The green symbol still appears in the display when I press the button. But no matter how long I drive, the steering wheel is no longer warm. Until yesterday everything worked and the heating has heated the steering wheel moderately but noticeably warm. Does anyone have any idea what this might be about? The fact that you can turn it on anyway and the symbol appears to make me stubborn. When the heating wires in the steering wheel wreath defe kt and no current would flow, wouldn’t a mistake or the green symbol just not be displayed? An AT steering wheel is thrown afterwards. However, I wanted to make sure before the exchange that it is on the wreath including heating wires. What could I check in advance of electrics?
