Hi,

The problem is coding and matching tail light that come from different donors.

The coding of the left external tail light is successful, the right external tail light requires a change of the production date (incorrect HWEL). After this procedure, the external tail light work properly. After connecting the internal tail light, they are visible as an external left tail light or not at all.
BDC has been updated, can checked, can terminal as well. FA and SVT mods don't help. Is it a tail light or BDC fault?

Thanks for the help.

It's the taillights that are faulty. Try changing the taillights one by one.

installing taillights with retrofit adapter or without?

I tried, when I connect the tailgate central tail light individually, they are always visible as a single outside left rear light. The strange thing is that during the calculation TAL, the HW recognizes correctly but the place of the lamp is wrong, it is very strange because it is one CAN_3 line.

Of course there is the original 2022 vehicle no retrofit

LHD-RHD inner taillights are different

TypeCode also tried with no change. Today I will have the second 7 G11 LCI and I will check the tail light.
I wonder why the SVT tree gets such a mess. Lamp modules are addressed to individual channels...

As soon as all the tail lights respond, the tree will be OK! Аnd HWELs will fall into places

The topic can be closed, the tail lamps connected to another 7 G11 also do not work and the SVT reacts there by showing incorrect mounting locations.
