VW RCD 310 Radio Code
If your Volkswagen RCD 310 is showing SAFE or asking for a security code after a flat battery, battery replacement, radio removal, or electrical repair, you can request the original radio code using the serial number printed on the unit.
The RCD 310 was fitted in many Volkswagen models, including Golf, Polo, Passat, Touran, Tiguan, Caddy and Jetta. In most cases, the important detail is the full VWZ serial number from the radio label.

Most Volkswagen RCD 310 serial numbers start with VWZ.
How to find the VW RCD 310 serial number
To retrieve the correct VW RCD 310 radio code, you need the serial number from the radio itself. This is normally printed on a sticker located on the top, side, or back of the RCD 310 unit. The serial usually begins with VWZ, followed by letters and numbers.

Remove the radio carefully
The serial is usually not visible from the front. In many cases, the unit must be gently removed to read the label.
Check the full VWZ code
Do not enter only part of the number. One wrong letter or missing digit can lead to an incorrect result.
Use a clear photo
If the label is hard to read, take a clear photo before placing your request so the serial can be checked properly.
What is the VW RCD 310 radio code?
The VW RCD 310 radio code is a security code linked to the original Volkswagen radio unit. It is part of the anti-theft protection system. When the radio loses power, it may ask for this code before it can work again.
This usually happens after replacing the battery, disconnecting the radio, repairing the car’s electrical system, or fitting the radio into another vehicle. The display may show SAFE, CODE, or a code entry screen.
The RCD 310 is a very common Volkswagen radio, especially in Golf, Polo, Passat, Touran, Tiguan and Caddy models. Some drivers also compare it with other VW units such as the RCD 300 or RNS 510, but each radio model still needs the correct serial number before the code can be recovered.
VW RCD 310 serial number examples

RCD 310 showing SAFE? Do not enter random codes
If your Volkswagen RCD 310 is showing SAFE, it normally means the radio is locked and waiting for the correct security code. Avoid guessing random numbers because several wrong attempts can increase the waiting time before the radio allows another try.
Once you have the correct code, enter it slowly and check each digit before confirming. This is especially important if the radio has already been locked before or if someone tried several codes in the past.
How to enter the VW RCD 310 radio code
After receiving the code, switch on the radio and wait for the code entry screen to appear. On many RCD 310 units, the preset buttons are used to select the digits, then the code is confirmed using the correct radio button.
The exact confirmation button can vary slightly depending on the version of the radio, so do not rush the process. If the radio says SAFE 2 or appears locked, leave it powered on for a while until the code entry option comes back.
Drivers with other Volkswagen factory units may need a slightly different process. For example, some older radios are covered in our VW RCD 300 radio code guide , while navigation units such as the RNS series have their own code recovery details explained on the VW RNS 510 radio code page .
