Volvo v60 Windscreen wiper independent

Hello together I’m currently driving a 2011 Volvo v60 d5 AWD with the city safety package. For a few days the wiper has started to wipe once without any activation on my part, but since yesterday it has started to scrub the dry disc on full wipe power. I have not activated the rain sensor and as soon as it has started to wipe it will not stop even when you shut down the car and close it. Then you have to get back in and the moto Turn on r then he stops in some position. I jammed the battery yesterday and waited, after that everything worked normally until this morning. Did any of you ever have such a phenomenon?
