Built-in ActivationAudi Q5 FY Facelift — Subwoofer Menu Activation (MIB3)
Your Q5's subwoofer is doing more than the MMI lets on — this activation finally exposes the slider to dial it in.
What You Get
Audi Q5 FY Facelift trims with Audi Sound System (PR-9VD) leave the dealer with only Bass and Treble in the MMI Sound menu. The subwoofer is doing real work under the cabin floor, but you can't see it or adjust it independently of the main bass — which makes the Q5 sound boomy on rough roads and thin on highways at the same EQ. This activation unhides the dedicated 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 Q5 MMI shows only Bass and Treble. The subwoofer is wired and playing, but no slider exists anywhere to balance it against the main system.
After activationa dedicated Subwoofer slider appears next to Bass in MMI Sound, so the Q5 can sound tight on rough roads and full on highways without re-EQing every drive.
