What changes
Unit 46 (comfort module): adaptation channel 61, bit 13 = 0.
Details
Audi A4 B8 (8K). Needs the factory sunroof. The channel comes from public descriptions of the B8 adaptations and has not been confirmed by a write on a car. Odyx reads the channel's current value first and shows the change: on other versions of the unit the same channel number can mean something else — check that the current value is the one you expect. You need an ELM327 adapter that supports TP2.0. To undo, use the write history.
