    When I start the car, it throws me the information "signaling when parking. the function is currently unavailable.
    After pressing the parking assist a continuous signal and after a while nothing happens.

    Someone had a similar problem? Original sensors - it is possible that one of the sensors does this if one piece is damaged? The error does not show, and does not work front and back ..

    Yes. If one of the sensors fails, the entire system will stop working. Connect the packaging support system to the appropriate diagnostic equipment to determine the cause of the failure.

    I have no other diagnostic device. But I have sensors from the second bumper, because it was replaced - I will try to replace it, maybe it will work.

    I understand that if one of the front is damaged, the back is also inactive in the entire system?

    This "diagnostic device" is probably a VCDS cable, maybe one of your colleagues will have it connected to you. You can check by hearing, a good sensor ticks every half second, or put your finger on it, you should feel a tingling sensation.

    It's interesting - tomorrow I will check according to what you write, i.e. by hearing and touching :) Will they tick even inactive if I get close to them to check? Because the system cannot be turned on since the message says that it is unavailable.

    I have never checked it myself, but it seems to me that the reverse should be on or press the button in the cabin.

    It worked - they all tick after turning on the parking mode as you wrote :)

    It's good that I did not start to unscrew the bumper. I went to the guy under the vaga and it turned out that there was a mistake. Once removed, everything works normally
