I did the whole car conversion from 2007 to 2010 facelift and all was great until earlier in the year when my front amber LED turn signals started to sporadically work. Now both won't work at all. I get the dreaded error in the dash now. I used this kit

Mercedes Benz W221 New S Class 2010 Headlights Conversion (face lift) Kit - YouTube

It was pretty seamless and worked fine. Before i go digging and tearing the car apart i figured i'd come to the board to see if anyone has experienced the same thing. My car is up for inspection next month and obviously won't pass without any front turn signals so i gotta get this one done asap.

The headlights work fine, its just the led amber turn signals that do not work now. Rear turn signals work, rear of sideview mirror turn signals work as well. Is there a fuse for this or no or am i looking at the harness (if anyone used this particular one), or am I looking at replacing the entire headlight since they are led

it's most likely not the headlight. Probably has something to do with the wiring or those adapter modules they sold you with the kit.

Btw, I’m thinking about doing the same ‘08 headlight conversion to the facelift version.

Is there a simple plug and play version for the headlamp conversion without splicing wires or having to reprogram the Signal Acquisition Module ?
