Audi A5 Convertible Seat Memory Retrofit

Hello everyone,

I can't get the retrofitted seat memory function to work in my convertible.

The starting point was electric seats with Easy Entry and a mirror memory function. This meant that the control units and corresponding motors were already installed from the factory.

I installed the switch (part number 8W0959769) along with the corresponding cover and ran the 5 wires.

Memorytaster -> TSG connector.
1 -> 17(T32a)
2 -> 15(T32a)
3 -> 19(T32a)

Memory button -> Lock button
4 -> Mass 1 (brown)
5 -> Lighting 3 (brown/blue)

The lighting works from the switch, and I can display the activation of the SET/1/2 buttons on the measurement blocks.

Neither the red LED is lit, nor does it make a sound, and the "Set" button has no function.

I have performed coding on the door control module and the seat control module, and I have also activated the adaptation channels in the 5F module.

Have I forgotten something, or overlooked something?
