Audi Symphony code entry

Switch the radio on until SAFE then 1000 shows. Use preset buttons 1 to 4 to enter each digit, then hold the TP and RDS buttons (or the right arrow) together until the radio unlocks.

Which cars have the Audi Symphony?

The Audi Symphony was fitted to the A3 8P, A4 B6/B7, A6 C5/C6, A8 D3, TT. The same unit may also appear in other Audi models of the same era.

What does a Audi Symphony radio serial look like?

It is 14 characters long and starts with AUZ, for example AUZ2Z3C1420538. You'll find it on the sticker on the radio casing.

Why does my Audi Symphony radio say SAFE?

SAFE means the anti-theft lock is active because the radio lost power, for example after a flat battery or battery change. If SAFE stays on the screen after wrong attempts, leave the radio powered on for about an hour and it will reset.

Will my code still work after a battery change?

Yes. The code belongs to the radio unit and never changes. Keep it with your car documents and you can reuse it any time the battery is disconnected.

Can I get the code from my VIN?

No. Audi radio codes are tied to the radio serial number, not the vehicle VIN. You'll need to read the serial from the radio label.

What if my code does not work?

Double-check the serial, especially the letter I versus the number 1. If the serial is correct and the code still fails, contact us and we will recheck it free or refund you in full.

How to find your Audi Symphony serial number

Follow these steps to locate the serial on your Audi radio.

Step 1

Remove your radio

Insert the four radio release keys into the corner holes of the fascia and apply gentle outward pressure. The unit slides forward. You do not need to disconnect any wires. On RNS-E and MMI units the serial can be read on screen, so no removal is needed.

Step 2

Find your serial number on the label

The serial is on the label on the back or top of the casing, starts with AUZ and is 14 characters long. On RNS-E navigation units the sixth character is always 7.
