Unfortunately not, I think I'm out of luck! Too bad, I really loved the anti-dazzle setup of my old car.

From what I can see, both outboard LED's have the circuitry / chips that's been discussed in all the photos in this thread. I also have 5AP (Decoding For No-dazzle High-beam) and 8S4 (Decoding Variable Light Distribution).

I do not have a dedicated high beam assist button like my old 2015 with LED's, just a regular turn signal stalk.

Am I shit out of luck?
Yes you are. It means you do not have the circuitry in the steering column required to activate the GFHB. You can still code the low beam VLD though, which is still cool.

I did a fair bit of research on that when I had my 2015 M4, which had the full adaptive LED and the KAFAS camera for the speed limit info. Without the right HBA steering column, I just did not have the proper HBA computer module to be able to program GFHB, which was a huge disapointment to me. It would have been cost prohibitive at the time to replace the steering column (you cannot only replace the stalk).

I realize this is a bit of an older thread, but as MY18 cars continue to fall into the hand of second owners (such as myself), I'd imagine this topic will begin to re-emerge as new owners try to get the most out of their cars.

After reading dozens of pages of posts among multiple threads, this one nails it with the discovery of physical hardware differences between US spec'd cars and RoW, regardless of part number.

To serve as an extra data point, my MY18 (manufactured 3/2018) is in fact missing the third GFHB LED on the driver's side headlight, and as such, can not correctly have anti-dazzle coded in. Like others, my window sticker does show "S5AP - Decoding Anti-Glare High-Beam Assistant", even though the hardware itself isn't capable. If you're in question if the feature is possible, take a look at the lower-right LED array your driver's headlight and compare the number of LEDs, or simply the circuit board and look for extra resisters/SMTs.

Cheers
