Here are the steps to unlock the audio system of an older Audi A6: 1. On the CD player, simultaneously press the FM2 button and the button below it. 2. When "SAFE" appears on the display, enter the password, then continue holding both buttons until "SAFE" appears again before releasing. 3. Press and hold the FM2 + MONO buttons for 3 seconds; the display will then show the password input prompt. 4. Refer to the radio code in the manual, enter the password, and then press and hold the FM2 + MONO buttons for 3 seconds to unlock the system. Below are the main differences between the older and newer models of the Audi A6: 1. In terms of exterior design, the most noticeable change in the new Audi A6L compared to the previous generation is that the front grille, which was previously divided by the front bumper, has been transformed into a complete trapezoidal grille. 2. Regarding configuration, the domestic new Audi A6L offers seven body color options: Ebony Black, Bright Silver, Oyster Gray, Arctic Blue, Polar White, Atlas Gray, and Night Blue.
Having driven an old Audi A6 for over a decade, I've encountered the audio system lockout issue several times, usually triggered by battery disconnection or aftermarket modifications activating the anti-theft feature. The unlocking process is straightforward: first, locate the preset unlock code for the audio system, typically found on a small card in the owner's manual. If you've misplaced the card, simply call Audi customer service or visit a dealership, provide the Vehicle Identification Number (VIN) and the audio system's serial number, and they'll furnish you with the code. To input it, hold down the audio power button for a few seconds until 'CODE' appears, then enter the code using the numeric keys. Don't panic if you enter it wrong once—you get three attempts before the system locks permanently. I recommend taking a photo of the code in advance for quick input next time you disconnect the battery, avoiding the hassle. To keep your audio system in good shape, regularly check the battery voltage, as low voltage can trigger a lockout. Investing in a battery maintainer can save you a lot of trouble. While it might seem minor, driving at night without music can be incredibly dull.
