BCM most likely as well needs an upgrade. Then LED headlights in A3 comes with a new 4B multifunction module and both lights have their own Dx units that are visible in the autoscan as well.

Yes, prefacelift one has similar light setup as in prefacelift Leon for example. It has led headlights with it's own control modules and same range control module as in Leon. This according to ETKA. Facelift one is completely different setup both normal and matrix led's.

Edit:

By the way, have you actually seen pre-facelifted A3's sold with LED headights? I haven't. I looked at Finnish auto trading website for A3's from 2015 onwards and they are all equipped with xenon's up till the facelifted model 2017 which has LED headlights.
ETKA shows LED's for 2015 model but I've never seen them live so I'm a little skeptical do they even exist :)

That seems to be case here as well. 2015 A3 E-tron and RS3 has led's here as well. Normal models just xenons.

Strongly suggest you find a set on fleabay.de and get the same as the ones that fell off your car. Unless you really want the matrix lights and expense to go with it

And also needs a new 4B multifunction module instead of the traditional range control module, yes?

Ok, interesting because ETKA says you can't. 8V0907357A would be for the facelifted LED headlights. For non-facelift lights you can use : 7P6907357B.

So from which year your LED headlights are from?

These are the pre-facelift LED headlights :

These are the facelift ones :

And these are the facelift matrix leds :

Looking at the shape of the headlight, looks like it won't fit to pre-facelift bumper either.

just as maniken says bcm rewire and afs module. 4b is for 2018 model. 2017 still use the 55 xenon range modul.
I have done this also, only no work is the turn signals when open/close car.

But if OP already had pre-facelift headlights he/she should not need to do anything else than install the lights.

Question was can OP install facelift headlights instead, would it be plug’play and this is where most of the confusion is circulating.
