Got asked on PM about this retrofit, as I don’t like sharing info on PM I quickly wrote this. Hopefully it will help.

check the wire diagrams of both seat connectors. (x14*1B and X12*1B)
Here is a clue what needs atleast to be in place.

Driver side (X14)
Add Canbus R2/KCAN2 on pin 5&6
Pin 1 power for sidebolster and lumbar (0.75mm2 fuse 10A F73)
Pin 15 Power for seat module (F127 2.5mm2)
Pin 16 Ground 2.5mm2
Pin 26 Ground 2.5mm2

If you have seat heating you can basically cut power to pin 25 and splice it to pin 15. on driver side it’s either pin 15 in case if seat memory or pin 25 for seat heating without memory. Just cut the pin and recrimped the seat connector. You need these pins:

Passenger side (X12)
Pin 1 power lumbar and sidebolster (fuse 10 F75)
Pin 8 Lin seat heating BDc A258*6B 18
Pin 15 power seat (fuse 95 30A)
Pin 26 power seat heating (fuse 128 30A)
Pin 16 ground 2.5mm2
Pin 26 ground 2.5mm2

Notes
For mirrors memory to work together with seat memory you need electrical foldable mirrors aswell.
See my signature for fuseguide to find out connectors and PIN numbers for the fusebox
I Already had seating on the manual seats so I didn’t to change climate control panel, but if you are retrofitting that aswell (which I would recommend as the wires run the same anyway) you might need climate control panel with seat heating buttons


Coding
Add 459 to VO (481 aswell if you have sport seats)
Add 494 for seatheating

FDL
ACSM:
HALL-SENSOR_2: Sitz_positions_sensor_FA(06) -> Nicht_aktiv (00)

Hi there, does the same apply if I was to go from heated seats to electric memory seats? or would there be some differences

[mrpingu]

Yes it will be similiar.
I went from heated to heated with memory so it’s very similiar.

Memory driver needs canbus pin 5and6 and power and ground on pin 15 and pin 16
Heating driver is now controlled by the memory module. Power on pin 25 is no longer needed.

Heating passenger needs linbus (pin 8) and power and ground on pin 25 and pin 26.
Electrical adjustment passenger needs power and ground on pin 15 and 16. Passenger doesn’t have memory unless you go for F15 comfort Seats which I retrofitted recently (see signature)
