Questions: Rad Fan and Weird Noise
2 Questions pertaining to a 2016 C63 S:
1) Now that it's getting warmer out (approaching room temperature), I often hear the radiator fan running for multiple minutes after stopping, even after gentle driving for a half hour ... is this normal? I don't recall ever hearing the radiator fan in our C43 run, even when it comes off the track.
2) Every now 'n then, the car emits a strange "sigh" type of noise (no, there's no aftermarket blowoff valves). I've been unable to correlate this noise with anything in particular and it has happened during normal driving and shortly after stopping the car. The following attachment is one example I captured via the dashcam <sigh> ... anyone know what this is and whether it's normal?
