Hello, since the last scheduled service stay on 24.10., in which only the pollen filter and the brake fluid were changed, a quiet squeaking noise occurs with our vehicle (Q2 35 TFSI S-Tronic, EZ: 3/2023) when the brake is lifted/released while slow braking or braking into a standstill. Otherwise, the brake feels normal. Only the quiet squeaking was not there before. Could it be that the workshop just didn’t really ventilate here? I At that time, the noise was generated by the main brake cylinder and transferred through the brake pedal into the interior. After changing the main brake cylinder, it was then quiet. The noise now definitely comes out of the footroom and comes out of the brake pedal or arises. I’m not sure if it actually has to do with the brake fluid change and this is due to a lack of aftes can develop. Normally a funny pressure point would be present at the pedal or similar or? Thanks in advance!
