A Volkswagen Polo radio asks for its security code after the head unit loses its permanent live feed — a flat battery, a battery change, a jump start or the radio being unplugged. The code is held against the serial number of that head unit, not against the registration or VIN. Fitted units: Blaupunkt Gamma, RCD 210, RCD 310, Composition. Check the handbook wallet for the code card. Once you have the serial, enter it in the radio code finder on this page.
Radio codes belong to the head unit serial number, not the vehicle registration or VIN.
A flat battery, battery replacement or radio removal is what triggers the code prompt.

Bob's never displays a guessed or generated code — if a working code can't be retrieved you get a full refund.

How to find the serial number:
Check the handbook wallet for the code card.
Try holding presets 1 and 6 with the ignition on.
If nothing shows, extract the unit with a pair of VW radio keys.
Note the VWZ serial from the label exactly as printed.
How to key the code in:
Hold preset 1 to begin entry.
Presets 1 to 4 set each digit.
Hold preset 5 to confirm.
Worth knowing:
9N (2001–2009): Gamma and RCD 200/210 units. Serial from the casing label.
6R (2009–2017): RCD 210 or RCD 310. Some builds display the serial with presets 1 and 6 held.
6C (2014–2017): Composition Colour and Composition Media — later units are vehicle-coded instead.
Polo units release with the standard U-shaped VW extraction keys.
Will a Polo radio code work in another Polo? No. The code is tied to the individual unit serial, so a radio moved between cars keeps its own code.
How many attempts do I get? Three is typical before a timed lockout, and each further round of failures lengthens the wait.
Does the Polo code appear in the handbook? Often, yes — VW supplied a printed code card that usually lives in the service book wallet.
