458 heated seat error message / trunk light not working

Does anyone know which ECU needs to be configured and how to tell a 458 that it does not have a seat heating (or has a racing seat without heating) ?
Reason for asking is a error message popping up after igniton on saying that the seat heating does not work. Sometimes driver side, sometimes passenger side. The idea is to disable the heating function since it is not needed anyway. With the Texa diagnostic interface and software i was trying to find a option in one of the ECUs of the car but was not successfull. What i did also not find was a option to read out the NAG/NAP ECUs from the seats. I assume just disconnecting the ECUs below the seat would be a bad idea and just trigger more errors.

Second error is a not working trunk light. Error was set, read out and cleared (and came back imediately). Bulb was replaced but still not working, old bulb is also ok. Any idea ?
