Volkswagen Golf Radio Code – Full Guide
The Volkswagen Golf radio code is a four-digit anti-theft PIN that your head unit requires every time its power supply is interrupted. Whether your battery has gone flat overnight, you've fitted a new battery, or your car has been in for electrical work, the radio will wake up displaying SAFE or CODE — and it won't play a note until you enter the correct digits. This guide covers every Golf generation from the MK3 Concert to the MK7 Composition Media, so you can get back on the road with the sound you want.
Why Your Golf Radio Is Asking for a Code
The security PIN system has been standard fitment on Volkswagen vehicles since the early 1990s. It exists to make a stolen head unit worthless without the matching code. Several ordinary events can trigger the lock screen:
- A flat or completely discharged battery
- Replacing or disconnecting the battery during a service or MOT
- A blown fuse on the audio circuit
- Removing the radio unit itself, for example to access the VIN or during a dashboard repair
- A voltage drop caused by jump-starting or charging equipment
Golf Generations and Radio Fitments
Volkswagen fitted a wide range of head units across five Golf generations, sourced from Philips, Blaupunkt, Grundig, Bosch, Delphi, and Continental. The table below maps each generation to its typical radio, serial prefix, and code-entry method.
| Generation | Years | Radio unit(s) | Serial format |
|---|---|---|---|
| Golf III (MK3) | 1991–1997 | CR-2000 / Frankfurt / Concert | VWZ + 14 digits |
| Golf IV (MK4) | 1997–2003 | Alpha / Beta / Gamma / Beat | VWZ + 14 digits |
| Golf V (MK5) | 2003–2008 | RCD 300 / RCD 310 / RNS 510 | VWZ + 14 digits |
| Golf VI (MK6) | 2008–2012 | RCD 310 / RCD 510 / RNS 510 | VWZ + 14 digits |
| Golf VII (MK7) | 2012–2019 | Composition / Discover Media / Discover Pro | VWZ (older units) or no prefix (MIB2) |
How to Find Your Golf Radio Serial Number
The serial number is the key piece of information you'll need before looking up your code. Volkswagen provided two standard ways to retrieve it — no tools required for either method on most Golf models.
Method 1 — Radio display self-test
On Golf MK4, MK5, and MK6 units (RCD 310, RCD 510, RNS 510 and similar), hold down buttons 1 and 4 simultaneously while switching the ignition to accessory mode. The display will cycle through diagnostic information and show the serial number — typically starting with VWZ followed by 14 digits. Note it down carefully; this is what you'll enter on our lookup tool. On Golf III Concert units with five preset buttons, hold 1 and 5 instead.
Method 2 — Label on the radio unit
Every head unit has a sticker on its casing with the printed serial number. On Golf models up to MK6, the label is usually visible on the top or side of the unit and can sometimes be read by shining a torch into the dashboard slot without removing anything. If you cannot see it, a partial removal — sliding the unit forward with a set of DIN release keys — will reveal the full label. On MK7 models with MIB2 infotainment, the serial number is also accessible via Settings → System Information in the head unit menu itself.

How to Enter the Code on a Golf
The entry procedure differs slightly depending on your generation.
- Golf MK3 (Concert / Frankfurt): Use the five preset buttons to dial in each digit, then press the seek/scan button to confirm. The display shows the running total as you press.
- Golf MK4–MK6 (Alpha, Beta, RCD 310, RCD 510, RNS 510): Press preset buttons 1–4 to increment each digit position, then hold button 4 for two seconds (or press the seek button on some units) to confirm. The screen shows four dashes that change as you build the code.
- Golf MK7 — button-based units (Composition Colour): Same four-button method as MK6. Press 1–4 to set each digit, confirm with a long press.
- Golf MK7 — MIB2 touchscreen (Discover Media / Discover Pro): These systems use Volkswagen's Komponentenschutz pairing rather than a PIN. If the unit displays a lock, it must be re-paired to the car's gateway via dealer diagnostic equipment (VCDS or official VW tooling).
Troubleshooting Common Error Messages
- SAFE displayed on startup: Normal behaviour after a power loss. The unit is waiting for you to press any button, after which it will display CODE and accept input.
- CODE 1 / CODE 2 / CODE 3: The number indicates how many incorrect attempts have been made so far. You still have attempts remaining — double-check your code before continuing.
- WAIT 1h / 1 HOUR: Three wrong entries trigger a one-hour lockout on Golf MK3–MK6. Leave the ignition in accessory mode (or fully off on some units) for a full 60 minutes. Do not try to shortcut this by disconnecting the battery — that resets the timer but also counts as another failed cycle on some units.
- MK7 MIB2 lock (Komponentenschutz): If your MK7 displays a lock icon or a pairing error rather than a code prompt, this is not a PIN issue. It requires dealer-level component protection release. A main dealer or a specialist with VCDS access can clear this in minutes.
- Code accepted but no audio: Rare but possible if the unit has a separate mute setting active. Check the volume and the audio source selection before assuming the code was wrong.
Frequently Asked Questions
Where do I find the original radio code for my Golf?
Volkswagen originally provided the code on a small card in the service booklet wallet, sometimes labelled "Radio Code Card" or "Anti-Theft Code." If yours is missing, you can retrieve the code by submitting your radio's serial number through our lookup service — no visit to a dealer required.
How many digits is a Golf radio code?
All Volkswagen Golf radio codes are four digits long, ranging from 0001 to 9999. The code is unique to the head unit's serial number, not to the car's VIN, so if you swap in a second-hand radio you'll need the code for that specific unit.
Can I enter the code with the engine running?
It's best to enter the code with the ignition in accessory mode (position II) and the engine off. This avoids any interruption from a stop/start system or engine management cycle that might reset the counter mid-entry.
Do I need to remove the radio to get the serial number?
Not always. On Golf MK4 through MK6, the button self-test method (buttons 1+4) retrieves the serial directly from the display. On MK7 with MIB2, it's in the system menu. Only on Golf MK3 units is physical removal usually necessary to read the sticker.
Is the Golf radio code the same as the immobiliser PIN?
No — they are completely separate. The radio code is specific to your head unit and has no connection to the engine immobiliser system. Entering the wrong radio code repeatedly will not affect your ability to start the car.
Once you have your serial number to hand, getting your code takes under a minute. Enter it on our lookup tool and we'll return the correct four digits instantly. For all other Volkswagen models and radio types, browse the full range on our radio code brands page.
