To revive this - is this possible to do with Xentry, or do you need DTS or Vediamo...? I have done lots of coding but not on Mercedes, it seems pretty difficult in comparison..

I've not known of anyone to attempt this on the W212, but I did see someone do this on a W213 - they were required to do so as they had exported a USDM model to a country that required amber signals. They said it was a nightmare and very expensive, and coding the car caused random other things not to function.
Also, not sure if this was clear but the US cars have nothing in those slots at all. The hardware is different in addition to the software.
With enough funds and patience, theoretically anything is possible but best of luck to you. Not as simple as coding.

thanks, I actually have EU post facelift replacement lights lined up on ebay. My car is a 2014 so it is missing the wire from the harness to the SAM. I have some experience in terminating wires so as soon as I can locate the rear SAM I am in business. The only thing left is to delete the NA code which does the multi function brake/signal light on the back.
in another forum someone posted a wiring diagram on this subject and it identifies a specific code that needs to be removed. Also above we have the EU coding, now I am wondering if I need to get Xentry, DTS-Monaco or Vediamo setup to do that and then if anyone has the steps or can advise which coding method I need to start with.
I agree however the trouble that I saw elsewhere was just changing the region to Europe from NA, this causes issues with the ABS and maybe some of the emissions systems.
another method may be to get a 2013 pre-facelift coding and wiring diagram and get the coding for tail lights - as this works in North America and it’s known that you can plug and play the EU spec lights. It seems like in 2013 the red rear signal was independent from the brake lights and not combined?

You're not likely to find instructions here.. I have never seen this done because it is so complicated.
The pre-facelift cars in north America had separate, amber LED turn signals. It was the facelift that combined the turn signal/brake lights - both being red.

I too, am VERY interested in this topic. I am trying to perform the reverse, I own the 2014 E250, and have purchased the Euro rear lamps (to incorporate the amber turn signal), however, I have been unsuccessful, as the Euro lamps have a 5th connector (wire, is my understanding), I assume for the amber signal. PLUS, no one (MB Dealership) in the U.S. seems to know how to programme the Euro set-up if I were able to make the connections successful.
FYI: The U.S. spec does NOT have amber L.E.D. installed.
I would like to know if anyone has any connections as to how to make my Euro rear lamps work on the U.S. models???????
I find this most disturbing that MB would opt out of amber turn signals (the classy appearance, safety in my opinion), even if the U.S. government DOESN'T require them! This cost-cutting is right alongside the headlamp control whereby the dial-knob is lit (as well as the rear fog lamp button), but the options for parking lamp, headlamp, side lamps etc. ARE NOT LIT!

Would you have preferred halogen low beams as well? The setup isn't the best, but trust.. it could be worse.

W212, E250
I just recently facelifted my w212 with the E63 AMG bodykit. Everything works well except the rear turn signals. As others have mentioned, the brake lights keep flashing on turn signal rather than the amber lights. The amber lights flash once and then the brake lights take over. Currently, there are 4 cables running from the SAM R to the lighting harness. The aftermarket light has 5 cables attached to the connector inside the light assembly. One thing to note is that my original W212 lights had amber lights for turn signals and the moment I install my old lights, they work fine. I have tried 3 new sets of post facelift lights and they all have the same problem. Would appreciate any help I could get on this. Do I need to run an extra wire to the light connector and also do coding changes?

4 Cables from SAM and a Ground wire.
Swap the cables yellow-pink (on pin 14) and green (on pin 9), as well as yellow-purple (on pin 24) and blue-orange (on pin 10) on 6HD SAM connector.
Of course, some codings is needed to:
BREMSL_I_LI(1) nicht freigegeben 000X
BREMSL_I_RE(1) nicht freigegeben 000Z
SBL_LI nicht freigegeben 002X
SBL_RE nicht freigegeben 002Z
SCHLUSSL_I_LI nicht freigegeben 001V
SCHLUSSL_I_RE nicht freigegeben 001X
SIDEMARKER_I_LI nicht freigegeben 0027
SIDEMARKER_I_RE nicht freigegeben 0029
PRL_BrkLmpBackGrdEnable_b nicht freigegeben BG23

what year is your W212?

your car should already have the wire and coding then… pre 2014 the w212s separated turn and brake functions in North America and so the wiring was common in and outside NA. Are you in North America or elsewhere?
this should also mean the coding was the same. Were the aftermarket tails designed for facelifted cars or for pre 2014 cars? I fear that the manufacturer of the aftermarket tails put in a relay to split the facelift wiring inputs. So it is expecting a single input… you need to see the wiring and operation of the aftermarkets. People with pre 2014’s have been able to put in facelift tails and have been plug and play.
