So I have swapped in heated seats, the additional loom parts, facia with the seat buttons and coded the ECUs but I am not getting the seats to work. If you press the heat buttons the 3 lights come on for a few seconds then turn off, and will not come on again unless you turn the ignition off/on and you get the same result.
I added $494 to the VO (CAS and FRM), and then defaulted ("SG-Codieren") the FRM, CAS, SPEG and IHKA in NCS-Expert.

What have I missed? sure it is a coding issue as I am getting power to the facia switches.

TIA
