What changes
Module 09 (central electrics (BCM)): long coding, byte 1, bit 7 = 0, byte 2, bit 0 = 0.
Details
Audi A3 8P (2003–2013). On some 09 modules this setting is elsewhere (byte 7, bit 7) — check the “before” and “after” lines. The map is based on public 8P coding descriptions and has not been verified by writing to a car. Odyx reads the module coding first and shows the changes. 8P modules answer over TP2.0 (KWP2000) — you need an ELM327 adapter that supports TP2.0. Undo — from the write history.
