Hello in the round. Our Megane was in the workshop to get a new timing belt. At the same time the water pump was changed. After I picked up the car, I heard a grinding noise one day later. So again in the workshop and let it check. Then came out that the climate compressor is apparently defective and causes these noises. What makes me stubborn is that it should be broken all of a sudden after the car was in the workshop. I don’t want to place anything but I think it’s strange. For once the boss also told me that she never had to change it! a climate compressor. Can it be that a mechanic has made a bockmist? I myself unfortunately have a keen idea of the matter 🙁
