Unable To Complete Headlight Coding

Hello group,

I had issue with this 2020 Mercedes today attempting to set up a brand new Mercedes headlight housing and headlight actuation module. Programming and coding of the module were completed successfully, but when I went to adapt the light housing to the actuation module and the LED matrix module, I got an error code (shown in picture). I was reading the code with a handheld QR matrix code reader, and after failure, tried to read with 2 iPhone apps. They all read exactly the same number sequence. I then tried to read the other side of the vehicle to see if it would read properly, and it too failed. It left me wondering where the error is. 

Has anyone else experienced this situation? I appreciate any insight. I can file a Help Desk ticket, but thought I'd ask this group first. I'll also post the QR code itself and here's what I read from it:

HLI5Ch60000Ch51300Ch40000Ch35400Ch25400Ch16200CS4BPXL964FF67FF26 …E47464B434B4A…F3F3F…C 42413F42413D3A3D…A3535393C3E…D4646 …C4B48453D…B3C…A45423E37CS77A1679061 303Q01ZGS0009

Thank you.

Try HLI6 in the beginning. I vaguely remember this issue a coworker had a couple years ago. I believe help desk told him to try HLI6. Hope that helps.

On the LED lamps the module identifies channels, this refers to distinct lighting elements on the headlamp. Each LED has compensations for voltage correction, brightness, and luminance calibrated at the factory because LEDs are not consistently produceable. If you look at your code you can see each channel has 2 digits (hex 1 byte) for each…

Here's one I just did. I'm unsure if it's the same light. Led Code: HLI6Ch60E00Ch500C4Ch400C3Ch30000Ch20000Ch10000CS0ALCU3Ch37800Ch27800Ch16400CS2AA…Q002ZGS002 C code - C36461C46494CSC3 .

I was able to properly code this headlight by doing as others suggested and changing the HLI5 to HLI6. Thanks for the help!
