Hello everybody, my Clio 4 BJ 2013 has been whistling since today as soon as you switch it on. The whistle comes from the front of the amature board. Also, the cooling power is almost no longer available. My research has shown that there can be either too little coolant in the circulation, or a defective expansion valve, which apparently is somewhere in the front of the dashboard. It may be that with a nearly 3 1/2 year old vehicle the coolant already sowe it evaporated that the plant from one day to the next the service quittier? If it could be rather on the expansion valve: Does anyone know how to penetrate to this? Would it like to check it out in sight. Would be great if someone had had had similar experiences here and knew advice. Thank you!
