Have them Disconnect the amp and see if the noise still is there.
Or is the noise still there with the stereo off as the amp is on
anyway I think.
Or is it one of those 2011's that didn't get a Hi Fi system?
Do you have tweeters in the door sails?
The production date would indicate is has Hi Fi.
I will try and get a recording, the noise is electronic. Stupid question, can I start the car with the amp disconnected? Not sure if it will freak anything out. I can try that now.

The car does have tweeters in the sails, but is not the L7 system.
