Noticed today few time while driving home, it has occasionally, randomly ticked few times, much like in older cars when the fans were knackered or rubbing agains something. Except that this only happened few times. I turned off air circulation altogether in the last 20 mins and did not hear it. So maybe fan going ... or just coincidence? Maybe someone knows what else is in that area? It's coming from behind the steering wheel are, below the dashboard.
