I made a request to Porsche authorized service, they did not help in this regard. I coincidentally bought the part from an online retailer. As a result of my research, I think that the button should be introduced to the car via online.
I bought 2021 Taycan 4S without the sport chrono package, I bought the mode switch from outside. I plugged this part into its socket in the steering wheel, the button lights turn on, but when I turn the button left and right, the driving modes do not change. how can i solve this problem.
