What changes
Module 46 (comfort module): adaptation channel 07 = 0.
Details
Audi A3 8P (2003–2013). The beep requires a factory alarm with a siren. The channel comes from public 8P adaptation descriptions and has not been verified by writing to a car. Odyx reads the current channel value first and shows the changes: on other module versions the channel number may mean something else — compare the “before” value with what you expect. You need an ELM327 adapter that supports TP2.0. Undo — from the write history.
Other options
This is one option of the “Unlock confirmation with the remote” setting: only one can be active.
