You have to buy these two Dimmers:
- 7E0941333 ... with halogen headlights. (e.g, second hand)
- 6Q0941334 ... with bixenon headlights. (e.g, new)
... in order to cover all the possibilities in the new electrical installation (wires), now, with halogen headlights, or when you install the Bixenon headlights in the future.
The parts already installed MFSW/CCS/IC 3d or the new parts (OEM, right parts) that you install in the future will work perfectly (RLS, power windows, etc), ...with the right codings.

Apart:
It is not possible to install an original relay for the automatic lights due to the location of the supports/brackets/holders/boxes that could support/hold/fix it.
(It is possible, but the wires length/weight would be absurd)
This is not a problem, we can use one of the two screws that fix the brackect for the connection housings to the BCM support to hold a non-original Relay (12v 40A).
