What changes
Module 09 (central electrics (BCM)): long coding, byte 14, bit 7 = 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 are required; works below 40–50 km/h with low beam on. 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.
