What changes
Module 09 (central electrics (BCM)): long coding, byte 17, bit 3 = 1.
Details
Audi A3 8P (2003–2013). Only for facelift cars (2008–2013): on the 09 module of earlier 8P cars this bit controls something else — check the model year. Factory fog lights and coming home light enabled are required. 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.
