Occasionally when I shut off the engine after parking and exit & lock my Evoque I will hear an electronic humming sound coming from the back of the vehicle on the driver's side. If I start and stop the engine again it seems to solve the problem. I've never let it go for more than about 30 seconds so I have no idea how long it would continue to do this. It sounds like something is still functioning that shouldn't be. I'm probably not describing this very well but just curious if anyone else has experienced this.
