My car is an Audi A4 B9 from 2016. It didn't come with LED taillights from the factory, so after a lot of research I managed to do this retrofit.
To do this retrofit, you don't have to change anything on the car (just buy LED taillights and some wires must be added). Some people told me that I have to change the BCM2 for dynamic signaling, but it can be done even if you have a BCM2 that is not compatible.
If you want to do this retrofit, I can help you. Including from the mounting part to parameterization with ODIS/VCP.
