But you will still have the lower part of the tail light on.
As i mentioned in post #392 the ultimate fix is to get a 2012 rear SAM already programmed or getting it programmed in a facelift car.

The description says:
These taillights fit all 08-14 models.
Dash check light for rear fog light will illuminate for 08-11 models. It can be eliminated with load resistors (Not included) .
LED tail light may trigger dash check light. LED load resistors not included.

So does that mean, I dont have to get the SAM reprogrammed if I install load resistors?

That would be me. They look and act like OEM so SAM reprogram is required and just like OEM my 2010 cannot be programmed. Fog light lit and brake light half lit.

The 2012 facelift taillights I ordered from Germany finally arrived from a seller I found on eBay after 3 weeks. Thanks to member DOME for being the first to retrofit these lights, I felt comfortable knowing these would work. As you can see from the pics, the surface of the lights are smooth compared to the originals which are recessed in areas.

Also, the turn signal on these lights are orange, compared to the red signals on North American W204s. Who knows if the 2012 W204s will have orange or red for the U.S., but I have zero preference either way. But the orange provides a better contrast when signalling so I'll take it.

The new taillights are noticeably brighter than the old ones. The illumination on the back of my garage door was obvious when comparing side by side, even though as of now the rear fogs are illuminated as well. Even with the fogs programmed to be off, these are brighter taillights.

Comparison shot:


Here are the part numbers if anyone is interested:


Installation was fairly simple. You need to remove the plastic cover just above the rear bumper when you open the trunk so that you can in turn move the trunk liner a bit. There are two push pins and a tie hold down on both sides that need to be removed from the trunk liner so you can peel it back just enough to get your hand behind it to remove one of the nuts holding the taillights in place. The other 3 nuts you can access easily enough by removing the covers.


As you can somewhat tell from this picture, without being programmed, the rear fog lights are illuminated. There is a single LED near the top corner, and 4 LEDs above the top light strip. I am not 100% positive if the 4 LEDs above the light strip are indeed the fogs or simply part of the normal illumination. But these LEDs are found on both LEFT and RIGHT taillights. Other than that, the lights work flawlessly and the wiring harness plugs right in, with no error codes displayed on the dash.

There is a shop local to me that does have the developer software to program these lights which I will eventually take to him, the only problem is the language is in German and the translations aren't always direct so it may take some time to find the right menu, etc. BUT, I think they look great even as they are now and would not be upset if for some reason I could not get them programmed to turn off the rear fogs.



So there you have it! All in all I'm very happy with the new tails. It gives the car a fresh modern look, and I love the LED strips. Next on the list is the 2012 front bumper and LEDs, which I'm told might be available sometime in May, although I'm not holding my breath on that.

It's working perfectly so far. Plug and play. I just replaced my OEM with the FL one. No more fog light permanently on neither the bottom part of the tail light
Obviously you need to make sure the SAM has been already coded in a facelift car. That is why I recommend to buy a used one. Plus it cost me 235$ which is a lot less than MSRP.
For those willing to go this route here is the part number to look for :
