Hello. A red exclamation mark in the center of the clock has been lighting up for some time. It ignites and bursts 3 times and then only blinks all the time. This happens when I reach a pressure of 15kmh and flashes all the time. When you turn off the car, it will start (not flashing) until it reaches 15kmh each time. I have liquid, I don't have leaks, I don't have brick sensors. I do not know what it can be. Do you have any ideas?
