So, my Roadster (2.5, non-Sport) has a mystery noise that has shown up. I only hear it when the key is in the on position. It sounds like a cross between gurgling and a pump turning unbalanced, and seems to be coming from the area between the cooling fans and the front windshield. I have truly lousy hearing, being deaf on one side, so I can't find a more specific location. Not sure if it's louder when I open the hood and listen there as opposed to sitting in the cabin. It can't be the coolant pump, since that's running as soon as the Roadster wakes up. No alerts. Anyone have any ideas? (I'm going to have my rear diffuser replaced on the 14th, and Tesla SC said it can wait til then). Thanks for any ideas!
