Built-in ActivationAudi e-tron GE — Subwoofer Menu Activation (MIB3)
In an e-tron's silent cabin every Hz counts — this activation gives you the hidden Subwoofer slider to finally dial it in.
What You Get
Audi e-tron GE trims with Audi Sound System (PR-9VD) ship with only Bass and Treble in the MMI Sound menu. With no combustion noise to mask anything, the subwoofer becomes the most audible character of the entire system — yet the factory leaves you with no way to balance it. This activation switches on the hidden Subwoofer slider through a guided, VIN-specific OEM workflow in RetroLab Pro — no dealer visit, no remote coding, no manual scripts.
How It Changes Behavior
From factorythe e-tron MMI exposes only Bass and Treble. The silent EV cabin makes every fluctuation in subwoofer level obvious, but there's no slider anywhere to tame or push the low end.
After activationa dedicated Subwoofer slider appears next to Bass in MMI Sound, so you can finally compensate for the e-tron's silent floor — tight at the charger, full on the open road.
