Any idea what the difference is? Curious as to why this is needed and why it doesn’t come by default.Changing the USB port with the new E rev. ( 5Q0 035 726 E) is needed if you are iPhone user. Android Auto and mirrorlink is running and with the old USB port but if you want to use apple Car Play you have to change it. All VAG use the same ports, mine is from Octavia MK3 - second hand.
