Hi guys - I’m new to this forum and just picked up a 2018 S3 Sportback and driven it home (approx 30 miles). When I turned the ignition off when I got home, I got a buzzing/humming noise from behind the dash - it’s not loud or high pitched but carries on for about two minutes. Been doing it today also on short journeys. Is this normal? Many thanks.
