Lap Timer
Unlock the built-in lap timer for performance tracking. Access this in:
[17 - Instruments] -> [Coding - 07] -> [Long Coding Helper] -> Byte 1 -> "Lap Timer active". Note: May require a firmware update from Audi.
Kerb Lighting (Cornering Lights)
Enhance visibility during low-speed turns by activating the cornering lights. Find this option in:
[09 - Cent. Elect.] -> [Coding - 07] -> [Long Coding Helper] -> Byte 4 -> Enable Bit 0.
Audible Lock Confirmation
Enable a reassuring chirp from the alarm siren upon locking your vehicle. Located in:
[46 - Central Conv.] -> [Coding - 07] -> [Long Coding Helper] -> Byte 1 -> Bit 2 -> "Anti-Theft-System: Horn Confirmation active".
Accessing the Hidden Green Menu
Gain access to the diagnostic green menu within the MMI system. Navigate to:
[5F - Information Electr.] -> [Adaptation - 10] -> Channel 6 -> Change value from 0 to 1 -> Test -> Save.
