No cover on my 2021 Iconic. I'm glad the OBD port is against the left side where it's easy to access while kneeling on the ground. Some manufacturers force you to lay on the floor on your back to find the port near the center.
I seem to always need help finding the ODB port on any new car, sometimes they blend in so well.
BTW, not that its relevant for an electric car, in many US counties the ODB port is used for annual emission performance verification in addition to its diagnostic use.
Can't believe they've made it so difficult to get to. In the UK F56 (including the SE), you don't even have to exit the car. Its just behind a small cover that flips out, just about the hood release.
