Hello together, for a few days now the distance warning does not work in the front. The rear ones work against it. I don’t drive the car myself, is my wife her flicker, but also manual etc. have not helped me. Is there a special switch that she has operated unconsciously? I mean, it doesn’t make any sense that it “beeps” in the back, but suddenly no longer!? Or is it actually a technical defect? Zoe / Elektro / Bj 2023 Thank you for your tips!
