Perhaps a case has become known, which is comparable to ours? This would certainly help to find more understanding among the defense experts (with this reference for the actually experienced procedure). Our vehicle braked quite suddenly and unexpectedly “in driving operation” fully automatically (!!) at approx. 40 kmh – to a standstill, fortunately in urban traffic ….. Conclusion Citroen-Germany: This from the headquarters by remote diagnosis (PKW in the specialist workshop) The reason for this is “hand-operated driver”. Recommendation: “The C4 is technically impeccable. You can therefore drive with the vehicle absolutely safely”. This does not convince us, because the cause of the error has not been found so far. We do not drive the car anymore because of fear of the repetition of the event. Our bad luck that the error occurred with us for the first time and there are no more witnesses? The dealer has been trying for two weeks now, the demanded hindrance The result is not foreseeable. Is there a tip in the matter? How do you get your right to error-free goods? Or is there only the right path with an expert? For hints we are grateful.
