The daylight problem

[myelkovan]

The headlight of my 2014 E350 was water demaged. I bought the headlight module and installed but the daylight is turning off as soon as I start the engine.
If I swipe modules the headlight works fine.
I bought another module but it is same problem again. And I bought another used original one and this time turn signal was on instead of the daylight and the daylight was flashing instead of turn signal.

Thanks

I had a similar problem with Xentry Update Modules. I could no longer make updates to Xentry 2022.

Cause:
MB has changed the update server.

For this reason I switched to Xentry 2023. Everything works there.

Today I noticed that the left headlight module and the right one has different hardware and software number.
The left one works perfect. (4406-4408)
I bought the right one recently. (2501 - 5403) But on the module it was written 4406-4408
Now I am confused. I think I need the real 4406-4408.
First of all this numbers are actual values right? Anybody knows this? Maybe it is stored valued.

Is it possible to update the software of these modules?
I am getting the following error. The xentry we downloaded here is cabaple of doing software updates?

It`s possible with XENTRY if you have original version with online account.

based on your vin number, the headlight ecus should be the same for the left and right side. first of all i see in the photos that one is b11 and the other one is b15, so you might have a problem with them communicating with each other based that the b15 is newer than b11, also the code for the right headlamp ecu is not right for this car, based on the vin you can order A2129005424 or A2189007306. have you tried to move the coding from the left one to the right one? also were the qr codes injected in the headlamp? maybe you can trick the right one, once i had a similar problem with a w156, i took the right headlamp ecu, mounted on left, programmed and coded and moved back to right, everythintg still works normal

I dont know what to do because the left module works for the right headlight perfect. It's number is as you said A2129005424. The hardware number is 4406 and software number is 4008. And I bough the same module from eBay A2129005424 and hardware number is 4406 and software number is 4008 But after installing it, Xentry shows me different numbers as you see. I bought three different modules. Everytime removing the bumper and installing is very tring job.
I will try to buy a used one again because I dont trust the aftermarket modules anymore. I am buying correct module but it is actually differnt
actually I tried used one before and the daylight and turn signal switched. (
I will try to read left and right square codes and will try both of them but as you see module is different
