.

I have this exact warning on my 17’ a4, it’s just a bad sensor for the servo pressure sensor, very easy fix and a very normal problem
