Funny sound charging?

[beez]

This morning I plugged my L2 charger into my Macan (US driver side) and heard a continuous heavy vibration sound coming from the area of the socket. I opened the trunk to verify. The car reported it was charging at 9.3 while this was happening. Unplugging or even just pressing the release button stopped it, replugging started it back up. I left it unplugged about 15 minutes and then it charged normally without sound.

Anyone else experience this?

I do have air suspension. And, now that you mention it, I recently enabled the feature to lift the suspension when approaching my house due to my driveway. Maybe the sound of an air compressor lifting my car now that I plugged in?

It did not sound like a fan. It was a pronounced vibration you could feel when touching the car. It went on the moment I plugged in, before there could be any heat.

That is the exact same sound I had. Did you ever figure it out?

Oh yes, it is indeed the air compressor for the suspension. It happens at other times too, but charging seems to also trigger a recharge of the air tank if it's needed
