Which Audi models do you support?

We support Audi A1, A3, A4, A5, A6, A7, A8, Q3, Q5, Q7, TT and R8 fitted with Concert, Symphony or Chorus head units.

What serial format does Audi use?

Audi head units use a full serial number printed on a label on the casing. It is not shown on the screen, so the unit needs to come out of the dash to read it.

Where is the serial on an Audi head unit?

The label is on the top, side, or back of the metal casing. You will need to release the head unit from the dashboard using removal keys or a trim tool to see it.

What are Concert, Symphony and Chorus?

These are Audi's head unit series names, roughly equivalent to VW's Gamma/Beta/Concert line-up but badged differently. Chorus is the entry-level tier, Concert mid-range, Symphony the higher-spec unit with a CD changer or cassette. All three use the same full serial format and our lookup covers all of them.

Can I get the code from an Audi dealer instead?

Yes, but it's slower. Audi dealers can provide codes if you prove ownership with your V5C and photo ID, usually within several working days and for a fee. Our £4.99 service is instant and online, 24/7.

Frequently asked questions

Do you support aftermarket Audi head units? +

No. Our service covers OEM (factory-fitted) Audi head units only. Aftermarket units (Pioneer, Alpine, Sony, Kenwood, etc.) use different locking systems entirely.

If you've fitted a replacement head unit, check its manual or contact the manufacturer for unlock instructions.

How long does it take to get my code? +

Most codes arrive instantly after payment. Pay £4.99 and your code appears on screen straight away, with a copy emailed to you as backup.

If your serial isn't in our database, we'll tell you before you're charged and process a full refund automatically if needed.

What if the code doesn't work? +

We back every code with a 100% money back guarantee. If the code we send doesn't unlock your Audi head unit, get in touch and we'll refund you in full, no questions asked.

Before trying the code, double-check you've read the full serial correctly from the label.

Can I get the code from Audi instead? +

Yes. Audi dealers can issue codes once you prove ownership. In practice that means:

Visiting a dealership in person
Bringing your V5C and photo ID
Waiting several working days
Paying a dealer fee

Our £4.99 lookup is instant and available online any time.

Is it safe to remove my head unit? +

Yes. Removal keys simply release the internal spring clips holding the unit in place. No cutting, no wiring changes, and the unit slots straight back in when you're done.

If you don't have removal keys, a cheap set is easy to find online, or an Audi dealer can extract the serial for you directly.
