AC actuators? Try driving with AC / climate off and see what happens. At this stage testing is the only thing you can do

The noise is rarely heard, it is not easy to know when it will be heard. I have already clarified that it is not the exhaust sound, this noise is much louder and it only makes it once.
Generally when the car is warm after an hour of driving (and driving normal since I'm in the city) you hear the noise behind the dashboard, it's like someone makes a fist bump to the dashboard "TUC".
The strange thing is that the noise is only made when the car is stoped, not in motion.
I already tested it driving without the AC or climate control but it still makes the noise.
It ALMOST ALWAYS does it after braking, or when I hold down the brake pedal at a traffic light, or when I put it in P and then release the brake (it has done it twice already).
I think it has something to do with the brake as I have felt a slight tapping on the brake pedal on two occasions.
