W176 - A180 CDI Coding Led Control Module ERROR
Hello, recently i got an error on dashboard saying : Left Daylight/ Left Inidicator & Left Parking Lamp not working. I've went to a local shop and taken out the bumper and checked the led control module unit on the left headlamp.
The unit was water damaged and was cleary not working, we swapped the right unit to the left side and things were working fine.(problem was transfered to the other headlight which was equipped with the faulty module).
He told me that he will order a new led control module unit and install it once it comes (NTY EPX-ME-003 part id)... 2 weeks later i get a call and I take the car to the shop.. It turns out that it needs coding. If i used the left flash indicator it was working but it was clicking really fast in the dashboard (6 times instead of 3).Daylight running light wasnt working though.
I go to another shop who used "Launch Scanner" and we tried to programm the new control module unit with the 11 digit code inside the headlamp.
Special Function to "E1n7 (Actuation module, Led exterior lighting, left front)".
After putting that 11 digit code to LAM-S-3K string we were getting an error that it wasn't being accepted. (I was so sad for real, so much time waiting just to get rejected like that by this module)
We also tried to use Xentry but xentry wasnt able to communicate with the new LED module , it was able to communicate with the one on the other side.
The error we were getting was:
Communication Error (3.53327.1025): ComCoordinator 01025: PDUAPI: 0x0103 PDU_ERR_EVT_RX_TIMEOUT (CLL/CoP Error: Receiver time (e.g P2Max) expired with no expected responses received from the vehicle. 0x133 ERR_APPLICATION_TIMEOUT Descr: Indicates that an expected response was not received within the defined
I managed to order another led control module unit with part number A218 900 93 03 - 711307329500 Magneti Marelli (Brand) . I was told it is the OEM one.
We did put this LED module today on the car.
Whats different? Currently the flash indicator clicks 3 times BUT daylight running lights and flash do not work. With the previous module the flash was working but i was seeing errors in the dashboard.
I get no errors in the dashboard and the led lights are not working.
My concern is if the 11 digit code i have is going to be accepted by that new control module unit..
Thank you very much for taking the time to read it, any help would be appreciated.
I currently dont know what to do and i have paid 3 different people with no result at all.

It's exactly the same problem I have and in this link they are using the 11 digit code which can be found inside the actual headlight.
Someone this didnt work for me with the 1st LED module unit , that's why I'm asking if i have any chances with the 2nd one which is OEM
Xentry wasnt even able to communicate with the first led module i have bought which was NTY EPX-ME-003...It's not a known brand.
Now I got a Magneti Marelli. I just want someone who might have done this and tell me if they came through the same problems.
Thank you in advance for ur info @Plutoe
