A VW Transporter radio code is tied to the head unit serial on the casing label, starting VWZ. Enter the serial on this page and the code is retrieved for £19.99, refunded in full if no working code can be supplied.
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.
Covers VW Transporter 1990 to present (T4, T5, T6).
Bob's never displays a guessed or generated code — if a working code can't be retrieved you get a full refund.
1990 to present (T4, T5, T6). Gamma, RCD 210, RCD 310, RNS 310, Composition
How to find the serial number:
Look for the code card in the service book, though on ex-fleet vans it is usually gone.
Try presets 1 and 6 held with the ignition on for an on-screen serial.
Otherwise extract the unit with U-shaped VW radio keys.
Record the VWZ serial and part number from the label.
How to key the code in:
Hold preset 1 to enter code mode.
Set the digits on presets 1 to 4.
Hold preset 5 to submit.
Worth knowing:
T4 (1990–2003): Gamma and Beta units, serial on the casing label.
T5 (2003–2015): RCD 210, RCD 310 and RNS 310 are the common units.
T6 (2015 on): Composition Colour and Media — later units are coded to the vehicle.
Camper conversions add a second complication: a failing leisure battery setup can drop the starter battery and trigger the lock repeatedly.
T5, T6 and why vans lock out
T5 and T6 Transporters with the RCD 210, RCD 310 or RNS 315 will show SAFE once the battery has been disconnected — and on a working van or a camper conversion, that happens often. Racking, leisure batteries, split-charge relays, awning lights and trackers all involve pulling the main battery lead.
Camper conversions are the worst offenders because the van may sit for weeks between trips. If your radio locks every few months, the cab battery is the thing to look at rather than the radio.
Getting the unit out
Two pairs of flat keys into the side slots until they click home, then a straight pull. Check first for aftermarket trim or a DAB aerial lead fitted during a conversion — it is common to find the aperture packed out with foam or tape that stops the keys seating.
The VWZ line on the top label is the serial. Photograph it with the flash off; van dust plus a glossy label makes a flash photo unreadable.
Cost and downtime
£19.99 here against the serial, refunded in full if no working code can be supplied. A dealer lookup plus a workshop slot costs the fee and the time the van is not working.
If the unit has locked out, leave the ignition on and put a mains charger on the battery while the timer runs, rather than idling the engine for an hour.
My camper keeps asking for the radio code That points at the starter battery dropping out — often a leisure-battery split-charge fault or a parasitic drain. Fixing the electrics stops the lock recurring.
Can I use a code from another T5? No. Every code is unique to its own head unit serial.
Is the T6 touchscreen coded? Later Composition and Discover units are tied to the vehicle rather than protected with a four-digit audio code.
How much is a VW Transporter radio code? £19.99 on this page against the head unit serial, with a full refund if no working code can be supplied.
Why does my T5 radio keep asking for the code? The permanent live is being interrupted — usually a tired cab battery, corroded terminals, or a conversion accessory wired into the wrong feed.
Does a T6.1 with Discover Media need a code? No. Discover Media uses component protection tied to the vehicle rather than a four-digit audio code.
