Xenon to xenon+Led Retrofit (pre 2015)

Hello everyone.

 I need help with this.

 

My car is a 2015 skoda octavia III that had a standard bi-xenon with halogen bulb daytime running light 5E1941015A + 5E1941016A.

 

 

 

 

The headlights were replaced by the model that adds an LED strip for daytime running light, which also has a halogen bulb(w5w) for the position light function.

 

5E1941015B + 5E1941016B

 

 

 

 

The biggest difference between one headlight and another is that the second has a module screwed underneath to control the led strip.

N° 11 in the picture

 

 

After the change I see that the left strip does not turn on and gives an error code B121D15 in OBD11

Another problem that I find is that the halogen position lights do not turn on, they are dead.

 

The rest of the functions work fine. Low beam, high beam and Turn signals.

I thought it would be plug&play and some coding but it won't be that easy, I

 

I only coded the channels of the led drl strips and the position lights
