I posted this same info on the Model S thread. It probably applies to the X as well...
------------------------------------------------------------------
So, I have received clarification from my Service Center. My car is configured and built correctly.
Basically, as of the most recent configuration changes, the three-position dynamic LED turning lights ( within fog lights) are standard. The full LED adaptive headlamps with 14 three-position LED dynamic turning lights (within headlamps) are not standard and are still part of the Premium Upgrades Package (even though it doesn't mention them anymore).
The three-position refers to left, center, and right positions, not 3 LED positions. When turning left the left fog light LED turns on, when center both are off, and when turning right, the right fog light LED turns on.
In a nutshell:
Before Configuration Update:
PUP: Dynamic LED Fog Lamps & Dynamic LED Headlamps
Non-PUP: No Dynamic Features
After Configuration Update:
PUP: Dynamic LED Fog Lamps & Dynamic LED Headlamps
Non-PUP: Dynamic LED Fog Lamps
As I somewhat expected, what is now standard on the post July based model is the rather weak fog light based dynamic cornering LED light, that turns on as you turn into it. The fancier Adaptive 14 LED dynamic turning lights on the headlamp assembly, with the option to turn on or off, is NOT standard.
I'll leave it to the forum to debate Tesla's poor use of the same feature name to describe essentially two different features, essentially resulting in unnecessary confusion and grief for many folks.
