I checked with my dealer using my VIN, the parts manager says there is nothing available for the i5 in terms of under-door projector or slides, those things that project down logos or messages like in the ICE 2 and 3 series. I guess they set up the "Light path" (those curve lines that go out and then run parallel to the side of the car), then called it a day. A bit of a bummer, kind of make me jealous of my wife's Audi and its "rings" projected on the ground. The light path is practical though, you don't have to open the door to have it, and it's actually more useful than a single logo under the open door - pity we can't have both!

@RainerM, I think it comes standard in i5, though I bought my i5M60 with the Premium package, but the Premium Package description in the configurator does not mention this feature. I would suggest you check whether your car has a big plastic lined slit on both sides, below the front doors, like so:

If you look into this slit towards the front of the car, when you initially unlock the car, you should see a light at the end. I think its the lens over it that does the light carpet motif, you can see the dots on the lens:

I would rather think it might be a manufacturing defect, where the lens in front of the light was never installed or fell off. Did you try calling the Genius hotline at BMWUSA? Makes no sense that a lens in front of the white light would be an option.

So here we go, no lines on the floor.
I tried today in the garage and it still is just a regular light. The settings for the Lightshow are in the Menu and seem to work. Nothing special, not sure if this is worth money. Anyway, back to the dealer and see what they have to say for themself.

buying the welcome light show will not get the “carpet” enabled.
Seems that it is a different part or something is missing.

As I said, I'm almost 100% sure now that there is a special lens that goes in front of the light, you can see the pattern in my picture, it either was not installed at the factory or fell off. Please insist on seeing the factory drawing and get your dealer to buy and re-install that lens. Please don't hesitate to escalate to BMW USA. This is so obviously a manufacturing defect.
