What changes
Unit 09 (body control module (BCM)): adaptation channel 19 = 0.
Details
Audi A4 B8 (8K). Only for bodies with a rear wiper (Avant, allroad). Before writing, Odyx logs in to unit 09 — this channel requires it. 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.
