Has anyone else found a "whirring" noise noise coming from the climate control unit after switiching the engine off . It sounds almost like a small fan running. It continues even after removing the key from the ignition, and after locking/reopening the car. Sitting in the car yesterday, engine off after a run, it ran for over 30 minutes and still didnt stop.

Has anyone else suffered from this?

Is it likelty to be a fault as it is quite intrusive when sitting with the ignition off.
